⚡ At a Glance
- • Thermal Performance: 150gsm microfleece delivers warmth comparable to a 1-2 season sleeping bag when used appropriately
- • Best for: Backpackers and campers seeking extra insulation that remains lightweight and compact
- • Not ideal for: Users who need double or large sleeping bag coverage, since size matches single envelope bags
Envelope-shaped liner measures 220cm by 80cm with an integrated hood and two-way L-shaped zip. Packs down to a 32cm x 15cm x 15cm drawcord bag, weighs 513g and is machine washable.
Extra Warmth – with 150gsm microfleece
150gsm microfleece traps air close to the body, reducing heat loss through convection and retaining more warmth than a bare sleeping bag shell. The material offers a high warmth-to-weight ratio similar to light seasonal insulation.
Using the liner inside a 3-season sleeping bag can transform the bag into a 4-season option, making colder-night camping more feasible.
Temperature Control – with two-way L-shaped zip and hook-and-loop closure
A two-way L-shaped zipper enables openings from multiple points to regulate airflow, while a hook-and-loop strap secures the zips to prevent heat escape when closed. The L-shaped design also allows the liner to lie flat.
Campers can vent quickly when warm or seal up tightly for retained heat, and the liner doubles as a blanket when opened flat.
Lightweight Packability – with compact drawcord bag and 513g packed weight
Drawcord storage reduces bulk to 32cm x 15cm x 15cm and the packed weight of 513g keeps overall rucksack load light. Microfleece construction balances insulating ability with minimal heft.
The liner serves as a practical, lightweight alternative to carrying a full sleeping bag in warmer conditions and is easy to wash between trips.
