The Sea To Summit Hamelin Sleeping Bag -9°C 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 (mummy) shape offers room to move in any sleeping position. Layers of Revive Loft are strategically placed to maximise insulation value.

In warmer weather, the Free-Flow full-length zipper with double zipper sliders allows you to open the side in either direction or across the foot. You can also open the Hamelin completely flat for use as a quilt. The short 2-way right zipper creates a fully customisable ventilation system.

Go hard but rest easy knowing that the fabrics and Revive Loft insulation are RCS-recycled and bluesign approved. Your purchase also gives back, with 1% of each Hamelin Sleeping Bag sale supporting 1% for the Planet® partners preserving biodiversity.
