Description

Tough as nails and packing enough features to withstand four seasons of expedition mountaineering.

Alpine professionals asked for a pant that would deliver protection from the elements in four seasons of wet, nasty weather, and Arc'teryx answered their call with the Men's Theta SV Bib. Built with reinforced paneling in the knees and butt, waterproof breathable Gore-Tex Pro fabric, and a high-rise bib to fully seal out the elements, this pant pulls no punches in high alpine weather. Look towards this bib if you need a tough, full-coverage pant for expedition mountaineering, serious backcountry skiing, or alpine climbing.

  • N80p-X face fabric has a high durability-to-weight ratio designed to fend off highly abrasive surfaces like rock walls
  • Gore-Tex Pro waterproof breathable fabric is highly durable and guaranteed to keep you dry in wet conditions
  • Gore-Tex waterproof breathable fabric uses a three-layer construction that blocks wetness on the outside but still allows moisture and sweaty vapors to escape from underneath
  • Anatomical patterning gives this bib a fit that's designed to allow unrestricted movement
  • Suspenders are easy to adjust to length, and a laminated internal belt helps to keep the waist of the bib from riding up or sliding down
  • Suspenders attach at the front of the bib so you can unzip this pant, drop the seat/back, and do easily what needs to be done
  • Reinforced knees and butt further increase the durability of this pant at areas of high abrasion and wear
  • Full-length length side zippers are water tight and stop below the level of a climbing harness or backpack hip-belt
  • Water tight (WaterTight) crotch zipper opens all the way through the crotch to give you full access as needed
  • Pleated bib pockets sit close to the body so they won't catch on your upper layers when you're moving
  • Keprotech in-step patch protects the bottom of the leg openings from wear and tear and inside there's an additional ballistic nylon patch for a extra durability
  • Attachment points keep the laces of your boots in place inside the leg openings

Dry and Lightweight

  • Familiarity: I've put it through the wringer
  • Fit: True to size

My 2nd pair. Got too close to the campfire with my 1st pair. Never been dryer. Great to skin up the mountains due to lightweight material and full side zips.

for Antarctica in December

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

I have not used them yet---bought them on sale for my photo trip to Antarctica in December---but I like the cut and the quality as most things from Arc'teryx

Waterproof & nice cut

  • Familiarity: I've used it several times
  • Fit: True to size

I've been using all winter those Bibs, they are definitely waterproof, my friends kept on getting soaked wet and I kept dry (I live in Seattle). I took a medium and I'm 5'10 190lbs, I have pretty big leg/butt muscles and it did fit well. The pants seem though, zippers also, I wouldn't be worried about the longevity of those expensive pants.

Great Lightweight Waterproof Bib

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Gore Tex Pro Shell is good stuff when it's really, really wet out. These pants are on the lightweight spectrum of mostly fully featured bibs. If you're climbing or backcountry skiing and want full gore tex pro shell bibs, these are a great option. In my oppinion, they're just inherently too heavy for that application. Thus, I use them mostly resort skiing. For that use, I would like to see more pockets than just the two small ones at the chest. I'd like to see reinforcement at the cuff, I'd like to see heavier ruberized elastic at the base of the inner gator and I'd like to get rid of that lace hook at the inner gator. It always catches on my boot and is useless for ski boots. Very useful for climbing boots, however.

Bomb Proof!

  • Familiarity: I've used it several times
  • Fit: True to size

Title says it all! You can put these through anything just like the rest of my Arc'teryx gear! Although you will pay a premium for these they are worth it and if you have ever used Arc'teryx gear you already know. Try them out as I know you won't be disappointed.

TOUGH! - Great Alpine, Eh, Ski touring

These are the toughest pant I've ever owned. After 4 seasons of BC skiing and climbing they have many battle scars from crampons, ski edges and rocks, but are still going strong. As a preface I am part of a Gore sponsored program called Mountain Techs that occasionally tests their products.

