Sea To Summit Ether Light XT Extreme Air Sleeping Mat

The Sea To Summit EtherLight XT Extreme Air Mat redefines sleeping comfort for winter adventurers, featuring an R-value up to 6 and a 10cm thickness due to their Air Sprung Cells technology. Each Air Sprung Cell is designed to independently adjust to the contours of your body, promoting even pressure distribution for improved comfort and support.

To reach the height of the extreme thickness (XT) EtherLight sleeping mat, many TPU loops are used to couple the top and bottom fabric layers to the Air Sprung Cell dot weld pattern. These loops allow the top and bottom layers to be positioned further apart which creates larger pockets of air when inflated—perfect for side sleepers.

This design also requires less fabric overall which means great stability and comfort for less weight. Dual-density layers of THERMOLITE insulation fill the Air Sprung Cells and work together to prevent convective heat transfer and boost warmth while remaining lightweight and packable. When the mercury drops, the EtherLightXT Extreme’s 6.2 (women’s 6.3) ASTM R-value will keep you cushioned and insulated from the cold hard lumps and bumps beneath.

Awesome

Lovely for a side sleeper, can't wait to try it in the cold.

Super compfy and warm

Love this mat for its comfort and warmth

Sleeping Mat

Used my Sea to Summit Ether Light XT Extreme Air Sleeping Mat last week in the NSW High Country.
The Mat performed well was more comfortable then expected, didn’t wake up sore .
The temp dropped below Zero at night the thermal layer did keep the cold from coming up through the ground .
Good advice from the Dudes at Past Outdoor .
Sound Purchase.

Great for all weather

Excellent piece of kit to have when out and about, really warm and comfortable particularly for side sleepers which is usually hard to find.

The only drink bottle you’ll ever need

The Nalgene needs no introduction. This bottle will serve you well for as long as you have it in your grubby little mitts. You will not be disappointed!

Nalgene Wide Mouth Sustain Water Bottle 1l

A great investment

We’ve had the Moondance 2FN for over 3 years. It’s held up in all sorts of weather and we are really impressed with its size and waterproofing.

Spyderco Rescue Knife 79mm Lightweight

Super lightweight

This is fit for purpose and super lightweight, which is the priority when hiking. Good product to stock and have available, quick delivery and nice packaging with a personalised note from the team.

Using a nalgene was risky business before buying this bad boy. Just remember to wash regularly.

Nalgene Wide Mouth Easy Sipper

Extra Water Carry

Took the 3L canteen on the Larapinta, was perfect for extra water carries when staying at high camp. Gravity fed from filter, the wide mouth is perfect and love that it stands up by itself so I could just leave it to do it's thing. 10/10

Nalgene Wide Mouth Cantene

Great Quality

I love these shirts & have had at least one since the start of PAST. They are thick, hold their shape well, and don’t shrink when laundered. This is typical of about all of PAST’s products - only top shelf gear.

Excellent

Absolutely love these Nalgene bottles. My previous 1 is at least 5 yrs old and still going strong. They don't leak, they are tough and a great all round drinking bottle at a fair price. Highly recommend

Arcade Adventure Capture Belt - Illusion

Reliable and easy to clean

This is my second BeFree filter as my first is nearing the 1000 litre limit. The flow rate is close to the advertised 2 litres per minute though I’m sure it will start to slow down after a few more uses as did my original. All in all, I like its functionality, ease of use and simplicity to clean. Pairs well with my CNOC 3 Litre bag.
