Military Modular Sleep System – All-Season Convertible Sleeping Bag|Traverseon

Two Ways to Rest. One Bag to Share.

The Traverseon All-Season Convertible Sleeping Bag is designed to adapt like a military modular sleep system, giving you comfort and flexibility in any season. At night, just unzip and rest with the built-in pillow hood, while the high-loft hollow fiber fill expands to wrap you in warmth. Unlike cotton fill, it stays fluffy and dry even after damp nights.

Choose your weight: from a 0.7 kg ultralight summer sleeping bag to a 2.4 kg alpine-grade cocoon, each rated for comfort from 25 °C down to −10 °C. The 170T ripstop shell blocks wind and dew, while the soft lining feels like cotton sheets against your skin.

Zipped up, it’s a cozy insulated sleeping system; opened flat, it converts into a quilt for sharing. A true 4-season convertible sleeping bag, it makes camping feel less like roughing it and more like bringing home into the wild.

• All-Season Temperature Control — Sleep Right, Not Too Hot or Cold
  From ultralight 0.7 kg summer bags to alpine-ready 2.4 kg builds, each model is precision-tuned for the right warmth (Comfort: 25°C→0°C / Limit: 20°C→−5°C / Extreme: 15°C→−10°C). Zoned insulation keeps core heat where your body needs it most—no wasted bulk, no overheating.
• Convertible Comfort — Blanket, Mat, or Shared Bag
  One zip, many options. Fully unzip for a flat quilt or picnic mat, zip two bags together for shared warmth, or layer with liners in colder months. Perfect for vanlife, guest nights, or backyard lounging.
• Stable Loft Insulation — Warmth That Doesn’t Collapse or Shift
  Unlike cheap fills that clump, the hollow-fiber matrix traps air channels for lasting loft. Lab tests show 85% loft retention after repeated packing and washing, keeping heat steady even in damp, misty camps. Segmented baffles prevent shifting, so every inch stays warm.
• Spacious Freedom — Moves With You, Not Against You
  Rectangular cut fits users up to 6'2", with added footroom for hot sleepers. Side-sleepers and restless movers can roll without squeeze. Dual zippers + anti-snag guard let you adjust airflow one-handed in the dark. Even kids or first-timers can handle it easily.
• Built-In Pillow Pads — No More Forgotten Gear
  The integrated hood creates a raised pillow zone that cushions your neck and seals in warmth. Just unzip, lie back, and rest—no need to pack a separate pillow, no neck strain after a long day outdoors.
• Weather Shield Outside, Bedsheet Comfort Inside
  170T ripstop shell with water-repellent finish blocks wind, dew, and tent condensation, while the brushed anti-static lining feels soft and breathable against skin — even after sticky summer days. Durable enough to resist trail abrasion.
• Drawstring Hood — Instant +2–3°C Warmth Boost
  Cinch tight on cold nights and create a sealed micro-climate around head and shoulders. Prevents those 3 a.m. cold-neck drafts that ruin sleep.
• Compression Sack — Smaller, Faster, Smarter Pack
  Packs down from 42×28 cm to 32×20 cm depending on fill. Pre-shaped compression design reduces repack time by 20% — no wrestling or forcing. Compact enough for trunks, closets, or emergency kits.
• Colors That Work in the Wild — Easy to Spot, Easy to Share
  Four classic shades (Army Green, Navy, Red, Blue) make it easy to ID in group camps. Neutral, dirt-concealing tones fit any setup.
