Black Diamond Dawn Patrol vs Columbia Whirlibird IV Interchange

I tried on a L that a friend had and it did fit well. So my tip would be to size down one full size. The cut is definitely not a an athletic type cup, very roomy.

I love this jacket! It fits great and is comfortable. I really like the inside synthetic jacket as well! Great ski jacket option and converts if it's warmer outside. I recommend it!

Hood is adjustable to not block field of vision. Finally it looks good and fits right to wear with street clothes in business casual (at least until it gets dilapidated from the heavy adventure use mine sees.) Somehow its got a trim fit that also allows layering good enough for lower 48 summits.

Finally, if aesthetics are important to you and you want to look good outdoors, you need to think about the style of the jacket too. Just because you want a jacket to look nice doesn’t necessarily mean that you have to sacrifice any performance.

We have gussets for arms and underarm pit zips for extra breathability. Dawn Patrol Hybrid main, jacket and pants.

I bought this jacket a few months ago and was able to take and wear it skiing a few times before the weather warmed up. The jacket not only kept me toasty, but it had all the features I needed to keep me on the slopes all day! The under arm air vents were a huge help to keep me from overheating. It was roomy enough to not pull in certain places and feel too snug when I fell on my face. I would recommend this jacket to anybody that needs a convertible jacket for the slopes or elsewhere
