Will the KOALA 2.0 damage my clothes/jacket/gear?

The KOALA clamp is extremely grippy yet non-marring for most fabrics. It's designed to work with outdoor fabrics like Cordura™, denim, Gore-Tex™, fleece, cotton, etc. without leaving a mark. We've tested it on our own gear including packs, shell jackets, mid-weight liners (wool), PFDs, and more without issue.
