Revive Loft: is a synthetic insulation made of 100% RCS-certified (Global Recycled Standard), post-consumer recycled, multi-denier polyester that is engineered to insulate even when wet. The fibres are hollow-core to trap more insulating air, and the three different Denier weights of fibre provide softness and durability. Used in Sea to Summit's synthetic sleeping bags, you can tread hard on the trail, and Revive Loft lets you tread lightly on the planet

bluesign® approved: bluesign® is the world's strictest textile standard for environmental and consumer protection in textile production, a system that provides safer and more sustainable environments for people to work in and everyone to live in. Every item that has the bluesign® approved label has been manufactured and recognised in accordance with the bluesign® standard and, therefore, produced in a resource-conserving way, with the highest level of consumer safety and a reduced impact on people and the environment (including factors such as worker health and safety, approved chemicals, carbon emission, water consumption and energy consumption).
