Frequently Asked Questions About Men’s Undershirts:

What are the best-quality men's undershirts?

Quality comes down to 2 things: the weight of the fabric and the "stay-put" factor. The best undershirts use long-staple cotton or high-performance synthetics that won't pill or thin out after a few months of heavy wear. You should also look for a longer tail and a bit of stretch, which ensures the shirt stays tucked into your waistband and maintains its shape instead of becoming a baggy mess by lunch.

What type of undershirt should men wear?

It depends on your top layer and your activity level. If you’re wearing a button-down, a v-neck is great for keeping your undershirt hidden at the collar. For manual labor or high-heat environments, a crew neck made from moisture-wicking fabric is usually the better call to provide maximum sweat protection. Ultimately, you want a fit that’s snug but not restrictive – something that feels like a second skin rather than an extra layer of bulk.

How do I prevent my undershirts from shrinking or the collar from sagging?

A sagging collar usually happens because of low-quality ribbing that loses its "snap." We use reinforced collars designed to sit flat and stay that way. To keep the fit consistent, wash your undershirts in cold water and avoid high-heat drying. High heat is the enemy of elastic fibers and cotton – keeping things cool ensures your shirts don’t shrink up or lose their shape after the first laundry day.

Can these undershirts be worn as standalone tees?

While they’re designed to be a base layer, our undershirts are beefy enough to hold their own. Unlike those paper-thin shirts you find in a plastic bag, these have enough density and weight that you won't feel exposed if you decide to shed your outer work shirt when the shop gets hot. They offer a clean, classic look that works just as well on its own.
