Description

Low weight doesn't mean dainty

The Arc'teryx Men's Beta LT Jacket gives you the lightweight construction you want for fast-and-light alpine assents without sacrificing any of the weather protection you need for life in the mountains. The LT takes the bombproof AR and slims it down in the weight department. A Gore-Tex Pro three-layer, fully seam taped shell holds off the worst storm you'll encounter and breathes incredibly well. The LT is made from N40p-X shell fabric, which is supple, yet durable. The fit is trim, but with e3D Ergonomic 3-Dimensional patterning, including articulated elbows and gusseted underarms, that enhances your mobility and comfort in tight spots.

WaterTight zippers will block out any and all moisture in your wake, and when it gets bad, hide under the helmet-compatible, fully adjustable storm hood with a laminated brim and lock down the cuff tabs and hem drawcord. Even with all this protection, the Beta LT Jacket still only weighs 10.1 ounces, which is less than in years past.

  • Gore-Tex Pro Shell membrane (3-layer)
  • N40p-X shell fabric
  • Fully taped seams with low-bulk microseam allowances
  • WaterTight zippers
  • Helmet-compatible DropHood with laminated visor
  • Die-cut hook-and-loop cuff tabs
  • 2 high hand pockets and 1 internal laminated pocket
  • Trim fit with e3D patterning

Here's what others have to say...

I just ordered an Beta LT jacket (size...

I just ordered an Beta LT jacket (size XL). I am 6'2", 195 lbs. I typically get warm quickly so my base layers are often minimal in nature (i.e. base layer t-shirt + light down insulation). I have a slender, athletic build (an ex-swimmer turned skier/cyclist) so I usually enjoy a more slender cut. Can anyone comment on if they think an XL will work for me??

Best Answer Responded on

It's all about your chest measurement. This jacket as a trim fit, but the L has a 43 inch chest and the XL has a 46 inch chest... which is a pretty big jump between sizes.

FWIW... I wear a 44 sport coat and find that Arc's large is a nice fit if I want something that's close to me.

Responded on

These are pretty trim fitting jackets,So sizing can be a bit tricky. If you get very warm you may look to a jacket with pit zips. I would have suggested a Large in the ALpha AR jacket. It has more room in the torso and a slightly longer cut, plus the added bonus of pit zips (with minimal weight penalty)

Responded on

So how do you find the fit? I'm looking at the XL too. I'm only 6 foot, but I have a 46inch. I usually buy XL, but most jackets end up being boxy and baggy. Does the XL trim fit well too?

Awesome Fit

  • Familiarity: I've put it through the wringer
  • Fit: Runs small

I love the narrower cut of the Beta LT jacket. I am 5'10" and 165lbs with monkey long arms. I fit a medium perfectly (for reference I wear a medium Alpha SL and a small Theta AR. front zipper is 28" long so it just comes down over you pants/shorts and has a drop of 3-4" in the rear.
The chest is 2-3" narrower in the torso than the alpha SL and shoulders are a tad narrower. The arms however are plenty long (bonus). 2 large chest pockets can fit nearly all i need for day excursion and an inside chest pocket is perfect for my phone or wallet.
The new pro shell breathes relatively well but it still needs some pit zips on muggy rainy days.
Great jacket - love the way it fits but looses 1 star for lack of pit zips

if youre layering, you need to size up. I'm 5'9 200lbs. I was misinformed and got a large. It was too tight with the layers. so I had to go with the XL. This jacket is my best all season wear, just wished it had pit zips like my alpha hybrid SL.

Responded on

Check out the Beta LT Hybrid if you'd like a similar jacket with pit zips and a different hood configuration.

Tango7,
I am 6'0" and 180, so we are about the same build. I would suggest the medium if you are looking to use the Arc'teryx Beta LT Jacket with only a base layer or light midlayer underneath.

However, if you want a more versatile jacket that you can layer over fleece or down in a variety of conditions I would recommend a large for sure. The large will still fit trim and will be a good length for you, but it will have that little bit of extra space in the chest.

Responded on

I tried both medium and large and the medium was alright with a base layer but anything else was tight in the hip area. The large just doesn't fit right. The part around the neck fits much more loose and the sleeves are longer. Jacket is designed to be trim

Large Beta LT

  • Familiarity: I've put it through the wringer
  • Fit: Runs small

I got this jacket in both medium and large and kept the large. The medium was too tight around the chest area for me. The large fits identical to a Medium alpha LT. The key differences for anyone comparing the two are:

1. Beta LT uses thinner/lighter vislon zipper
2. Beta LT has 1 less hood adjustment
3. Beta LT brim is less bulky than the Alpha LT
4. Beta LT has No pit zips
5. Beta LT logo is not stitched and its made in China

I like the Beta LT over the Alpha mainly for the pockets and the fact that I never ever used the pit zips in any of my shells.

Responded on

you said you tried both and the large felt the best but you never gave your measurements. what

I tried this shell on in size M. I honestly...

I tried this shell on in size M. I honestly like this shell the best out of all Arcreryx shells but it just doesnt fit me right. If I size up, I am afraid it will be too large with long sleeves. Anyone sized up in this from their normal arcteryx sizing?

Responded on

Tester.
where do you find it tight? shoulders or torso. I wear a medium in the Beta LT (and mediums in the FL and SL range of jackets) but usually wear a small in the Theta and Beta AR lines.
why not go with a medium Beta AR?

Responded on

The Beta AR has longer sleeves and I like the storm hood over the drop back. It was tight in the torso and I got the Alpha FL and that being a trim fit fits perfect. They have different cuts. The beta is shorter and the torso for me is just not doable

Finally - it's Slim!

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

After discussion with Arc'teryx representatives, I was told that this year (2013-2014 Winter), the Beta LT and Alpha FL are the slimmest jackets available with very similar cuts. Now why the Alpha LT wasn't included in the discussion, I have no idea. Because I wanted the slimmest available jacket in GT-Pro, I went for the Beta LT. I have no regrets. I am ~37" chest, ~30.5" waist, 125 lbs, and my previous favorite jacket was a ca. 2009 Norrona Falketind Pac-Lite jacket (size S). When I replaced it was a ca. 2012 Norrona Falketind GT-Pro jacket (size S), I was really let down because the cut of that jacket is far larger (especially in the upper and lower torso). Now, with this Beta LT (size S), the fit is fabulous - it's slim but I have full range of motion of my arms and have room to fit a Mountain Hardwear Nitrous insulated layer. The construction is top-notch (Made in China, if that matters to you). BUT, there are a few drawbacks that keep it at 4.5 stars if that was an option to select:
1) The hood doesn't cinch as tight as Norrona's. It does cinch down a fair bit, but if I'm not wearing a helmet or another hooded layer underneath, it doesn't quite go tight enough to grasp onto my head like Norrona's.
2) There are no pit-zips. I realize this is by design, but because I tend to use it for more active pursuits, I would have loved the addition.
3) The main zipper is smooth, but I must say that it feels kind of dainty in hand. Only time will tell if it puts up with the abuse over the next few years - I hope so!
I find these to be extraordinarily minor criticisms, so I'll still bestow 5 stars.

Excellent Jacket

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

Fit: 6'2" 190lbs - Large
Fit is athletic with enough room to layer all but hte thickest of down jackets. Fits perfect with a Atom LT.

The proshell on the lighter weight LT is much nicer in my opinion then that on the AR the ripstop is on the inside instead of the outer layer so its not visible, meaning a smoother face on the fabric.

Jacket is long in the back which is perfect for the hip cut.
Pockets are easy to access and large. the new style zipper on the front works great, really happy to see the laminated zipper gone.

Wish it had pit zips, but more out of nostalgia. Fabric breathes well enough I haven't needed them yet. Seems are stitched and welded perfect, arms are articulated so they are not restrictive when you move. large cuffs so you can get a large gps watch in and out without issue.

Perfect year round jacket, light enough to wear on its own in the summer and just enough room to layer for the winter.

Another Note: The pockets are gore on the interior as well so they cannot be used as vents

Responded on

Do you know if the sleeves are as long as they are on the beta AR?

Responded on

They are from what I can tell. Have not compare side by side but fit in the AR Medium is similar to the LT Large

Responded on

I have a Beta AR in (M) and the sleeves are just a tad bit long. The Alpha (LT) I tried was perfect in the sleeve department but no pockets was a deal breaker. Are you saying the Beta LT (L) has a similar fit as the Beta AR (M)? If so then I can get the (M) in this jacket and it should be perfect.

Responded on

When i tried on the Beta LT (M) the sleeves were the correct length but it was very tight in the torso. Like I said, if I was to go with the AR it was the (M) that fit correctly.

Responded on

Gothcya, thanks. I went with the Westcomb Switch LT instead. Their hood design is just awesome. I might pull the trigger and see if this one compares.
