I thought it weighs 2.5 oz???
While visiting Denver over the weekend, I made a pilgrimage to Mecca (the MB store at Boulder, CO), to worship at this gear shrine but also to pick up a trowel (handy scoop). All the excitement of seeing and touching their various garments, tents, packs, etc. -- I completely forgot about the trowel, and now, I'm back in LA! :(
Anyway, I really like the UL wind shirt -- definitely lightweight and feels good next to skin. As for color, the sax color is nice, but the transluscent/flourescent green is seriously ugly.
