Windshirt sizing advice

I find the Patagonia Houdini baggy as well. When I use it for running the mid section is to voluminous. I had a medium but it was to tight on my chest.

The Montane windshirt I have has a nice cut to it. Loose enough in the shoulders for light layering but trim enough in the waist not to get in the way.

Adrian, I have a Wisp size M and find it tailored just right: not baggy yet with enough room to accommodate a fleece layer comfortably if needed. The only thing don't like is the lack of a hood, otherwise, it's great!

The trouble with ultralight windshirts is that they are made of a fabric that doesn't stretch. So when you get one that "fits" like a normal shirt would, it's too constrictive to a full range of movement. I'd suggest either a) just tuck the baggy shirt into your pants to eliminate the parachute effect, or b) get a softshell windshirt made of a relatively windproof fabric that has some stretch to it. The trouble with these types of winshirts is that either 1) the shirt is made of both a UL windproof fabric (non-stretchy) but with small, non-windproof stretch panels, or 2) the fabric is simply heavy or too hot (e.g. Windpro fleece). This is why I just tuck in my windshirt, or use the bottom drawcord to stop drafts.

Hey Adrian,
the Rab Quantum is great. I have the Houdini as well and I would consider the Rab to be very athletic in comparison. I had the same issue, running in the Houdini drove me nuts, and after a while found the hood to be uselss. Check out my pic in the review for fit. I am 6'4'' and that is a large size. Snug fit, but very comfy.

Yeah the Rab Quantum windtop looks good… sadly according to Prolite, Rab have discontinued it.

Montbell Stretch Wind looks to be the lightest snug fitting but comfortable (due to stretch) windshirt around:
