I've been using a kitewing with skis and skates for the last couple winters. Getting a lot more into it (and hopefully kiting too) and looking to get a harness. Pretty much settled on the mystic blazer. But I can't decide on the size. I wear size 33 waist pants, but they tend to be worn on the hips a bit below the real waist. I also usually wear a thin ibex wool shirt, a thin primaloft one puff, and a shell over that. I get hot, but am still warm when I stop. I tried on an extra large (36-38 waist. Basically all the straps are cranked all the way down, and it while it seems to fit, at the top of the back of the harness there is a gap where it isn't tight to my back, you can stick your hand in there pretty easy. Seems like it wouldn't be supportive, but maybe if you're leaning back into the harness when clipped in it wouldn't be an issue. Almost seems like it would be like this with a smaller size, because just the waist belt won't fix it, like you'd need a 2nd set of angled webbing to pull it tight there. The place I'm buying this from is out of the large size (34-36) so I kind of have to choose between medium (32-34). Don't really know how these are supposed to fit, if they size it expecting you to have some winter layers on, etc. The XL is def too big, just not sure if the med would be ideal. Judging by the 6 or more inches of extra strap hanging off every closure, I'm guessing it would be ok. Mail order is a bitch. Any direction or thoughts on getting the size right would be most welcome.
