1. GoLite Bitterroot Down Parka: 13 oz. Packs small, lightweight, and keeps me toasty on long evening walks on the neighborhood trails in single digits. Love the hood, can fit easily over a helmet if climbing is your thing but not too loose to be annoying. And for $150 right now I honestly don't think you can beat its value compared to any other down jacket of similar quality, which is outstanding.
2. Mountain Laurel Designs SoloMid: 14 oz. Okay, okay. So technically I do not yet have this particular piece of gear. Should arrive in a few weeks. But it has been my most anticipated purchase in, basically, forever. I'm counting it as a 2012 purchase because I did in fact place the order on New Years Eve, so it totally counts. I've NEVER been so excited to set up and seam seal anything, ever.
3. BPL Membership. 0 oz. Best value-to-weight ratio of anything I have ever purchased, hands down. As a relatively new convert to the world of UL backpacking, I discovered BPL in April 2012 and instantly bought a membership. My eyes have been opened to a lightweight world hiding right under my nose for years. In my defense, it might be because I have a big nose (I'm currently considering getting a nose job, see if I can shave a few grams off my base weight). I'm truly thankful for the articles written by the staff, but even more thankful for reader contributions. You guys are the reason this site keeps on chugging. What inspired me the most to take the UL leap was how passionate this community is about both lightweight backpacking as well as lightweight living. So keep it up, everyone!
