Arc'teryx Men's Gamma Pant

Flexible softshell pants are a versatile choice. The men’s Arc’teryx Gamma pants have been on the market for years, and they work equally well on hikes, climbing trips, and as part of an outdoorsy everyday outfit.

Designed for cool conditions, the Gamma pants have enough freedom of movement for any sport, as the fabric contains 12% elastane. The tightly knit fabric and DWR treatment offer some protection from light rain, although you’ll want to bring actual rain pants with you for a rainy hike.

The inner surface of the pants is very comfortable when worn directly against the skin, but in cooler weather, you’ll find it easy to add long johns underneath for extra warmth.

• Regular fit
• Fortius DW 2.0 softshell fabric provides wind protection
• Updated version for spring 2026: the fabric is now carbon compensated, the buckles have been updated and the cut is now 100% compatible with the Gamma product group
• Drawstring at the leg ends

• Integrated belt with low-profile metal buckle

Note! If you’re a long-time Arc’teryx fan, the sizing has changed: small sizes are smaller and large sizes are larger than before. Please refer to the size chart.

The size number indicates the waist circumference in inches, similar to many denim brands.
