Sea To Summit Womens Ether Light XT Extreme Mat Regular Black

What isthe Ether Extreme Insulated Sleeping Mat?

You may already be familiar with Sea to Summits 3-Season Ether Lite Sleeping mat, well this is their warmer version! Sea to Summit have increased the insulation to make the matt warmer for cold-weather adventures.

This innovative mat is perfect for backpacking, travelling, and mountaineering in sub-zero conditions thanks to the super warm Exkin Platinum, dual-density layers of Thermolite insulation, exceptionally comfortable Air Sprung Cell construction and the ability to deflate and inflate the mat quickly. The Ether provides a luxurious10cm of thick cushioning whilst still maintaining a tiny pack size.

What isthe Ether made of?

Insulation: Inside the mat, you'll find a super warm dual-density Thermolite and Exkin Platinum insulation to provide enough warmth for winter seasons. Exkin Platinum reflects your natural body heat back to you, while Thermolite insulation prevents convective heat loss over time. If that wasn't enough, the Ether Extreme includes an anti-microbial treatment to avoid future issues when warm, moist air inevitably becomes trapped inside.This insulation is not only warm but incredibly packable, meaning the sleeping mat will roll down to a fraction of its blown-up size.

Outer Fabric: The mat is made using a combinationof lightweight, quiet and grippy 40D and 30D Nylon fabric. The combination of these two weight of fabric give you a mat that will pack down to almost nothing, almost weighing less than a 500ml bottle of coke, but also gives you extra protection and reassurance when the ground underneathyou is a bit harsher thenyou'd like.

What are the features?

Providing further comfort is Sea to Summit's eXtra Thick (XT) Loop Baffle Air Sprung Cell technology. Larger air pockets are created by using many looped TPU baffles which connect the top and bottom fabric layers with their Air Sprung Cell dot weld pattern. The looped baffles allow the top and bottom layers to be positioned further apart creating larger pockets of air when inflated that require less fabric overall.

This design, in addition to the extra height of this mat that lets hips sink deeper into it without touching the ground, is perfect for those of us who sleep on our sides. Other features include a repair kit, an anti-microbial treatment to prevent mould growth and a pillow lock to attach an Aeros pillow in place.

What is the R-value?

This matt has a whopping R-Value of 6.2 which in real terms means that this matt will protect you in extreme, expedition-level sub-zero conditions.R-Values are an international standard of insulation and (in simple terms) indicate the materials ability to reduce heat flow through conduction, radiation or convection. Therefore the higher the R-Value, the lower the heat transfer and the greater the insulation properties of the material.
