Product Details

Designed for adult hikers and campers, the Ultralight Waterproof Sleeping Bag offers a compact, 4-season envelope-style solution for outdoor nights. It balances warmth, durability, and packability for trekking and backpacking trips where every gram matters.

Key Features

  • Lightweight and compact: weighs around 0.8 kg and includes a compression bag; two tightening straps reduce volume, making it easy to fit in a daypack or multi-day kit.
  • Durable, weather-ready shell: 190T tear‑proof polyester with a waterproof outer layer to resist damp ground and light rain; hollow cotton filling provides warmth while remaining breathable.
  • Breathable, skin-friendly lining: inner 190T polyester pongee offers a soft feel against skin and helps regulate moisture during sleep.
  • Flexible temperature range: designed for summer nights over 25°C and spring/autumn conditions around 10–20°C; winter usability can be achieved with layering and venting features such as the bottom zipper.
  • Versatile and expandable: envelope design can be spliced with another bag to form a double sleeping bag; bottom zipper aids ventilation and foot movement for comfort.
