More on the Prize Package

The Sea to Summit Hamelin Synthetic Sleeping Bag: 15-Degree is a midweight, midsize, and comfort-rated down to 15 degrees Fahrenheit. It is part of the brand’s new Revive Sleep Range collection, a line of synthetic sleeping bags and self-inflating air mats crafted to be lighter, more packable, and have a lower environmental impact.

It is positioned for use on light treks and backpacking, yet versatile enough for use while car camping or on adventures in wet climates and cold conditions.

Sea to Summit’s relaxed mummy Contour Shape leaves enough room for side sleepers to move more freely. The bag has body-mapped sections of Revive Loft insulation for added warmth. Conversely, when temperatures rise, the bag’s Free-Flow full-length zipper with double sliders and short side zipper provide plenty of ventilation options.

The women’s-specific bag uses the brand’s Women’s Contour shape, which efficiently retains body heat and allows for natural sleeping positions, like on your side or in a figure-four. You can see the loftier build of the women’s specific bag in the specs.

The unisex Hamelin Synthetic Sleeping Bag (15 degrees) weighs 2 pounds, 11 ounces and has a compressed volume of 14L. The Hamelin Women’s Synthetic Sleeping Bag (15 degrees) weighs 3 pounds, 9 ounces, and has a compressed volume of 18.4L.

Both Hamelin versions are available as a 30-degree bag and in regular and long lengths. Additional features include the technical hood, draught collar and tubes, and a stuff sack.

These sleeping bags are made from Bluesign-approved recycled fabrics and are 1% for the Planet products.
