Clearly, your shirts are the best fitting t-shirts I have ever purchased (and the material feels great too) - finally, I can wear a shirt that fits my shoulders and my torso correctly rather than the typical t-shirt which to me is like maternity-wear.

- Jim, San Francisco CA,

Just received my order today. Can't tell you how much I love them! Not only are they comfortable as an undershirt for work, they fit so well and look so good. I'm just going to wear it out with my favourite jeans on this sunny warm day in London. I have never had a good fitting t-shirt before Threadmason. You know how difficult it is to find anything that fits well with a small frame like mine? Keep up the good work!

Threadmason has created a wonderland of fit and comfort at levels unprecedented by any other t-shirt manufacturer out there. They have combined ingenuity with quality craftsmanship, and the results are magnificent. In comparing my old t-shirts of various brands to the Threadmason tee, I was most impressed by how comfortable the Threadmason tee was, while still complimenting my slim upper and lower body, as well as my arms. This shirt feels more like an investment than a purchase. Well done, gentlemen.

- Scott, Bellevue WA,

I decided to order your T-shirts as I've never been able to find T-shirts that fit me properly. Sure, I can find T-shirts that fit me around the shoulders and waist but invariably, they are either really snug and/or end up being too long in length. I bought the S1A and they are really different from my other T-shirts. They are loose but still well-fitted. They also feel very comfortable to wear and seem to be durable. Overall, I'm very impressed and that's not even including the fast delivery to Australia. I will definitely be buying more and will certainly recommended the brand to my friends.
