Hamelin Synthetic Sleeping Bag The Hamelin is a performance-oriented synthetic sleeping bag designed for comfort. Built for the backcountry, it is at home in a range of climates and conditions – especially when things turn damp. The weight-efficient Contour shape offers room to move in any sleeping position, while Layers of Revive Loft are strategically placed to maximise insulation value. The Free-Flow full length zipper with double sliders and short side zipper provide variability and customisable ventilation. Go hard but rest easy knowing that the fabrics and Revive Loft insulation are RCS-recycled and bluesign-APPROVED. The Hamelin is one of our 1% for the Planet products.
