T-shirts and water have always gone together great, whether it was at that awesome dive on spring break, or during any other dive when you didn't want people to see your jiggling man-boobs. For tees supporting a liquid cause that isn't preventing ridicule, check out One Hundred.

Just launched by a UVA grad disillusioned with the frat-antics of some of his colleagues (clearly dude did not get invited to Zete late-night), 100 designs smooth graphic tees, each of which's purchase sends $5 to charity: water and their efforts to build wells, prevent disease, and promote sanitation. Spread health & style with:

1. CMYK Droplets: This primary-colored joint's made from premium cotton that's 100% "ringspun", so it must've got caught coming off the ropes against Stone Cold or something.

2, Logo Aqua Shirt: With a name presumably conceived after months of creative brainstorming and crumpled-up failed ideas, this bubbly number's the only one available solely until the end of summer.

3. Raindrops: Because "every drop is precious", this super-soft cotton/poly blend depicts an umbrella flipped upside down to catch them, and is available only in the color "black ocean" -- perfect for fellow precious drop-believers BP.

And because the planet apparently has a lot of gross water, they'll also soon be dropping a line of similarly designed hoodies, ensuring that even when it's too cold for a t-shirt, you can still make a splash.
