nice and warm
Love it. It's nice and warm. I was trying to decide to go with the Larger or the X-Large. I went with the XL and am glad I did. they run a little small.

4/5 stars. Easily 5 stars for quality, but the fit is on the Smaller side, albeit is life layering, sizing up would make for a great hoodie for all weather, making it a more versatile piece. Especially for the price.

I should have known better as most Simms gear is on the smaller side for the more specialized layering.

Overall they definitely were close to hitting the mark perfectly. It’s face mask is A+ and it’s not too tight either. I am 5’10” 190lbs square shoulders, athletic build. The Large fits perfect if I don’t wear a t-shirt underneath. Without one it makes for a perfect fit, a size up would have been perfect for a Tee underneath.
