Best Undershirt for Men

It’s a little surprising how difficult it is to find a quality undershirt or go-to everyday cotton tee. I feel like I have been on a never ending search for decades. In addition to a handful of go-to workout shirts, it’s helpful to own a handful of cotton shirts which are comfortable enough to wear:

1. On their own when you go out or around the house
2. Underneath hoodies or button-down shirts
3. At night when you sleep

The problem with most cotton undershirts is they either get the collar, fit or fabric completely wrong. You ideally want an undershirt which has:

1. A tight (but not too tight) collar which stays consistent and never bacon necks
2. Breathable cotton which is easy to care for and feels light in the heat
3. Relatively inexpensive
4. No pit stains or odor buildup
5. Appropriate length in the arms and torso which doesn’t shrink too much

I spent decades of my life wearing those 3-packs of Polo Ralph Lauren undershirts you find at Marshall’s or TJ Maxx. While they were serviceable, they always inevitably failed in at least 2 of the above 5 factors (namely in the collar). Ever since I have been trying virtually every undershirt I can get my hands on.

Uniqlo’s Supima Cotton Crewneck is the best I have seen among all the alternatives. I love wearing these at night to bed and underneath hoodies. It’s collar is perfect, the cotton is very comfortable for all weather, it’s under $15 and pit stains/odor are never an issue. The only thing that is keeping this from being a perfect shirt is the sizing and post-wash fit. These definitely shrink a little bit (call it like 10-15%) in the wash which can render the length too short in the torso if you buy your normal size. Sizing up addresses the length issue but leaves it feeling a little looser than I prefer in the chest and body. I still prefer sizing down and still consider this to be my favorite undershirt on the market but make sure you test out the sizing yourself to confirm before splurging on 4-5 of these.
