Built With America's Oldest Mountain Rescue Team
To create a lightweight, nimble USA-made hiking boot that can stand up to extreme conditions, Danner collaborated with the Crag Rats — America's oldest search and rescue organization, based in Hood River County, Oregon. The Crag Rat Evo has a GORE-TEX® liner for waterproof protection, and the engineered synthetic leather and textile upper features highly breathable, abrasion-resistant Perspair® side panels. An insulated Aerogel toe cap and crampon-compatible TPU heel clip keep you moving in very low temperatures.
Key Features of the Danner Crag Rat Evo 5.5"

Synthetic Leather & Perspair® Upper: PU-coated nylon thread woven into the side panels creates a material that's extremely lightweight, breathable, and durable.
