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.

Nice pants.
Color: Deep Gray, Size: 10
These are nice pants for a boot to wear to a formal event. I got these for my son to wear to a wedding. They fit him good and he said they were comfortable. The material seems decent for the price. He wore them one before out growing them but that is expected with kids.

Baggy hips
Color: Light Gray, Size: 6, Color: Light Gray, Size: 6
These gray dress pants don't fit perfectly but the size range it so wide that it's expected. My 5yr old is tall for his age but he's thin with a small waist. Pants made with adjustable waists are ideal if we get them long enoughlike a 6 or 7. There biggest flaw in these pants is that the sides (or thigh areas) are so baggy the form a weird pouch. Much like most pants heel probably outgrow the length before he can fill in the hip and waist areas. Other than that, the color is a soft gray. The material is thin but it irons quickly. It's overall quality used fair so if your kid is average height and weight, this might fit perfectly.

Dressy without the struggle
Color: Deep Gray, Size: 7
These are really nice little dress pants for boys. Perfect for church, weddings, or anything where they need to look a bit more put together. The big win for me… they’re not stiff. My kid didn’t fuss about wearing them at all, which says a lot. They look clean and polished but still have some comfort to them, which is exactly what you want for this kind of thing. They also seem pretty well made, nothing fancy but solid for the price. Easy win if you need dress pants a kid will actually wear.
