I usually take a medium but read a review that the sizes run small. I ordered a large but it was too tight. I am usually happy with any Kuhl clothing item but this disappointed me.

As other reviewers stated the sizing is off. I wear a large in most everything. I couldn't wear this over a t-shirt. Also the front pockets might as well be sewn shut. You can't get your hands in them. Now I have to eat the return shipping to Backcountry.

I've only used it once but i loved it and it kept me so warm with a flannel shirt on. it does run small

This is the perfect marriage between form and function! This sturdy vest feels like it'll last for ever. The fit is great. I don't think it runs small... I've found it to be true to size. The only derrogatory comment I could make is that the pockets are a bit shallow, but I suppose that's just a matter of opinion. The zippers all work beautifully and the vest wears totally naturally! Kuhl products never disappoint!

This is a really great looking vest! Looks good and feels good. Like the others have mentioned the sizing is a bit small. Runs a little narrow in the chest, so i would recommend sizing up! Super comfy otherwise, great for the cooler days when a jacket is overkill, but a long sleeve won't cut it!

I am usually M and this vest Felt a bit narrow...you might want to consider an L

This is a good vest for those cooler days when a full jacket might be a bit much. It's lined with microfleece for insulation and the outer fabric is built to take a beating. Sizing is a little weird...I normally wear a large in most Kuhl stuff but had to go with the XL this time as the smaller size felt like I was wearing a corset, so might not be a bad idea to size up with this piece.
