{"product_id":"sea-to-summit-reactor-lightweight-liner","title":"Sea to Summit Reactor Lightweight Liner","description":"\u003cp\u003eBoost your sleeping bag's warmth without the extra heft. The Sea to Summit Reactor Lightweight Liner is your secret weapon for cosier nights. Its stretchy Thermolite® Pro fabric hugs your movements, while clever armholes let you sprawl out freely. The clever bit? Far Infrared (FIR) technology and hollow-core fibres work together to trap and reflect your body heat, cranking up warmth by up to 4°C without the bulk. Snap it into compatible Sea to Summit bags for a snug fit, or slip it into any sleeping bag. Built-in odour control keeps things fresh on long adventures, and it dries quickly too, meaning less laundry and a longer life for your beloved sleeping bag. Lightweight, versatile, and genuinely clever.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMax User Length:\u003c\/strong\u003e 170cm (Short). 185cm (Regular). 198cm (Long).\u003c\/p\u003e\n\u003cp\u003eBest Use For: Backpacking, Camping \u0026amp; Winter Camping.\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eFreedom to Move: Stretch-knit construction and armholes provide unrestricted comfort for any sleep position.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLightweight Thermal Boost: Thermolite® Pro with FIR and hollow-core fibres adds up to 4 °C | 7 °F warmth.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEasy to Clean: Quick-drying and machine washable with HeiQ Fresh odour control treatment.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCompatible Design: Fits all sleeping bags and snaps into Sea to Summit bags for secure positioning.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eProtects Your Sleeping Bag: Reduces washing frequency to maintain insulation loft and extend bag lifespan.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIdeal for backpacking, travel, hut stays, and warmer-weather adventures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSpecification\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eShape: Mummy\u003c\/li\u003e\n\u003cli\u003eAdded up to 4°C Warmth\u003c\/li\u003e\n\u003cli\u003eUser Length: 170cm (Short). 185cm (Regular). 198cm (Long).\u003c\/li\u003e\n\u003cli\u003eWeight: \u003cmeta charset=\"utf-8\"\u003e235g (Short). 255g (Regular). 260g (Long).\u003c\/li\u003e\n\u003cli\u003eStuff sack included\u003c\/li\u003e\n\u003cli\u003eMaterials: Thermolite Pro \u0026amp; Thermolite EcoMade\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"Sea to Summit","offers":[{"title":"Short (170cm)","offer_id":56768214335861,"sku":"SS-SN-SSRLWL-SHORT","price":38.95,"currency_code":"GBP","in_stock":true},{"title":"Regular (185cm)","offer_id":56768214368629,"sku":"SS-SN-SSRLWL-REGULAR","price":38.95,"currency_code":"GBP","in_stock":true},{"title":"Long (198cm)","offer_id":56768214401397,"sku":"SS-SN-SSRLWL-LONG","price":38.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1554\/2851\/files\/053203_ReactorLightweightSleepingBagLiner_Long-Mummy_Pewter_PRIMARY.jpg?v=1771601503","url":"https:\/\/rockrun.com\/fr\/products\/sea-to-summit-reactor-lightweight-liner","provider":"Rock+Run","version":"1.0","type":"link"}
