Researchers at Mass General-Harvard Medical School and Boston University School of Medicine have developed a topical drug that activates skin tanning from the inside out — without the risk of UV damage. Of course, when you’re out in the sun, it’s best to wear sunblock and full-coverage shirts to minimize the risk of UV-related damage. Made from materials like sweat-wicking polyester, breathable cotton, and temperature-regulating linen, the best long-sleeve shirts for hot weather come in lots of styles, including crisp button-downs, basic crew necks, and golf polos, so you can find one for every occasion.
Material is one of the most important considerations when it comes to shopping for the best shirts for hot weather. Polyester and nylon are both known for their moisture-wicking properties, which is essential when you’re working up a sweat, but they tend to be less breathable, and may retain odor over time. Meanwhile, cotton is more breathable, but slow to dry. Linen likewise promotes airflow — in fact, it even helps draw heat away from your body. Your choice will depend on your priorities, but you can always opt for a blend that will give you a balance of qualities from multiple materials. Plus, while most fabrics offer some level of sun protection, there are certain brands that list their UPF rating (similar to an SPF rating). A UPF of 50 is considered to offer a high level of excellent protection while lower UPF levels — down to 30 — provide protection that’s still considered to be very good.
As far as style, a classic button-down shirt is great when you want to look polished (say for an outdoor wedding or work picnic), and it generally allows for greater ventilation, as it tends to hang looser on the body. On the other hand, a long-sleeve crew-neck T-shirt is a solid everyday basic that offers tons of comfort and a more casual feel. So whether you’re looking for a durable athletic tee you can wear while working in the yard, or a button-down you can sport for an al fresco dinner, these are the best long-sleeve shirts for hot weather.
