I recently purchased a different XPOSUREZONE jacket and liked it quite well.  So when this XPOSUREZONE shirt-jacket was a lightning deal, I purchased one in the same size, thinking it would also fit me well.  Unfortunately, it does not.

Just like with this one, many recommended sizing up with the other XPOSUREZONE jacket, but I'm slim, so I ordered my normal size.  The fit was great and could have even been smaller.  This one, however, is so small that I feel like I'm going to burst the stitches.  If you're a big guy, I'd even recommend sizing up twice.  Keep in mind that this is coming from someone who's slim and likes slim fits.

The jacket is very thin and lightweight.  Unlike the other jacket, I found a lot of dangling stitches.  This is something I normally wouldn't have mentioned, but there were enough that it seemed excessive.

Overall, I'd say it's okay.  If I didn't have to send it back, I'd probably like it and wear it often.  Just remember that it's a size too small and some would probably even say two sizes.
