FLEXIBLE SIZE & ACCESS
We chose a roll top format so the bag can compress down to a small size but when needing room for extra gear or layers the roll top can expand. The ALPHA 31 features three access points. When compressed, the front zippered panel acts as the main access to the bag. When fully loaded, the roll top becomes the key access point and the front zipper allows for access to items lower in the bag. For fast access to a laptop, there is a dedicated 15\" side access laptop sleeve.
COMFORT & BREATHABILITY
Sweaty commutes and unpredictable days mean hauling gear for almost any situation, so we made ergonomic shoulder straps and a back panel able to contour to the shoulders and chest. All body-facing panels use multi-layer construction of durable and breathable fabrics to dissipate moisture and improve air flow.
MATERIAL TECH
For maximum durability and weather resistance, the ALPHA 31 is made of composite X51 (X50 for Multicam™) X-PAC™ fabric. These materials feature a Cordura® nylon face fabric laminated to 22º X-PLY™ reinforcement and polyester film for maximum stability and weather resistance. We also employ abrasion-resistant Tweave® fabrics as a durable, breathable barrier on body-facing panels. Learn more about our materials and tech.
WEATHER RESISTANT
All access points have been designed for weather resistance. The roll top uses a triple fold to lock out elements and all access panels feature water resistant rain flaps and YKK® Aquaguard® zippers.
