The Shralpinist Stretch Bibs are built for mountain explorers who need storm proof bibs that are designed for dynamic movement. New for 2024, the bibs are made out of stronger 100% recycled 4-way stretch 30K/30K 70D fabric that offers the same soft feel and stretch, but improved durability. The Shralpinist Stretch Bibs are high performance and responsibly made bibs that will keep you warm, dry and moving at maximum efficiency through any terrain.
