Arc’teryx Beta Pants Black Reg

The Arc’teryx Beta Pant Men’s is a lightweight, waterproof shell pant built for alpine travel and hiking in unstable conditions. Designed for days when weather changes quickly, it delivers reliable protection without adding unnecessary bulk. The construction combines PFAS-free GORE-TEX ePE with a recycled face fabric, creating a barrier that is waterproof, windproof, breathable, and durable enough for repeated mountain use.

For moving through wet trails, exposed ridgelines, and longer hiking days, the Beta Pant balances weather protection with comfort. The addition of GORE C-KNIT backer technology gives the inside a softer, quieter feel while maintaining breathability. This makes the pant easier to wear over extended periods, whether layered over trail pants in persistent rain or packed as emergency shell protection.

The design is focused on mobility and practical layering. Articulated shaping supports a natural range of movement on steep terrain and uneven ground. The low profile stretch waistband keeps the fit streamlined under a pack or harness-compatible layering system. When conditions shift, the 3/4-length separating side zips allow fast on and off over shoes or boots, and also provide extra ventilation during higher-output sections.

Details are purpose-built for technical use. A single thigh pocket keeps small essentials accessible. Laminated instep patches add protection in high-wear zones, helping guard against abrasion and cuts. At the hem, eyelets for shock cord attachments offer added adjustability. A built-in RECCO reflector supports search and rescue visibility in emergency situations.

Arc’teryx also updates the Beta Pant with lower-impact materials and treatments. The fabric uses an FC0 DWR finish that repels moisture and is free from intentionally added PFAS. It also contains recycled content, a dope dyed backer, and materials that meet the bluesign criteria.

Available in Short, Regular, and Tall inseam options, the Beta Pant is well suited to users who need dependable shell protection for hiking and alpine use, with a clean silhouette and technical detailing that stays focused on function.
