Ok, my wife sees the XL on the bed and thinks it’s a medium for her. She tries it on and it’s a bit tight, but it fits. Now it’s hers. Maybe as a base layer, maybe over something, maybe something to sleep in (she likes the Ninja hood to help with drafts under our two-person quilt). We’ll be in the Canadian Rockies for three weeks in Aug and she’ll find out.
So I ordered an XXL. Looks sort of like a men’s L, still somewhat tight, but not overly so. Hood fits better, too. Suitable as base layer and should work ok over another base layer, maybe over fishnet if it’s cold. Will figure it out in Aug. Recall it’s 100% Lycra, which I have no experience with.
N.B. they don’t advertise XXXL, which likely would fit me even better.
Finally, if you see Ninjas hiking in the Canadian Rockies in Aug, you’ll know it’s us!