Pros:
I am a big fan of the GoreTex proshell fabric. I've found it to be incredibly durable and overall breathes very well for a hardshell - though it is somewhat loud and crinkly (barely softer than liquor store paper paper). The stitching, and attention to detail is also up to Arcteryx standards which you expect for Arcteryx prices. The overall cut is great for climbing with plenty of fabric above the waist to keep a nice overlap with your jacket and keeping the elements out. This is particularly nice when wearing a pack that make the back of your jacket ride up. The internal boot gator works well on fabric or hardshell/ ski boots thanks to a metal hook on the front that keeps it in place. Finally, full length side zippers are a huge plus on these making it easier to regulate heat and remove/put on pants without having to remove boots. I use this last part for search and rescue missions as a backup rain-pant that is tough enough for brush/off trail conditions.

Cons:
Over the years I've found better pants for ski touring.It would be nice to have real pockets such as thigh pockets for a beacon on one leg and on the other, things like snacks, camera, or avalanche science tools (thermometer) that you want quick/regular access too. I also find the bibs a pain for shedding layers and poor cooling on a skin track. As a result they usually end up hanging down instead of being slung around my shoulders on the ski up. Finally, I find that metal gator hook (which is nice for climbing) a pain for ski transitions because it snags on the boot somewhere and I usually have to take my gloves off to undo it.

Beyond that it is a pant that simply will not die

This vs. Stinger

I have the Stinger bib. I love it except that it doesn't have full side zips, so I tried this one.
Crotch rides way too high when the suspender are up for me, as another reviewer pointed out. Stinger doesn't have that problem.
I also love the real pockets you get on the Stinger, but understand what is likely a weight trade-off with the full side zips.
Anyway, keeping the Stinger, and if I ever want to take them off w/o taking my boots/cramps off I'm sure I'll be a bit annoyed, but I really don't do that that often anyway, and the Stinger can ventilate pretty well.
3 stars for me personally due to the crotch fit issue. If you don't have this problem than I'm sure these are 4-5 star bibs.
I'd never pay this much for either, however, so thank god for sales.

I should also point out that the red isn't a vivid as in the picture.

Responded on

I have both bibs too. I'm 5 7 and I don't have any prob with the crotch, so I'm thinking you've got to be much taller cause that's the only reason you'd have the prob and I don't. Or you need to move up one size.
I have the red/cardinal and in my eyes, it's pretty red in deed. This color can be spotted miles away.
They should wise up and combine the best features of each bib. I don't want the choice between anything less than awesome, especially when having to pay these prices.

Bomber Bibs, Utmost Quality, No Frills

These bibs are very low key, but have all the features that are needed for mountaineering, snowboarding, skiing, or hiking in snow or inclement weather. The Gore Pro material is light but also reinforced where it is needed. The cut of the bibs is also excellent allowing for full range of movement whether you are making switchbacks on the skintrack or doing yoga in the snow ( who knows). The biggest plus other than the bomber lightweight waterproof and breathable fabric is that they are bibs. Not only do bibs provide extra protection for wind and a more seamless transition between the top and bottom, but also wears much better with a pack because there is less material and no need for a belt. I would wear these anywhere!

Disclosure: I received these bibs from Gore as part of a project that tests products for Gore.

Some features are overstated....

  • Gender: Male
  • Familiarity: I've used it once or twice and have initial impressions

I am 60 yrs old and been around the block several times. Just received bib after stalking this item since last Nov. Physical construction is very good, lots of hand work, workmanship shows. Sure hope it holds up now like what others have said below. They've had their bib for several seasons.
Featurewise, there's no obvious reinforcement in the seat or knee areas, unless you take a microscope to the surface. And the two pockets on the top front are pleated on the sides to allow for a whopping candy bar at best. No other pockets to be found. Be sure your jacket has enough pockets to carry a cell, etc.
I don't want to be a kill joy, but just a few improvements in design would make the unit so much more functional.

