Mammut’s Sender IN Vest Women adds a sleeveless thermal layer for everyday outings and hikes in transitional weather. Its LOOPINSULATION filling focuses on retaining warmth around the core while leaving the arms free to move.
The synthetic filling is made entirely from recycled materials, with equal shares of industrial rope-production offcuts and recycled PET. Mammut pairs this with a recycled-polyester lining and an outer fabric containing recycled polyester and stretch fibres.
Two zipped side pockets provide storage, and a partially elastic hem helps the vest sit comfortably in place. The regular-fit design is listed at 380g. For walkers assembling layers for cooler days, it offers an insulated option that can be combined with a separate shell when conditions call for additional protection.
