Recently I impulse'd on a Senchi Designs 90 zip hoody. A lot of my hiking friends have sported the material this year so I snagged one to check out. I do not have any in field testing on this product yet, I will this fall, but first impressions are great craftsmanship, quick shipping, and extraordinarily light.
I mean...Its basically see thru so this is most definitely not a stand along, protect you from the elements garment. This seems more like a cozy, wear under your puffy to really boost your insulation properties for very little weight penalty. I could see wearing it on cool fall mornings, in the tent at night before bed....but not as the only garment I would bring to keep me warm warm.
They also make this garment in a lighter and a heavier version. I don't know what purpose I would have for anything lighter in material weight but could see the 120 being suited for more stand alone situations.
Anyone else check this stuff out?
