Best undershirts I've ever had
Best undershirts I've ever had. I even wear them with casual clothing. These shirts have become an essential layer of every outfit.

UnderFit undershirts are cut longer and lightly hug your hips and below, to stay tucked in all day. Our fabric is ideal for undershirts due to its exceptional softness, advanced moisture absorption, odor resistance and superb breathability. If you want to remain less comfortable in your run-of-the-mill undershirt, by all means, DON’T buy an UnderFit.

Searched a wide range of brands to find the right undershirt, then I found underfit. I have a drawer full of crew and v neck and wear them all year round. Super comfortable whether it's freezing NYC weather or sweltering summer. Won't buy, or wear, anything else.

I've been wearing underfit shirts for a long time now - a perfect combination of softness, deep V neck to avoid the shirt showing even under dress shirts, and a great feel

Under fit shirts are the best shirts ever. Especially if you have to wear button down shirts tucked in. Worth every penny.

The UnderFit shirts feel great against my skin and look perfect!

Best undershirts I've ever tried (and I've tried a bunch). So comfortable I forget they're there. And they never come untucked. And the sleeves are short enough they don't peak out of my t-shirts. 6 ft, 175 pounds and medium is perfect for me.

Ease of ordering
Jean-Pierre F.
I placed an order from Canada with Underfit and had issues receiving it within a suitable time frame. I expressed my dissatisfaction with respect to these circumstances and the Underfit company quickly contacted me to rectify the situation. I would like to recognize the quality of their customer service which is quite rare these days. They've regained my trust and respect and I wouldn't hesitate to reorder from them again. Thank-you Underfit!!!
