When I tried on the first one of these I immediately thought it might be the most comfortable undershirt I have ever worn.  As far as fit, I am a bigger guy with a 46-48"" chest, and the XL fit exactly the way I like - relaxed and comfortable with a little room.  Even when I used to be skinny I never liked clothes to be fitted and snug.  Some reviewers have complained that the v-neck is too deep.  I do not find it any deeper than many other brands I have tried like Jockey.  In fact, I had been wearing it for an hour or two before I even thought about this so I took off my top shirt and checked the mirror to be sure I had not missed something.  Besides, I never wear just an undershirt except to sleep.  Some reviewers have complained that the fabric is thin.

It is a little thinner than some undershirts, but not really noticable thinner than the 100% cotton Hanes v-necks I have been wearing.  This was actually a good feature as far as I am concerned for a couple of reasons.  I live in New Orleans where the weather is hot and very humid most of the year.  I ALWAYS wear an undershirt, even under t-shirts and polo shirts.  May be wierd, but I prefer to have something soft against my skin and to have that extra layer to absorb perspiration.  It is probably my imagination, but to me it actually feels cooler.  The other reason is for travel.  I try to travel light so for trips of a week or more I like to take maybe 4 sets of quick-drying underwear and undershirts that I can hand wash and dry for re-use.  I have some very thin microfiber briefs and shirts that do nicely, but they were very expensive, and the XL briefs and shirts fit more like mediums so I have never liked they way they feel.  I was surprised at how hard it is to find such things.  Now that I have tried these Hanes FreshIQ Comfort Blend shirts they will probably be my full time choice, not just for travel.  After a brief trial I can see myself ditching all of my current undershirts and replacing them with these!

Some reviewers have said that these shirts are not very durable, that seams have started to separate after fairly short time.  Honestly, if I can get a year of wear out of them, I think I will be happy to replace them!
