Heading out for a weekend hike or multi-day trek and worried about adding bulk to your pack? This ultralight mummy sleeping bag liner keeps you comfortable without the weight penalty. Designed for solo travellers and campers who value packability, it adds warmth to your existing bag or works as a standalone option in warmer conditions.
Why Customers Love It

Compact and Packable Design
Rolls down to a fraction of the size of a traditional sleeping bag, making it ideal for travellers with limited pack space. The included stuff sack keeps it compressed and protected during transport. Toss it in your daypack for overnight trips or keep it in your car for spontaneous camping.
Single Person Mummy Cut
The contoured shape follows your body's natural form, reducing dead air space that can make you feel cold. The tapered foot box keeps your feet snug, while the wider shoulder area allows comfortable movement. Suits most adults up to 185cm tall.


Durable Polyester Construction
Built from tear-resistant polyester that stands up to rough ground and repeated packing. The fabric breathes well to prevent that clammy feeling you get with cheaper liners. Reinforced stitching at stress points ensures it lasts season after season.

⭐⭐⭐⭐⭐
“Took this on a three-day hike through Wilson's Prom and it was perfect. Barely noticed the weight in my pack, and it kept me warm enough in my lightweight bag during those chilly April nights. Washes up easily too.”
“Use it in hostels when I'm travelling up the coast. So much better than sleeping directly in questionable bedding. Packs down tiny and dries fast after washing. Wish I'd bought one years ago.”
“Great for summer camping in Tassie when a full sleeping bag is overkill. The mummy shape keeps it snug without feeling restrictive. Also works brilliantly as an extra layer in winter when temps drop unexpectedly.”
“Lightweight and does exactly what it's supposed to. I've used it on beach camping trips and inland hikes. The stuff sack keeps it compact in my car's emergency kit. Good value for what you get.”