Responded on

DWLP, the relationship with our Chinese factory is unlike any other in the outdoor industry. Cutting corners and downgrading product are not part of the program. While not obvious, the reinforcement can be found with the use of N150P Gore-Tex in areas prone to abrasion/wear. The result is a clean look and tough face fabric in the areas that need it most. If you're looking for a similar 1/2 bib with more pockets you should check out the Stinger Bib:

Thank you Stephen for your commentary. I'm reassured, from your comments, that quality control is being maintained, but don't ever take that for granted. Keep both eyes open and focused on what they're doing. You can't be out to lunch doing business with them.

I have the Stinger Bib, a huge and generous cut, I bought this bib for the Cardinal/red color so my friends can see me when I do my face plants. Thanks for your reply and suggestion,

Can you take these off w/o removing...

Posted on

Can you take these off w/o removing boots/cramps? Ie is the zipper truly full length? Asking because on Arcteryx site they say 3/4 zip.

Best Answer Responded on

There seems to be enough comments below that the side leg zippers go the full length, and I can confirm that as well. The bottom gaiters that wrap around the boot, open up as well, and there's also a tie that actually tightens the gaitor around the boot.

Responded on

Thanks - they arrived and are indeed full side zip. That said they do ride up on the crotch badly (like another reviewer pointed out), and the pockets are borderline useless. I have the stinger and was thinking of switching to these. I think I'll keep the stingers which fit better and have real pockets. I guess Arc'teryx made the weight trade-off between full-side zip and real pockets, which is reasonable. I wish I could have both.

Best bibs ever?

  • Gender: Male
  • Familiarity: I've put it through the wringer

These bibs are amazing. I have put over 400 days of snowboarding on a pair and they are still going strong - this is unheard of! I am usually happy to get 100 days in on a pair of snow pants before having them fall apart. Even the heels have held up, and those are usually the first thing to go for us knuckle draggers. Not only are they super durable, but being Gore-Tex they are waterproof, windproof, and very breathable. I love the long side leg vents; perfect for long approaches. My only small complaint is that when I am riding/hiking/skinning with my pack on, the metal clip length adjustor thing on the "suspender" strap rubs right on a metal plate I have in my collar bone. I don?t notice the clip on my good/normal shoulder. Overall, it?s a small price to pay for the outstanding performance of the pants. Disclosure: I received these bibs from Gore as part of a project that tests products for Gore. However, this does not influence my opinion. These are the best snow pants I have ever owned. Get them, you will not be disappointed.

Responded on

Dear Han... suggest you take any 1/4 in or thicker piece of padding, like insulation material and duck tape it to the metal fastner/buckle piece that is rubbing against your metal plate. It's sort of like those pads that they have for car seat belts to help cushion the front/ torso when the belts are buckled in.

Are they insulated?

good but the fit was a bit off

  • Gender: Male
  • Familiarity: I returned this product before using it

I am 6 foot and I hover around 200lb. These fit me in terms of waist, but they rode a bit too much in the crotch (I felt like I had a man camel toe). I tried to let them hang lower by adjusting the straps, but could not find the right fit.
Back country was great about the return and made i t simple. I will try the next size...

Responded on

Bill, can you tell me what size you originally ordered...I am 5'8" and 200 lbs...I might go with that size when I order. Thx.

Must Have

  • Gender: Male
  • Familiarity: I've put it through the wringer

These bib pants are an extremely versatile item to have in your pack. The lightweight design coupled with base-layer stacking lets you tackle anything from alpine skiing to midsummer hiking. The full length side zippers allows for easy access to your ski boots, or bunched up socks. I wouldn't wear anything other than bib pants. The suspenders keep your pants up and the bib keeps your butt dry. These pants are rugged and haven't torn in years of use. The waterproofing has been flawless over the years as well. As a disclaimer I am reviewing this product as a member of MountainTechs, a Gore-Tex program.

Perfect!

