Product Details

The Arc'teryx Men's Beta Pant is built for the kind of days when the forecast is only a rough suggestion. Lightweight and easy to layer, it gives you dependable weather protection for hiking and climbing without feeling overbuilt. The waterproof, windproof, breathable construction keeps rain out while letting moisture vapour escape, which matters when the trail steepens or the pace picks up.

What stands out in use is how practical it is when conditions turn. The 3/4-length side zips make it easy to pull on over shoes or boots and give you extra ventilation when you need to dump heat. Arc'teryx also uses a PFAS-free GORE-TEX ePE membrane here that is lighter and thinner than previous materials while maintaining the same strength and durability. If the face fabric starts wetting out sooner than expected, a wash and dry will help restore the DWR finish without affecting the membrane's waterproof performance.

EASY LAYERING

The ¾-length separating side zips make these easy to pull on over shoes and boots when weather moves in. They also add ventilation when you need to release heat on the move.

BUILT FOR MOVEMENT

Articulated shaping and a regular fit give you room to move and layer comfortably. Laminated instep patches add protection against cuts and abrasion in rough terrain.
