These rain paints work well in all conditions. The Gore-tex Pro shell has excellent breathability. The pants are durable and well constructed. The built-in gaiters keep out snow and mud. The coated zippers keep water out and allow added ventilation if needed.


  • Breathable
  • Waterproof
  • Durable


  • Not as compact and pack-able as other rain pants.

These pants are keep out driving rain and snow and are the best all around outerwear for travel in wet and cold conditions. The pants keep you warm in camp and breath on the trail — layering is easily accomplished as the pants are large enough to permit this. I have traveled through thorns (albeit nervously), however these pants came out without a mark.

Bottom line: A+ best rain pants hands down for trekking in wet mountain conditions.

Another well made product from Arc'teryx. I'm a 34 waist and bought the large. The fit is good with room for layering and still have room for movement. Zippers are great and plenty of ventilation.

This is a very good product.

These pants are great for any wet conditions. The Arc'Teryx Beta AR Pants have articulated knees for easy movement going up or down the mountain. They have performed excellently mountaineering, skiing, and in the rain. Arc'Teryx clothing seems to be the most well built compared to all other outdoor gear. The downfall is you pay for the quality.

- OMCgear refers to the men's version

When you are the Arc'teryx Men's Beta AR Pant, life is pretty dang good. You relish in the fact that you are an elite snow pant that can take whatever hellish winter conditions your owner or the world can throw at you. No biggie. You were made with a three-layer Gore-Tex Pro Shell, so you guarantee waterproof protection and breathability. The N40r-X fabric seals out any adverse weather, while being supple and notably soft to the touch. On the hard-wearing areas in the seat, bottom legs, and knees Arc'teryx placed the N80p-X fabric to offer extra protection and durability. This pant is fully seam sealed with micro-seam allowance that reduce bulk and weight and improve breathability, so your base layers will remain nice and dry. To further keep out the elements, you, the almighty ski pant that you are, have 3/4 length WaterTight side separating zipper, which doubles by being easy to remove over boots and crampons. A trim athletic fit with articulated shaping delivers mobility. Then there's the elastic waist with adjustable front closure, the Keprotec instep patch to protect against edges, crampons, and boots, and the Cordura powder cuff to keep the snow out. Yep, you've got it all.
