Warm and light
"Loved the new jacket, light and warm."
Lightweight, breathable, and reliable even when wet, Mammut LOOPINSULATION jackets are built with 100% recycled insulation from industrial rope production offcuts and recycled PET. Made to keep warmth close through shifting temperatures.
Polyester-based rope offcuts from industrial rope production are gathered – materials that would otherwise be discarded.

These offcuts are then untangled into single strands which are brushed together and combined with recycled plastic.

The end result is fluffy polyester sheet padding and cluster fill, which creates warming insulation for our jackets.

"Loved the new jacket, light and warm."
"Mammut produced another cutting edge jacket. I purchased the Crag IN jacket and I can’t be more impressed. The size is true to fit and unbelievably warm. A very impressive feature of the jacket is the weight. The coldest temperature I wore the jacket was +10 and was very comfortable. I highly recommend this jacket."
"There's just a hair too much room inside for me. But it's okay. It fits. I ordered medium. I'm 5'8 and my weight is 140lbs"
"Super Passform, angenehm zu tragen"
"This is a great medium jacket or mid layer. It fits great, lightweight enough, not too bulky or thin. Color true to photos. Size large fit me great as 5'10" 180 lbs athletic build."
"Leicht und trotzdem warm, auch wenn es sehr kalt ist. Passt wie angegossen."
"Gute Verarbeitung und gutes Design"
"Nicest puffy I've ever owned!"
"Chaude, mais un peu trop volumineuse"
"Perfect for skiing over a base layer and u see a shell. Be mindful of size."
