I whare medium sized tops and did so in the army. This fleece jacket fits a bit sug in medium. Recommend if you know your medium get a large size or one size bigger then you are. Jacket is vary warm and comfortable also came with two of green subdued American flag patchesPerfect fit, especially while on duty. This jacket fits really well over your vest. The hook and loop is awesome as well , I've put two department patches on both sides of the jacket. The length of the jacket is perfect, it doesn't cover any of your gear on my rig. Shipping was fast.Not tan more of the Coyote Green look to it. I still like it. I am 5'7'' and 145 pounds the Small fits well.Just like the previous two Alpha jackets, fits well, color is great, have gotten a few comments on the jacket, and the price was excellent.Right on time with a local artic blast. Great for layering.Very good product, good construction.I purchased an size XL, it fits well, I'm 6ft tall and weigh 200 pds.Great sweater, bafric feels good, and the size fits perfect.Awesome jacket ...highly recommended
