Hamelin Womens Synthetic Sleeping Bag

Engineered to insulate even when wet, Revive Loft is a synthetic insulation made of 100% RCS-certified, post-consumer recycled, multi-Denier polyester. The fibres are hollow-core to trap more insulating air, and the three different Denier weights of fibre provide softness and durability.

Used in our synthetic sleeping bags, you can tread hard on the trail, and Revive Loft lets you tread lightly on the planet.

Fabrics or materials used in these products are certified as recycled according to the Recycled Claim Standard. RCS is an international, voluntary standard that uses the ISO definition for 'recycled'. It sets criteria for third-party certification of recycled input and ensures responsibility throughout the supply chain.

Sea to Summit considers environmental impact in its choice of materials, and recycled materials are chosen only when they meet appropriate performance and durability levels.

Our women's specific sleeping bags feature a distinctive shape designed to provide more comfort and optimum thermal efficiency. The designs are ideally suited to a woman's shape - slightly narrower in the shoulders and roomier between the hips and knees. Insulation distribution is strategically matched to ensure the torso and the foot areas are kept toasty warm.

Our Free Flow zip design ensures your sleeping bag retains maximum warmth when needed and offers multiple ventilation options in warmer temperatures. The half-zip on the right side of the bag (left side on women’s bags) provides freedom of movement for both arms, offers additional ventilation and allows the top third of the bag to be folded down.

Most Free Flow sleeping bags can be opened completely flat as a quilt.
