From trekking across Thailand to traversing the toughest stretches of Baja, we’ve spent over 20 years perfecting the art of adventure—and underwear. And for every epic adventure, you need an even more epic undershirt (or two). That’s where the Men's Give-N-Go® 2.0 Crew Neck Tee comes in. Now up to 4 times more breathable, 50% more moisture-wicking, and 25% more quick-drying compared to our original Give-N-Go® collections, our latest iteration is designed to keep you moving more comfortably than ever. Explore more with durable fabric for long-lasting use, 4-way stretch for total range of motion, and chafe-reducing flatlock seams. The improved anti-odor treatment stays fresher, longer. Wear it to sleep, or when it’s time to get going, layer on a button-down shirt, hoody, or jacket.
