Get a 3-Pack of these tank tops, and you'll likely get by year-round without much laundry hassle – the armpits get aired out anyway, and merino wool is a relatively low-maintenance material.
If you insist on getting just one tank top, here they are.
The traditional cotton tank top is popular for a reason. However, it could be better if it was made of, say, merino wool. Like this our own production shirt here. Pretty much unisex shirt, thanks to the very nice fit!
Merino wool stays comfortable even when wet and doesn't easily absorb nasty smells. You can usually just air it out without even washing it, thanks to the natural antibacterial properties of this wonder fabric. Merino wool is even better due to its finer weave. Thin enough for summer use!
