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

Synthetic Leather and Perspair® Upper - The synthetic leather upper has side panels made of Perspair®. PU-coated nylon thread is woven to create a material that is extremely lightweight and breathable while remaining incredibly durable.

GORE-TEX (GTX) - 100% waterproof and breathable, GORE-TEX liners ensure that no water gets in, while allowing sweat and moisture to get out.

PrimaLoft® Aerogel Toe Cap - Used by NASA to insulate space suits, Aerogel is the world’s lightest solid comprised of more than 95% air. This toe cap provides superior insulation with minimal bulk or weight and doesn’t pack down over time.

Removable OrthoLite Footbed - Three layers of varying density are combined for maximum cushioning and support. The entire footbed is made of open-cell polyurethane for better heat dissipation and air circulation.

Vibram® Mulaz Outsole - The Mulaz outsole is made of a sticky rubber compound that provides optimal traction on rock, snow or mud while providing support and durability in extreme environments.

Crampon Compatible - The semi-rigid heel clip is crampon-compatible and is built to handle extreme temperatures and icy conditions.

TPU Mudguard - LIBA® Smart TPU mudguard offers increased durability without adding weight.
