We got two black under armor golf shirts (black with gold), a gray under armor hoody, an under armor backpack (a cheap one, the strings that you pull to close the top are also the straps), and three under armor loose gear shirts for PT, in black, white, gray, dark green, or black depending on your platoon. The year before us got camelback backpacks, but we weren't that lucky. O, and a nalgene type water bottle.
I'd suggest taking like 2 pairs of athletic shorts, 2-3 khaki shorts, a pair of khaki pants (they're required if you take the chemistry class), tons of socks/underwear/compression shorts, and jeans and a long sleeve shirt. and maybe 2 pairs of good running shoes. Also, undershirts are good for the golf shirts, which u wear to class and briefings (you go to like 2 days of briefings AKA info sessions), so that those shirts don't stink after a week.
Also, i think someone else was wondering about classes? We went to three total.
