Fit issue around arms and shoulders

 Rated 3.0 stars

From Dan


Ordered a large. The chest and waist fit were great but arms and shoulders were tight. Lucky we have a 5.11 store local and I was able to trade for an XL. Unfortunately, shoulders and arms were just as tight but the chest and waist is now way too big. Will be trading it for another style. For $80 it needs to fit damn near perfect. Shame, nice shirt.

awesome shirt

Fit of this shirt

 Rated 5.0 stars

From Allan


I love the fit of this shirt, I am a husky built, I bought an XL it fits very nicely, I read two other reviews that complained about a bad fit, I did not find that to be the case in this shirt. I would recommend this shirt for a active life style.

Great Flannel but horrible fit

 Rated 4.0 stars

From Jonathan L


If you're at all husky dont buy this as this fits slim. I can usually get away with 2X shirts/jackets this I can barely fit and felt uncomfortable in the arms. Forget buttoning this and sitting down or doing anything but holding you gut in while standing.

Otherwise excellent flannel and craftsmanship, I really love this shirt but I have to return it.

This is a nice shirt, but needs work.

 Rated 4.0 stars

From Jesse


I'm constantly looking for functional, and action ready clothing. I bought this shirt because of the look, and when I finally got it it had a nice feel. Unfortunately the materiel of the shirt is not that flexible, I am a big guy so I got the XXL but even with that size the arms can get snug when I lift them over my head, and when I try and aim with my firearm. I think 5.11 should try and make this shirt more flexible, then it would be perfect.
