Just received this jacket in Lapis and I'm so stoked on the features that I'm gonna review it before I use it to set some specs straight. 1st off this jacket IS insulated, the specs are wrong. Secondly the hood is NOT removable. Third the powder skirt IS removable. Alright thats it for the specs, now onto some just plain awesome features that I can't wait to use. There is a removable balaclava stashed in an inside pocket just below the hood. It is attached to the neck of the jacket by two buttons. It will be awesome on super deep days when I'll need a snorkel. The other awesome feature I would like to talk about here is the media pocket. Great little pocket right next to the zipper with an insulated Ipod sleeve, also on the inside of the jacket is a rubber device to keep your headphone chord in just the right spot while you rip. Lastly sizing, I am 5'9" 135 and I got the small which fits perfectly with the correct amount of baggy steeze. Again I just got this jacket and cannot attest to its performance, I will be updating come winter, just wanted to point out the awesome features.
