Featured in Backpacker Magazine and Telemark Skier, the Men's Magnum BC Pant may be FlyLow Gear's most versatile winter pant. On the inside, this pant has a brushed lining to aid moisture transfer away from your skin and, on the outside, the shell material is stretchy and tough as nails. A nearly full-zip outer vent allows you to take these pants off even if you can't take your boots off. This is a pant targeted at the turn-earning, ski-touring, and knee-dragging crowds.

  • Intuitive Fabric utilizes a waterproof breathable membrane that allows sweat to escape while protecting you from external moisture
  • External DWR fabric treatment repels moisture and causes water to bead off the shell fabric
  • 1000D Cordura reinforcements increase the overall durability of the nylon shell fabric
  • Fully taped seams further improve weatherproof protection by stopping leaks at seams
  • Loose fit provides room to move and room for plenty of layering underneath
  • Articulated knee box gives your knee extra space when you're touring or hiking
  • Inner and outer thigh vents work together to cool you down quickly thanks to cross ventilation
  • Hidden tabs allow you to adjust the fit at the waist quickly and easily
  • Five pockets store gloves, goggles, keys, and lifty bribes
  • Seamless reinforcements improve the durability at the bottom of the leg cuffs
  • Internal powder gaiters include stretchy material that closes securely around the tops of your boots

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

After several trips to Jupiter Peak from McConkey's in PC, the full length vents were extremely appreciated. Tough pants, excellent features, super construction and detailing. Phone in front pocket, wallet in rear, no issues. I'm 5'9" 168- between a small and medium. Went with a medium. A little baggy, but nothing too bad.


Love these ski pants!

  • Familiarity:I've put it through the wringer

I've skied in bibs forever and thought I'd give pants a these pants. I bought the plum color. They're true to size (32 waist/28 inseam and I bought a size small). Just "baggy" enough for "new school" but an old guy like me can still sport them. the length is perfect...right at the bindings.

Love me some pockets too....the front flap pocket is perfect for stuffing spring gloves in (or a ski pass, something not too bulky, etc). Each pocket has a zipper and velcro to keep the flaps down.

The cordura knee patches and ski edge guards are burly. The waist adjustment and belt loops work fine and allow for a lot of adjustment. Taped seams, full zips, inner cuff to keep the snow out....really nice garment.

I love these ski pants.

keeps you cool and dry

This pant performs exactly how it is designed. What sets it apart from others is the fit. Plenty of room in the legs for getting after it in the mountains. These breath pretty well and keep you very dry. They thought of everything with this softshell pant, but they could have left off the cargo pocket. I don't really like having junk clanking around on my thigh while I am skiing.

Magnum BC Pant

  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:Runs large

I only have a few days with these pants, but I can share some design/fit information.

I am 5'9" 165lbs 33x30 pant. I tried on both the Medium and the Small, and went with the small. I could have gone either way depending on if I wanted a very loose vs. traditional fit. They fit slightly slimmer than my Patagonia Snowshot pants, and are shorter so I don't step on the cuffs in the parking lot.

The material doesn't have much stretch to it, but I suppose there is some. The pockets zipper down to close which takes some time getting used to. The outer leg zips are awesome, but start an inch from the top instead of 12" down so they look a little odd when unzipped. Inner's are great.

Bomber pant

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

These pants have worked out really well for me. I especially like the pocket on the left thigh - perfect size for an 8 oz flask. The material does stretch somewhat, breathes really well, and make for a very comfortable day of riding.

The side zippers and closure at the bottom of the pant make for easy adjustments to your boots or base layers when they tend to move around.

So far absolutely no issues with the pants "wetting out" or other signs of wear. I am 6 1" 190 lbs and the medium fit great - out seam is a perfect length.

Well designed but durability issues

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

I really wanted to like these pants. They appear to be made very well, fit me great, and seemed well thought out by the folks at Flylow. Unfortunately a few issues have arisen for me after one season of use.

First of all, the pant eventually seeps water in when I sit in the snow. I know they only have a 10,000 rating, but still- a $300 pair of nice ski pants just shouldn't let water in from sitting in the snow for a bit. Secondly, after one wash, the soft-shell material has become super wrinkled and prune-like, and took on all sorts of stains from just my laundry detergent. This doesn't affect performance, but again, I don't know why this should happen with a higher end ski pant. Thirdly, I had a LOT of seam tape peel, and stitching in the seat/crotch unravel. I sent them back to Flylow, and they re-glued the seam tape back down, but did nothing with the unravelled stitching. (They didn't charge me since it was a warranty issue).

Like I said, I really wanted to like these pants. Flylow seems like a cool company, and it seems like others have had a more positive experience than I have. I just don't think these pants measure up to anything from Patagonia, Arcteryx, OR, etc.

That's actually not true at all. Gore-tex or other technical fabric eventually loses it's DWR coating (due to general wear or other contaminants), and needs to be cleaned and revitalized. It's important to use a non-scented or technical fabric specific detergent, and then rinse a lot. Often a run through the dryer can replenish the DWR, but after a few washes you'll have to apply nikwax or another water resistant coating.