  • Gender: Male
  • Familiarity: I've used it several times

These Bibs are lightweight, tough and versatile. I've used them while skiing with only a layer of wool under, they are very flexible and have great breathability. At about 6' 2" and 200 lbs, I found the Large to be the perfect fit. These bibs will also be my first choice when trekking/going backcountry trough all four seasons when the weather is demanding. Also, the full length leg-zippers is ingenious. What more can you ask?

amazing pants!

  • Gender: Male
  • Familiarity: I've put it through the wringer

These pants are incredible. I've had them now for at least 5 or 6 years. There was a honeymoon period where I was gentle with them but I have been beating on them for a few years now and they are as reliable and solid as the day I got them. Totally bombproof ProShell engineering with extra strong material sewn into the knees, behind, and ankles. I wear these pants in all sorts of conditions, all year long. With waterproof full-length zips, they are lightweight and ventilated enough to wear on a humid rainy summer day, but heavily enough designed that, with a layer underneath, they offer warmth on the coldest days on the mountain. I appreciate the way they are cut too: they are sort of slim fitting around the legs; enough so that they look good and stay out of the way (unlike so many baggy ski pants). If you lay them on their side you can see that they are cut and sewn into a sort of aggressive stance: there is just enough extra room around the knees and ankles that they look trim but feel roomy. These pants are reliable and bombproof and I can't recommend them enough. As a disclaimer, I received them as a part of the MountainTec program in order to put them to the test and review them. I have. These pants are awesome.

Bombproof Bibs!!

  • Gender: Male
  • Familiarity: I've used it several times

These are great bibs! I am 6'-5" and 200 pounds. I purchased the XL-Tall. They are slightly loose around my torso but the length is perfect. The bibs are light-weight and very comfortable. The Gore-Tex pro shell fabric is waterproof and very breathable. Full length zippers on the legs add extra breathability when needed. If I had one suggestion, it would be to add extra pocket capacity. I test products for Gore and these are by far my favorite ski pants! Nice job Arc'teryx!!

Bomber bibs

  • Gender: Male
  • Familiarity: I've put it through the wringer

As a member of Gore MountainTechs, I have the opportunity to field test GORE-TEX gear in some of the harshest conditions...and these bibs are amazing. They're lightweight and packable, yet thick enough to stand up to tough abrasion on rock/ice. They articulate well in the knee and hip, but can sometimes bunch up in the crotch when high stepping...just the nature of the beast with bibs. Extremely waterproof, have had no issues. Would recommend layering in very cold conditions, but overall excellent bibs!

Great Bibs to Keep You Dry & Comfortable

  • Familiarity: I've put it through the wringer

Overall I have been very pleased with my Arc'teryx Theta SV Bibs, and have considered purchasing a second pair for when the day comes that my first pair needs to be retired.

Activities: I have used these bibs for many mountaineering trips, ice climbing trips, and countless days of skiing.

Fit: I love the fit of the bibs. I am 155 lbs., 5'-9" tall and have a 30" waist, and 30" inseam. I bought a size medium, and have found the fit to be great.

Function: There are many aspects of these bibs that I really like. One of those features are the full length side zips, which I often partially zip down from the top when looking for extra ventilation. The built in gaiters are also very effective at helping keep snow out.

Waterproofness/breathability: I've tried various types waterproof material, and have not found a product that does a better job keeping the water out while also being breathable than Gore-Tex. The fact that these bibs are made with Gore's most durable and rugged waterproof breathable fabric (Gore-Tex Pro), makes these bibs very capable to withstand the hard ware-and-tear I expose them to.

Durability: I have had these bibs for over 3 years, and they still perform like they did when they were new. Just remember that like any Gore-Tex waterproof fabric, it does need to be maintained properly (i.e. cleaned and treated with DWR).

Construction: Superb, which is consistent with any other Arc'teryx product I've seen or owned.

These are a great pair of bibs that whether it is a bitter cold day of ice climbing, or a warm spring day of skiing, they are my go-to shell.

As a disclaimer, I am a "Gore MountainTech" and test products for Gore.
