We're coming out of a harsh winter here in West Virginia and I'm bummed to not be wearing this jacket as much. This jacket kept me super warm through the long belays of winter.
The Maestro is by far the warmest down jacket I've owned with plenty of down packing the baffles. It offers a loose fit for wearing as a top layer over any number of internal layers but cinches down in drafty areas once on. There are draw cords at the waist, neck, and back of the hood, while the elastic cuffs were tight enough to prevent cold drafts at the wrist. The hood is very thick and warm.
I honestly can't think of a single improvement for this jacket.

I live in a cold place, Gunnison, CO, and I need a "go to" really warm jacket that functions well for everyday. I'm not belaying on an ice climb, but I do ride my towny to get the Sunday paper. The Sunday paper (giant) fits perfectly into one of the two "Shove it" pockets. These pockets also hold my hat and gloves when I go inside somewhere. You can put small things in big pockets but you can't put big things in small pockets. I also like the non-zippered hand warmer pockets; they're always there, warm and ready. There's plenty of other secure stowage, inside and outside zippered chest pockets, as well as a huge zippered rear pocket. The hood is always there if I need it and I can pull it over my bike helmet. Lightweight and ultra packable, I can bring this jacket anywhere and it barely takes up any room in my luggage. Best cold weather jacket I've ever owned.

I bought the Maestro Jacket to use for a intermediate weight belay jacket and for cold alpine bivies. The jacket is very light weight, this was achieved by using a lightweight Pertex shell fabric and high quality down. As a result the Maestro is very compressible, more compressible than the large rear duck pocket (which turns into a pillow) so if you really want to pack down the jacket consider picking up an extra OR stuff sack.

I ordered the jacket sight unseen so I wasn't really sure how to compare this jacket, all I had to go off of was the Virtuoso that I already owned. The Maestro is comparable to the Rab Neutrino Endurance although slightly lighter. Compared to the Virtuoso the Maestro is cut much more generously in the torso and arms and much much longer in the back. The Maestro is baffled in the body and arms instead of sewn through with the Virtuoso. The Maestro has substantial loft and no light shines through when holding it up to a light. This jacket weighs less than my 100gr Primaloft synthetic jackets that I would normally have in my pack that provide much less warmth.

The attached hood is large enough to fit over my climbing helmet...easily. However, you have to unzip the collar to raise and lower the hood. The collar is separate from the hood to keep out drafts and snow when the hood is down.

The downsides:

- No front pocket zippers
- Low neck collar

I'd like a collar that covers my face, if I have this jacket on and the hood up chances are my face needs insulation as well. Other jackets on the market address this and I think it's a good idea. Certainly not a deal breaker but would be nice. Overall a great jacket, I'm glad I bought it.
