I didn't see this post anywhere, but I might have missed it. 

I know Tynan just posted his gear post, but I'd like to suggest a few things to those of you who want to   change around what you have or maybe you happen to be looking for something to try out. 

First of all, I use this headlamp for everything.  It uses 18650 batteries, which aren't cheap, but are rechargeable.  The lowest setting seriously will last as long as they say it does.  The brightest setting is incredible for navigating at dark if you really need that much light. I hike at night and fell into a creek with this on my head.  Thankfully I had this, because it still works without issue!

Guyot Microbites are infinitely useful for me as well.  I even cook my breakfast using the spatula.  They snap together, are cheap, and easy to clean. 

I can probably recommend more stuff, but I'm more intrigued as to what other gadgets people out there like.  Interested in anything.
