The Women’s Hamelin is a women’s-specific, performance-oriented synthetic sleeping bag
Designed for comfort in the backcountry, it offers variability across climates and wet and dry conditions. The weight-efficient Women’s Contour shape allows for natural sleeping positions – on your side, in a figure-four – the women’s Hamelin cradles you in comfort. In colder conditions, the strategically placed layers of Revive Loft insulation will keep you cosy. As the temperature warms, the Free-Flow full length zipper with double sliders and short side zipper provide variability and customisable ventilation. bluesign-APPROVED, RCS recycled fabrics and Revive Loft insulation let you tread lightly, whatever your pursuit. The Women’s Hamelin is one of the 1% for the Planet products.
Revive Loft
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 the synthetic sleeping bags, you can tread hard on the trail, and Revive Loft lets you tread lightly on the planet.
RCS Recycled Fabric
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.
Engineered for Women
The 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.
Free Flow Zip
The 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.
