Whisper is an ultralight, inflatable camping mat that delivers packable warmth and comfort for 3-season camping. Made with 35% post-consumer recycled materials.

It's got an r-value of 2.5 which puts its insulation performance closer to that of a self-inflating mat but maintains the lightweight, packability of an inflatable mat. We've used Thermolite T3E TL Ecomade insulation, from the same family used in our Cloud Peak sleeping bags, for its high loft and excellent warmth-to-weight ratio.

Whisper weighs only 820g and can be inflated using its stuff sack which reduces condensation and keeps the fill working better for longer.


Integrated pump sack

Stuff sack doubles as a pump to inflate your mat. This keeps moisture out of the mat and maintains the performance of the fill.

Compact warmth

Thermolite® Ecomade insulation offers the warmth of a self-inflating mat without the bulky foam giving a much more compact pack size

Ultimate sleep comfort

7cm thick with a wider profile at the shoulders and hips gives a great night's sleep for back or side sleepers

Recycled materials

100% recycled Nylon outer fabric and a 35% recycled thermal insulation

We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.
