    Comments about Outdoor Research Inertia Jacket:

    I bought this jacket for downhill skiing. It's a great jacket. Good pockets for storage and I really like the two chest pockets. The fit is made for layering so without layers the sleaves fit a little long but no issue there. I'm 5'10", 160lbs and wear a medium. The thumb hooks are a really nice plus. I didn't think I'd use them at all but have found myself from time to time doing so. Construction quality is top notch which doesn't surprise me as this is an OR jacket and I've not had issues with their gear in the past. I haven't had a chance to really use the chest vents yet. I am curious if these will work better or worse than under arm vents but only time will tell.
