My DS is completing Session 1 today.
I beleive this is what you are looking for:
ITEMS TO BRING WITH YOU
You will be issued six Summer Seminar t-shirts, a pair of sweat pants, and a sweat shirt. You only need to bring 1 – 2 sets of civilian clothes for travel and academic workshops. Dress is informal but neat in appearance. Shorts or pants must be tasteful, please do not wear shorts or pants that are tattered, torn, or have holes. Closed toe shoes are required for daily events (i.e. sandals are not acceptable). (The temperatures may be in the 80's, 90's, or 100’s with possible showers, and high humidity. Due to the exceptionally high temperatures in Annapolis in June, shorts are encouraged). Remember, you will have physical training at 5:30am every day without the ability to do laundry.
Be sure to bring:
1. Appropriate athletic shorts (4 pairs)
2. Socks (10 - 12 pairs)
3. Undergarments (10-12 pairs)
4. Towels (2-3)
5. Twin size bed linens (1 set)
6. Pillow and pillowcase
7. Toiletries and shower flip flops
8. Running shoes (You might want to bring a second pair of older running shoes for the Team Building Exercises).
9. Swim Suit. For females, a one piece swim suit is required.
10. Travel alarm clock
11. Photo ID
12. Bring a combination or key lock for clothing lockers.*
*Do not bring excessive amounts of money or other valuables as safekeeping facilities cannot be provided and the Academy will not be held responsible for lost or stolen articles.
BTW, don't forget to wear a belt as you will be instructed to tuck your shirt-tail at check-in. You may also want to get a haircut as you are going to get real dirty at the session. Check out the pics at:
