1. Streamlight Nano Light: Around $6, itty-bitty yet sturdy and bright. Read the full review here. Buy it here
3. CR 123A Batteries: Chances are you've got a Surefire or similar light that runs off these, and if you're anything like me, there's a good chance you'll go through more than a couple batteries this next year. Good luck finding 'em at a decent price locally; Amazon has Streamlight brand batteries for $1.69 each
4. AMK Heatsheet: Much better than those cheap-o silver space blankets, $6.51 here
5. Aquamira Survival Straw: Tiny water filter; keep yourself parasite free! About $9 here
6. GSI Stainless Steel Nalgene Cup: Nests perfectly on the bottom of a standard Nalgene bottle, great for boiling up a cup of water. $8.95 right here
9. Elago Micro SD Reader: A tiny micro SD reader, just a smidge bigger than the USBl connector. Sized for wallet or urban pocket survival kit carry, or even just small enough to keep it plugged in most of the time. Keep a Micro SD card in it and it'll work like a standard USB memory stick. Or if you need more storage space, you can keep additional Micro SD cards nearby. $9.00 right here
10. Shemagh: A favorite in the Mid East and adopted now by special forces and tier 1 cool guys, the Shemagh is a multi-functional piece of gear. Use it for everything you'd use a bandanna for, plus the added length gives you additional options--face covering and so on. It's pretty damn cold in most of the country, and this will keep your face warm, too. $7-$11 from Amazon
