Heyburn 3L Bib

The Heyburn Bib is a high-performance, lightweight 3-layer shell engineered for demanding backcountry conditions, featuring a 30k/30k waterproof and breathable membrane and PFAS-free DWR to keep you dry no matter how crazy the snow globe’s going. Designed with a streamlined, function-first approach, it’s made with a soft yet durable 100% recycled nylon paired with a NASA-developed Trizar® ™ backer that reflects body heat when you're cold and release excess heat when you're working hard—keeping your temp just right all day long. A stretch panel at the back improves comfort and fit, while light mechanical stretch throughout ensures you can move freely on the skintrack or descent. Thoughtful features include side leg zips for easy venting and drop-seat access (and for peeing in the wild), a thigh pocket with internal beacon attachment, and a chest zip pocket with low-profile key clip for secure, bounce-free storage. The ergonomic silhouette is designed by women, for women - and all the ways we move. SIZING NOTE: WE RECOMMEND SIZING DOWN ONE SIZE. But if it’s not right the first time, we offer free exchanges.
