All in all, an absolute 5-star product.


  • Durable
  • Waterproof
  • Stylish
  • Comfortable

I've been using these pants for three years now and have nothing but positive words to say. I use them in a variety of sports, activities and conditions, but primarily for mountaineering, and backcountry and resort skiing.

They are incredibly durable and, after three years of use, are still in great shape. All the high-wear areas are reinforced with stronger fabric or extra stitching and this extra quality has made a huge difference.

The different size and inseam options also make for an excellent fit. I have a short inseam and had not previously found shell pants that fit me satisfactorily. These do and it is a pleasure not to have extra fabric hanging down over my boots. 

The full length zipper allows me to regulate temperature very effectively and seals out water without any issues.

The only critique I have is that I wish the pants came with a small strap to tie the internal gaiters around the bottom of the boot. This would be a nice addition, as the internal gaiters do have rivet holes for such a strap.

All in all, an absolute 5-star product.

Bomber bibs...packable, waterproof, light, and super durable.


  • Durability
  • Waterproof
  • Articulation


  • Tight in crotch

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.  That is truly the only con I can think of with these things.  

Extremely waterproof, have had no issues.  Would recommend layering in very cold conditions, but overall excellent bibs!

Great for winter activities.


  • Waterproof
  • Durable


  • Cuffs too tight

I have used these for winter mountaineering and backcountry skiing. The fabric is thin but has been really durable when skiing through the trees. I really like the pockets on the bid for storing small items.

The only issue I have with the pants is that the cuffs are really tight around my ski boots. On the bright side, no snow gets in.

I am 5'11", a 180 lbs with a 34" waist and a large fits good.

Arc'teryx gave the answer with the Men's Theta SV Bib. What was the question, you ask' Alpine professionals asked for a pant that would deliver protection from the elements in four seasons of wet, nasty weather. Ask and ye shall receive! Look towards this bib if you need a tough, full-coverage pant for expedition mountaineering, serious backcountry skiing, or alpine climbing.The Theta SV Bib is built with waterproof breathable Gore-Tex Pro fabric laminated to the N80p-X nylon, sealing out any adverse weather while being a supple and notably soft to the touch. Reinforced paneling of N15-p-X shell fabric in the knees and butt is burly enough for any adventure, and the reinforced Keptrotec instep patch can take a nick from a crampon or two. The high-rise bib is an alpine classic; a streamlined profile with an integrated elastic waist to keep warmth in and snow and drafts out, and a full drop-seat option that does not require removing the suspenders and is compatible with harnesses make it a no-brainer. The Cordura powder cuff seals out the snow, and the full separating two-way zippers let you vent as needed or remove the bib over boots with ease. Now, the only question alpinists are asking is, "What mountain should we conquer'" You're on your own there.
