The Sea to Summit Silk Blend Sleeping Bag Liner has been developed precisely to improve thermal comfort inside the sleeping bag, increase heat retention and provide a much more pleasant feel on the skin. The combination of 72% Thermolite\u00ae Pro yarns with infrared technology, Thermolite\u00ae EcoMade fibres and 28% silk creates a soft, breathable and very comfortable sleeping environment.<\/p>\n<p>Many trekkers and campers report that this liner is clearly more comfortable than classic synthetic fibre models. The silk offers a soft, luxurious feel, while the Thermolite\u00ae fibres help maintain body heat and regulate the climate during the night.<\/p>\n<h4>Comfort and heat retention<\/h4>\n<p>Thermolite\u00ae Pro fibres use a hollow fibre structure similar to traditional Thermolite, but with permanent ceramic pigments. These absorb infrared radiation from the body and reflect it back to the wearer. In this way, body heat is utilised efficiently without making the material heavy or unbreathable.<\/p>\n<h4>Sustainable materials<\/h4>\n<p>Part of the fabric uses Thermolite\u00ae EcoMade, produced from 100% of recycled textile waste. These fibres are GRS certified and offer the same lightweight thermal performance and durability as new fibres, but with a significantly lower carbon footprint.<\/p>\n<h4>Hygiene and odour control<\/h4>\n<p>The liner is treated with HeiQ Fresh FFL, an effective biocide-free odour control technology. It uses a bio-based amino sugar polymer that neutralises body odours. On long journeys, pilgrimages or multi-day treks, this technology helps keep the liner fresh for longer.<\/p>\n<h4>Practical details for travelling<\/h4>\n<p>The rectangular version with Pillow Sleeve acts as a hygienic travelling sheet and includes a space to place the pillow. In addition, Comfort Stretch Panels along the seams increase sleeping comfort and allow for greater freedom of movement.<\/p>\n<h2>Highlights of the Sea to Summit Silk Blend Sleeping Bag Liner<\/h2>\n<ul>\n<li>Material mix with 72% Thermolite\u00ae Pro fibres and 28% silk for comfort and heat retention<\/li>\n<li>Infrared technology that reflects body heat back to the user<\/li>\n<li>Thermolite\u00ae EcoMade fibres made from GRS-certified recycled textile materials<\/li>\n<li>HeiQ Fresh FFL technology for biocide-free odour control<\/li>\n<li>Pillow Sleeve to integrate a pillow and improve hygiene during rest<\/li>\n<li>Comfort Stretch Panels along the seams for greater freedom of movement<\/li>\n<li>Suitable for trekking, camping, travelling and overnight stays in herbergen and hostels<\/li>\n<li>Sea to Summit lifetime guarantee<\/li>\n<\/ul>\n<h3>Sea to Summit Silk Blend Sleeping Bag Liner technical details<\/h3>\n<ul>\n<li>Weight: 160 g<\/li>\n<li>Length: 225 cm<\/li>\n<li>Packed size: 12 \u00d7 6.5 \u00d7 10 cm<\/li>\n<li>Material: 72% Thermolite\u00ae Pro \/ Thermolite\u00ae EcoMade, 28% silk<\/li>\n<li>Odour control: HeiQ Fresh FFL (biocide-free)<\/li>\n<li>Sustainability: Thermolite\u00ae EcoMade from 100% recycled textile waste, GRS certified<\/li>\n<li>Construction: rectangular shape with Pillow Sleeve and Comfort Stretch Panels<\/li>\n<li>Use: trekking, camping, travelling and overnight stays in herbergen and hostels<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>The <strong>Sea to Summit Silk Blend Sleeping Bag Liner<\/strong> combines high-quality silk with modern Thermolite\u00ae fibre technology, creating an extremely comfortable sleeping environment for trekking, camping and outdoor trips.
