With an R-value over 6, the 10cm thick EtherLightXT Extreme air mat redefines lightweight sleeping comfort for winter adventures around the globe. Sea to Summit's Air Sprung Cells are the reason you will sleep better on this air mat. Each Air Sprung Cell deforms independently and allows the mat to conform to your body shape. This provides support and comfort by more evenly dispersing pressure across the mat’s surface. For the extra thick (XT) EtherLight design, many TPU loops are used to connect 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.

FEATURES

  • ASTM R-value 6.2 is designed for cold-weather use
  • Dual-density layers of THERMOLITE® insulation
  • Extra thick (XT) Air Sprung Cell construction for 10cm stable comfort
  • Lightweight, quiet and grippy 30/40D Nylon face fabric
  • Field repairable with included self-adhesive patches
  • Ultra-Fresh® anti-microbial treatment added to the TPU formula prevents internal mould growth
  • Pillow Lock attaches an Aeros pillow to mat

Awesome Boards….BUT the Smell!!!!
Color: Carbonized, Size: 3-piece
I’d love to give these 5 stars, they are heavy, well made, smooth, deep juice grooves, just nice….but the smell! I washed them, then used vinegar on them, set them outside over night, washed them again….its better but still present. I’d love some guidance on this. I’m hoping it goes away in a few days. It’s like a very strong woodsy smell that actually made my whole kitchen smell like these boards! Edit: Ok, here's what I did. Washed, let dry, coated and scrubbed with apple cider vinegar, set them in a high air flow area for 24 hours (I put mine outside on the patio over night), washed and scrubbed again, let dry, scrubbed with lemons and salt, let dry, washed again. Finally, there is still a slight smell if you push them against your nose but that seems to be fading as well. So, great boards if you want to go stubbornly go through the smell removal process. I don't think it's a chemical smell, I think it's processed bamboo that is shrink wrapped in air tight packaging too soon after manufacturing. Anyway, I'll move this to 4 stars....but lots of work involved here!

Don’t worry about the smell!
Color: Carbonized, Size: 3-piece
These are great for the price, though I’ve never had any desire or need to use the smallest one. They smell strongly of BBQ at first, but from what I’ve read that’s a natural result of a heat treatment used to increase it’s durability and dark color (the heat cooks the sugars in the bamboo which creates the scent). Anyways, I’ve had them for awhile now and the scent is long gone.
