Here is a list of the essentials of what you need to pack:
+ Headlamp. You will use it all the time
+ Tampons. They are expensive here.
+ Make-up. You will use it. They dress up here, it´s not like you permanently live in the jungle. And it´s more expensive over here.
+ Chacos. Bring a pair or two. I live in them.
+ Longchamp purse. It´s made out of a canvas/nlyon/waterproof material. It´s functional, easily cleaned, and fashionable.
+ A sleepsack. Mine´s silk and packs up really small.
+ Sleeping pad. (Unless you go to a ye-ye sight, you will use it alot).
+ Victoria´s Secret Underwear. The underwear is really cheap here.
+ A pair of sheets. (Do you really want to sleep on polyester sheets??)
+ Crappy lap-top.
+ I brought a bunch of cds and dvds (I still use them to update my ipod.)
+ A pair of flip-flops, and a pair of wedges. (Don´t bring hiking boots, you don´t use them. I brought a pair of running shoes and they are just molding under my bed.)
+ A pillow. (I love my pillow)
+ Airplane blanket. It does get cold here sometimes.
+ A water-proof, crush-proof camera. Go with Olympus.
+ A thumb drive.
+ Swimsuit. A must.
+ Swim goggles. ...but only if you swim alot.
+ Backpack. I have a Dueter. And I love it.
+ Jewlery. Bring the cheap stuff. Leave the good stuff at home.
+ A couple of pairs of cute clothes, and then just clothes you don´t care about. You will wear your crappy clothes in site, but in the city, you should dress up.
+ I bought a mountain hardware skirt. I practically live out of it. Buy one.
+ Tank tops from Wal-mart. Like 5. You´ll be good.
+ 2 Polos.
+ 5 Skirts.
+ 2 Jeans. (One for when you are skinny and one for when you get fat)
+ 3 pairs of Shorts.
+ One dress. (You will wear it to swear in and that´s it)
+ 3 Long sleeve shirts. I live on the beach and it does get cold.
+ 1 Northface jacket.
+ 1 Umbrella. (Rain jackets are ugly and bulky).
+ 5 T-shirts.
+ 2 pairs of running shorts.
That´s it. Don´t pack a ton of clothes. You will regret it. Mainly cause you will have to haul it all around. In Panama you can buy alot of stuff, so don´t worry. Unless you are a larger person, most clothes will fit you. If you have questions, holla.
