The bluesign® certified shell and lining fabric, and almost all components of this sleeping are made from 100% recycled polyester. ThermoStretch seams, 360° distribution of high-loft hollowfiber fill and shingle construction with 1.3x overlap give this bag excellent sleeping comfort. Practical details like an anti-snag zipper guard and ergonomic foot box together with the hardwearing functional shell fabric make this a lightweight, functional option for mountain use.
