Gecco 400

Gecco 400


Gecco 400 is a mid-weight down insulated sleeping bag in our range of bags produced using eco friendly materials. It is designed for year round use in the outdoors and offers a higher degree of cold protection than its Gecco 250 little sister. Both have an outer shell made from the unique Yeti eco friendly shell fabric of plant based nylon extracted from the Ricinus plant. The fabric has a very soft feel and the lining fabric made of 100% recycled polyester is both soft and adds to the insulation power.