Never washing foul weather gear would be terrible- it would eventually stink and completely wet out once the DWR was lost. Not sure where you're getting your info from.

Im getting my information from 30 years as a mountain guide in Southeast Alaska rain forest, and as a 62 year old born & raised native of Alaska.

You are correct in theory, but after about 2 seasons on a jacket I've never been able to get them 100% revitalized, even after carefully following the procedure you speak of.

I now wear a Gore-tex jacket and carry a dry spare jacket to change into for the following day. I find this system works well. These jackets are just to costly to buy new each season even with pro-deal price.

And BTW, I absolutely love my Flylow BC pants. They've taken a beating and have held up great with no breakdowns at all.

They keep me dry and warm. I consider them the fortress of my outdoor gear.

Thank You Flylow !

I've rarely ever washed my outerwear and when I did, I made sure to not use detergent. Being said, yes they can seep after prolong exposure to snow out of the box. I've made it a habit when I get new outerwear to apply some extra Nikwax to those high wear areas like the seat, thighs and knees.

Sorry you had a bad experience, I've had the same 2 pairs of flylow pants for 3 years with over 150 days of use a year with minimal signs of wear.

And that can happen too! Actually I picked up last summer a pair at a local ski shop and found all the zippers were installed backwards(explained the %80 off) After a visit to seamstress and $45 dollars to fix them all, they're worth it.. They are still a young company and production runs will have some defects. Its part of the reason they have a great return policy (OR is the sameway).

I've had my Magnum's for about the same amount of time as you Reid and about the same amount of days. Mine finally hit a point where re-treating them with Nikwax no longer works. I've used the tech wash and the spray to no avail. Pants were great, but seemed to be a tad short lived on the waterproofness.

I love this pant. I have skied in the Chemical pant, the Stash pant and now am fully on board with the Magnum BC. For me it's the best balance of style and function that I've found in a pant and like all of Flylow's pants these things are built tough as nails. They're not overly stretchy but I find that the fabric has enough to give to be comfy for big tours but enough tenacity to hold up to resort day poundings. I love the full outer leg zips and even though I almost never use the full zip for on/off functionality I love that I can customize the amount of ventilation that I need to suit the day. The reinforced knees and cuffs will add seasons to the life of these pants as well. I'm 6'3'', 185lbs and like a little bit baggier fit and the XL fits me perfectly.

Not right for me

    Wanted so badly for these to work but they don't fit my body. I'm 6'-4, 210 and the XL cut is just not right and they were a bit short. I would agree with some of the previous reviews that the BC pant is not as stretchy as the description might indicate. I have the FlyLow "stash"pant in an XL and love them from both a fit and performance standpoint. Seems the stash has a longer drop and a longer inseam which is ideal for my tele-fun.

    Great Pants - Bit too Baggy

      I bought these specifically for backcountry touring, Flylow is a great brand and I had read the reviews prior to purchase. Trying them on, the material was not as stretchy as I had hoped, the full length side zips are awesome, and the construction was solid however i felt that these were better suited to in-bounds skiing where trudging up a hill is less likely. I skied Snowbird in these and hiked Baldy a couple of times and found that the fabric stretch on the knees was not sufficient (I'm 6ft 3, 200lbs and bought the XL). I'd have kept these if i needed a pair of resort pants but returned them in favor of some Outdoor Research soft shells. All in all, great pants, just not for hiking.

      good looks and durability to boot!

      • Familiarity:I've put it through the wringer

      I have some older Magnum pants that have been used and abused for the past three seasons, and they still look great. The heavy duty knees and cuffs hold up to abuse, and the venting is great. I always ski with the BD knee pads and usually just put them on through the vents in the parking lot while gearing up ? the vents are that big.

      The issue I have had with the pants is actually a wear and tear issue that is a result of my boots. The stitching that holds the rubber part of the gaiters on to the nylon fabric has been coming undone since I got the pants, but so far the rubber is still attached and the gaiters still keep snow out. The stitching coming undone is a result of the sharp metal buckle on my booster straps catching and pulling on the material really an issue with the booster straps and not the skis.

      When I got the pants they were my first Flylow purchase, and I new right away the company had a cool vibe. The first step of the wash instructions? "Drink cold beer." Yeah, this is my kind of company...

      Technical fabric, bomber durability, good fit, comfortable. No complaints here...

      Durable, breathable, backcountry pant

      • Familiarity:I've put it through the wringer

      I purchased these pants a few seasons ago and they are still in great shape. I've done a ton of bushwhacking through the woods of ME and NH, skied in the rain, toured, hiked bootpacked, and they have been my go-to pants. The 1000D cordura is key for long lasting bottoms/knees. They are lightweight and breathable. My only complaint which is why I gave it 4 stars is the waterproofing, but it clearly states its only a 10,000 rating, so some water will seep through on a deep day. The pockets are pretty good on my pant (could be bigger) and the new pants are upgraded with more storage. The side zips are key for spring skiing! Another great product from Flylow!
