Love the shirt but wish I could buy them one at a time, not in multi-packs.

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.

They don’t last very long. They get really thin and stretch super long. Which was disappointing. After a year they were no good. So I didn’t buy them again. Considering the initial price I expected more- a six pack at Costco is the cost of 1 tee shirt but lasts like 3 years. It’s not nearly as good but at least it lasts.

The undershirts are great as far as the v and arm length. They fit great, but the armpits need to be made better. After a few uses they stain, hold oder, and at the same time dont absorb enough sweat to keep pit stains from being seen on the dress shirt. I dont perspire as much as most guys either.

Dear Customer, Unfortunately, the underarm stains are from the use of anti-perspirant and certain deodorants. The chemicals inside them cause the yellow color, not the shirts. Thank you

Great shirts, great fit, loved them when I thought they were made in the USA. The new pack I received says made in Mexico. Like the shirts, but made in the USA is important to me and therefore I will find another supplier. I see your reply, have you considered offering a made in the USA shirt option? At an additional cost?
Response from UnderFitMar 23, 2018
Dear Customer, We're still made 50% in the US, but since 50% is done in Mexico, we have to put that on the shirts. We had to switch to Mexico to find a reasonably priced factory that could deliver quality sewing. The US factories were just too expensive to make the business work. In response to your question, we've looked into that, but based on a survey of our customers, very few would pay the extra $6 per shirt for the American made version. A comparable quality garment factory in the US is very expensive. There are a lot of economic reasons the US can't produce quality garments at a commercially viable price. Other countries' governments and industries heavily invest in this sector, the US does not. Thank you for your business

Great shirts, I wear them everyday. Sometimes I just wear the shirt to go out
