Ether Light xt Insulating Mat Rectangular


Lightweight, warm, and incredibly comfortable, the Sea to Summit Ether Light XT Insulated Mat is perfect for trips year-round. This rectangle version gives you 9cm more width down the length entire mat compared to the regular tapered version preventing those annoying slips off the mat in the middle of the night! 

With a market leading 10cm of cushioning the Ether Light XT insulated is perfect for side sleepers that would otherwise wake up with numb shoulders and hips as its large air pockets created from looped TPU baffles let your body from can sink in without touching the ground. To help keep you warm, this has THERMOLITE® insulation and Exkin Platinum® to reflect radiant heat. This mat is from a 30/40D nylonfabric which provides a grippy and durable surface that’s also field repairable with included adhesive patches. 

Deflate and adjust your mat easily with the multi-functional high flow rate valve, and inflate it efficiently with the Airstream™ Pump integrated into the stuff sack. To prevent mould growth, there’s an anti-microbial Ultra-Fresh™ treatment and it’s simple to attach a separate Aeros™ pillow as there is a hook and loop PillowLock™ system to prevent it from slipping.

"I spent close to 3 hours in this store today, being fitted for and choosing a pack, and the staff are fantastic. Helpful, knowledgeable, patient and friendly - and I think I'm probably a fussy customer and I have difficulty finding packs that fit comfortably. Has to be my best experience in this kind of store to date."

"My favourite outdoor shop in Sydney. This is where you go if you want to see gear stocked because of it's quality, not just because it's corporate overload has pumped out another 10,000 puffer jackets that need to be moved before next season. Knowledgeable staff that actually partake in trekking and travelling themselves. Definitely worth dropping in!"

"Always friendly, helpful staff with great knowledge. Great range of good quality products (nothing really low end) including Australian/NZ brands e.g. Wilderness Equipment, One Planet and Aarn. Never had a fuss with exchanging unused gear within the 2 week period."
