Great shirts, though as someone said they’re not much better than store prices if you only get one pack.
I don’t know that they run “small”, but they’re definitely a more athletic fit. They are cut well and overall put together well. I wear a large across the board, and these in L run more snug than I would normally wear as a tshirt alone. If you want a more casual look I would go with a size larger than normal, but that’s not really what these were designed for.
I don’t mind the fact that they’re a cotton/poly blend. It makes them feel different on your skin, yes, but 100% cotton breathes about as well as a worked up Pug. The added poly combined with the fact that they’re fairly thin Tees makes them great for summer wear or to use as an undershirt.
Puma isn’t listed on this particular site, but if you’re looking for a dedicated opinion on undershirts, this is a good place to start. http://www.undershirtguy.com
I got some of these last time they were around. As stated, they are definitely “athletic” fit and run towards the small side. They are light weight, bordering on being thin. Definitely an undershirt undershirt, not a “White-T”. Also, the tagless “tag” can be irritating to the skin until it comes off (after a handful of washes). It’s a vinyl print that sticks to your skin, especially since the shirts are on the small side.
I won’t be buying more, but (now that the collar “tags” are gone on my shirts from going through the washer/dryer) I do not regret my purchase.
