TETON BROS. HPPE Over Hoody, Size M I took it to the backcountry about 5 times, but I actually wore it twice. I'm selling it because I no longer have the opportunity to use it. I couldn't find any stains or fraying, but I cut off the tag because of my preference. It's in beautiful condition, just without the tag. Thank you very much. The following is a product description. When resting or waiting in the snowy mountains, if you take off your shell and try to put on a mid-layer, your body will cool down in no time. So, what do you do? The TETON BROS. way is to wear the shell and then layer insulation over it. This is an insulation with synthetic fiber filling designed for such situations. It's one size larger to be worn over a shell. The cuffs can be widened with a zipper, so you can put it on smoothly even with gloves on. The filling is a mix of "PrimaLoft ThermoPlume," which has a down-like shape, and aerogel, which has high insulation properties. The outer fabric is HPPE (High Performance Polyethylene) ripstop for durability. The lining is 10-denier Cordura, and the high-visibility orange color serves as a marker in emergencies. Both sides are water-repellent because it may be worn over a wet shell. It's a TETON BROS. staple that staff and guides always carry in their backpacks.
