I purchased one each of the slim fit and the regular fit to see which I liked better.

At 5'8" and 155 lbs, I found I greatly preferred the regular fit. Both shirts were of very good quality with reasonably good wash and wear characteristics, and I will keep them.

However, the slim felt too snug in odd places, like the outside of the arms, which is not where I would have expected an issue (not like I have massive guns, just regular arms). I will get more Eagle regular fits, for sure.

Both the material and the stitching seem superior to the commonly available Arrow and VH selections in stores.
