When you need superior insulation in a lightweight package, this resilient sleep mat balances maximum warmth with minimum weight for a comfortable night’s rest wherever your journey takes you.

Lightweight and compact, the Stratosphere 5.5 boasts a superior warmth-to-weight ratio, making it a versatile all-mountain sleep mat which is highly insulating yet has a small enough pack size to take on all your trekking, climbing and backpacking adventures.

Stratosphere 5.5

This sleeping mat has lived up to expectations. It was put to use 2 winter weekends in a row, its easy to inflate with the air bag that comes with it, and for a change it actually fits back into the the bag it comes in without a fight. It is comfortable for a 100kg side sleeper like me.

Awesome Mat

Perfect mat for winter hiking, The R rating makes it very comfortable in freezing weather, and as I am 6ft and wide, the XL size was perfect for me.

Great Sleeping Mat

Only a few nights, but it has held up great and is really comfortable. Wish it came with a bigger stuff sack to stuff the mat in after use, other then the pump sack. Overall, great comfy mat.
