Why Customers Love It

Mummy Shape for Maximum Efficiency
The tapered mummy design follows your body's contours, eliminating dead air space that saps warmth. This shape also reduces fabric weight compared to rectangular liners, making it the smart choice for ultralight backpackers tackling the Great Ocean Walk or Grampians Peaks Trail.
Packs Down to Nothing
Compresses into a stuff sack smaller than a water bottle, freeing up precious pack space for food and gear. Whether you're doing a weekend trip to the Blue Mountains or a week-long expedition in Kakadu, this liner won't eat into your luggage allowance.


Quick-Dry Polyester Construction
Polyester fabric wicks moisture and dries fast, crucial for humid Queensland nights or dewy mornings in the Snowy Mountains. Unlike cotton liners that stay damp, this one's ready to pack up after breakfast, keeping your load light and dry.

⭐⭐⭐⭐⭐
“Took this on the Overland Track and it was a lifesaver. Added just enough warmth on those freezing Tassie nights without adding bulk to my pack. Dried out quickly after a dewy morning at Cradle Mountain. Highly recommend for serious hikers.”
“Perfect for my solo camping trips around the Sunshine Coast. I use it on its own in summer and it's plenty comfortable. Packs down so small I barely notice it's there. Easy to wash after sandy beach camps too.”
“Bought this for a week-long hike in the Walls of Jerusalem and it performed brilliantly. The mummy shape kept me warm when temps dropped below zero. At 300g, it's lighter than my water filter. Worth every cent.”
“I've used this in hostels across WA and on camping trips down south. Super versatile—keeps dodgy hostel sheets off me and adds warmth when I'm swag camping in the Pilbara. Dries fast after a quick rinse. Love it.”
