Your holy grail for fast-and-light 2–3 season adventures. Every single gram has been optimised to deliver one of the lightest full-sized sleeping bags available. The Zero SL is powered by 230g of premium 1000+ loft RDS goose down and tips the scales at an incredible 417g. With a comfort rating down to 2°C and an XL length that suits users up to 6'8\" (203cm), it punches far above its weight.\u003c\/p\u003e\n\u003cp\u003eBuilt for bikepackers, hikers, and ounce-counters who refuse to compromise, the Zero SL excels wherever space and weight matter most. Its tiny pack size and featherlight build make it a versatile addition, use it solo for ultralight missions, pair it with another bag for extra warmth, or keep it in your pack as a reliable “just in case” layer for unpredictable trips.\u003c\/p\u003e\n\u003cp\u003eCrafted from Mont’s advanced Anti-Gravity Nylon, the Zero SL achieves remarkable performance with minimal bulk. This ultralight fabric allows the down to loft freely and fully, delivering superior warmth with less fill, meaning more comfort, less weight, and unmatched efficiency on every adventure.\u003c\/p\u003e\n\u003cp\u003eComfort Temperature Rating for warm sleepers: 2°C, \u003cmeta charset=\"utf-8\"\u003ecold sleepers: 8°C.

Radial Arc baffles curve naturally around your body rather than compressing the down around your body.\u003cbr\u003eWhen a down baffle (chamber) is bent, ripples in the fabric occur, which will create cold spots and compress down. The radial Arc Baffle System reduces distortion and increases warmth and loft.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTOASTER POCKET\u003c\/strong\u003e: is for slow-release, air-activated heat packs: your toes and feet will never be cold again. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEXCEPTIONAL PACKABILITY\u003c\/strong\u003e: packs down to the size of a 1-litre bottle.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/BDQupEnAxN4?si=E1LQH3twqgIs-qDL\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMore Help?\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFor further assistance on choosing your down sleeping bag, we have an article explaining fill power, the pros and cons of down over synthetic insulation and more info on caring for your bag available to view \u003cspan\u003ehere: \u003c\/span\u003e\u003ca title=\"Article: A guide to down sleeping bags...down explained\" href=\"https:\/\/rockrn.com\/blogs\/the-flash-rock-run-blog\/a-guide-to-down-sleeping-bags-buying-guide\"\u003eA Guide to Down Sleeping Bags\u003c\/a\u003e\u003cspan\u003e.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePerfect for Bike Packing, Ultralight hiking, or as an extender layer\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eVertical baffles on the torso maintain optimal down distribution\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eContoured hood for increased warmth\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMade with Anti-Gravity Nylon inside and out, one of the World's lightest downproof\u003c\/li\u003e\n\u003cli\u003eNylon: 7 denier with mini rip-stop, a thread count in excess of 520, double heavy cire downproof treatment.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e240g (Standard) and 260g (XL) of 1000+ loft 98\/2 Premium White RDS goose down with water-resistant DWR Loft treatment\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e1\/2 side zip using ultralight YKK #3 Zip weighs only 4grams\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMini-baffles with sewn through construction\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSewn with hydrophobic Epic thread to prevent moisture from wicking along seams and inside the shell\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIncludes ultralight Nylon stuff sack \u0026amp; large storage sack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIntended use: Ultra Light Hiking\/backpacking\u003c\/li\u003e\n\u003cli\u003eSeason Rating: 2-3 Season\u003c\/li\u003e\n\u003cli\u003eMaximum User Height: Women: 170cm \/ Standard: 200cm \/ Long: 200cm\u003c\/li\u003e\n\u003cli\u003eCold Sleeper Comfort Temp: 8°C\u003c\/li\u003e\n\u003cli\u003eWarm Sleeper Comfort Temp: 2°C\u003cmeta charset=\"utf-8\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eDown treatment: Water-resistant DWR Loft treatment\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMax Shoulder Circumference: \u003cmeta charset=\"utf-8\"\u003eWomen's: 160cm \/ Regular: 160cm \/ Long: 170cm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInsulated collar: No\u003c\/li\u003e\n\u003cli\u003eShell Fabric: Ultralight Anti Gravity Nylon\u003c\/li\u003e\n\u003cli\u003eLining: 100% recycled ultralight silk-touch 15 denier downproof Nylon\u003c\/li\u003e\n\u003cli\u003eFilling: Premium white goose down\u003c\/li\u003e\n\u003cli\u003eFill power: 1000+\u003c\/li\u003e\n\u003cli\u003eWeight: Regular: 1000g \/ Long: 11600g\u003c\/li\u003e\n\u003cli\u003eFill Weight: Regular: 230g \/ Long: 260g\u003c\/li\u003e\n\u003cli\u003eCompression Size: 12x26cm(standard) \/ 12x26cm(Long)\u003c\/li\u003e\n\u003cli\u003eZip: : Left\u003c\/li\u003e\n\u003cli\u003eZip Configuration: Ultralight 1\/2 length side zip\u003c\/li\u003e\n\u003cli\u003eColour: Shadow\/Black\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCut: Mummy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"MONT","offers":[{"title":"Regular","offer_id":56392000569717,"sku":"SS-DB-MZEROSL1000-REG","price":323.0,"currency_code":"GBP","in_stock":false},{"title":"Long","offer_id":56392000602485,"sku":"SS-DB-MZEROSL1000-LONG","price":350.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1554\/2851\/files\/ZeroSL-closed_e13ca018-f93d-4461-a1f7-731df5948109.jpg?v=1785447611","url":"https:\/\/rockrn.com\/products\/mont-zero-superlight-sleeping-bag-2-c","provider":"Rock+Run","version":"1.0","type":"link"}
