Traverseon 1P All-Season Ultralight Washable Envelope Sleeping Bag

Lighter Than a Water Bottle, Built to Wash and Go
The Traverseon Ultralight Washable Envelope Sleeping Bag packs lighter than a water bottle yet provides full-body comfort wherever you go. Weighing just 680g for the standard warmth version or 760g for the extra-warmth option, it slips easily into a daypack, pannier, or car trunk. It unzips flat into a quilt for vanlife, stargazing, or a quick guest bed. The 380T ripstop shell sheds dew and spills, while the soft brushed lining feels cool and breathable against your skin. When the trip ends, toss it in the washing machine—no hand-washing, no special care. Always fresh, always ready. From misty mornings in camp to spontaneous overnights on the road, it delivers warmth, comfort, and simplicity in one compact roll.

• Ultralight and Compressible: 680g for Light Warmth / 760g for Extra Warmth
  Lighter than a standard water bottle, this bag delivers full-body coverage without bulk. The 680g version is designed for warmer weather, while the 760g version offers extra warmth for cooler conditions. Both versions compress to 29×12 cm (680g) or 31×13 cm (760g)—about the size of a rolled-up hoodie. The reinforced Oxford compression sack cuts volume by 60%, making it perfect for ultralight packs, bikepacking kits, or car trunks.
• WashCycle™-Ready Comfort — Machine Washable, Skin-Friendly Inside
  No hand-washing, no special detergent. Built to handle repeated machine washes, the shell, liner, and fill stay stable trip after trip. The brushed 210T pongee lining feels smooth and breathable, gentle even on sensitive skin—comfort that’s effortless to clean.
• Breathable Insulation for 15°C Comfort, -3°C Survival
  Hollow-core synthetic fill locks in warmth like alpine-rated systems. Comfort-rated to 15°C, with safe survival down to –3°C when paired with base layers. Use solo in summer or layer inside a down bag for frosty mornings—extra warmth without extra weight.
• Dual-Use Design: Sleeping Bag or Lay-Flat Blanket
  At 190×75cm, it zips for full coverage or unzips flat into a quilt or mat cover. Stretch out in rectangular comfort, or lay it open for stargazing, beach lounging, or covering seats in transit. One bag, many uses.
• Durable 380T Ripstop Nylon Shell with DWR — Lightweight Weather Resistance
  Made from high-density 380T ripstop nylon for abrasion resistance and long-term strength. A durable water-repellent coating sheds dew, spills, and light rain while staying breathable—keeping you dry without feeling clammy.
• Sealed Warmth & Windproof Durability — Closure That Locks Heat In
  Dual-direction zippers with anti-snag guards and a Velcro neck guard seal warmth in and keep drafts out. Reinforced seams and dense stitching block wind and boost structural strength for reliable performance in rugged conditions.
• Nature-Inspired Colors
  Ready for everyone, ready for anything—simple handling and lightweight build make it a versatile choice for kids, seniors, or guest nights at home. Also reliable as an emergency backup—always ready for parks, picnics, or unexpected overnights.
• Smart Value Without the Bulk
  Delivers the comfort and flexibility of premium bags at a fraction of the bulk and cost. Whether backpacking, car camping, or preparing for the unexpected, it covers more ground with less gear.
