My Story:

As I’ve gotten more into mountaineering, I have discovered that I need very different gear than I had for traditional summer day-hikes. Pursuing hikes and scrambles in the winter, I have had to rethink layering and protective gear at a much deeper level. When my aunt told me she was clearing out some gear and asked if I wanted any, I was skeptical, but when I saw the Mountain Hardwear Ozonic Jacket in such great condition, I jumped on it!

This jacket does not disappoint! I’ve used it as an outer layer on a soggy northwest conditioning hike, and as a protective layer for ice axe arrest practice in bright sunlight. I put the “abrasion-resistant” claim to the test as I hurled myself down the slope over and over demonstrating different ice axe arrest techniques, and this jacket held true to its reputation! The zippable sleeve vents are a lifesaver then it gets warm, and the water and windproof fabric kept me comfortable at a standstill on Mailbox Peak and Mt. Si when conditions were less than ideal.

What could be done better:

Granted that I probably use this jacket a little differently than it is intended, but I would like the inner snowskirt to be a little beefier or have a different connection to the jacket. During some of my downhill plunges, I had to stop and pull out snow several times that was caught between the jacket and skirt. Also, it is a very comfortable and flattering fit, but I don’t think I would have been able to squeeze another layer into the sleeves had I needed it (there was some stretch/give in the core but I had to take my time working the zipper up when I had layered up, and that was without my thicker puffy on). Otherwise, it’s a great jacket for my mountaineering purposes!
