UHB stands for Under Helmet Balaclava. The top part of this balaclava is made of a "moisture wicking polyester", the bottom is fleece. This is distinct from the BEB balaclava (best ever balaclava ) which is all fleece. I was annoyed that there was no descrip, so I added it.

Sigg screwed up. Their old lining material had BPA, a sort of artificial estrogen that is used in plastics. The new lining (the white lining you can see in the pictures above) doesn't have this, so no worries.

The wide mouth is the best innovation that could happen to Sigg bottles. Doesnt add much weight, and extra functionality. Finally, ice in my sigg bottle! The small cap is 100% compatible with all other small-cap tops that Sigg makes (e.g. the sports caps). The ridges make the bottle stronger and more dent resistant.

This is a very warm jacket that has been marketed to be professional grade, but designed for regular people doing regular things in very cold weather. It is not professional grade, but if you are a regular person, this is more than enough unless you plan on doing something actually life threatening. Remember, a jacket is only one part of the gear that you need for extreme cold, and if you are not fully equipped, dont blame the jacket.

Plusses: Strong durable high denier shell material seems to do well against abrasion, and is extremely waterproof. In the rain, however, the synthetic ruff looks like a wet cat. Plenty of pockets are a plus, and the shoulders are quite flexible and do not impede motion. Dual draw strings ensures that drafts from the bottom are mitigated.

Minuses: Down Baffling is inadequate, keeping this from being a truly great jacket. Insufficient baffling, notably around the shoulders and armpits, causes down to shift, producing cold spots. It's still warm, but the same amount of down could go so much further with intelligent baffling. No internal cuffs, no core venting, low quality zipper pulls, hood too deep, headphone cable management is inadequate, primary zipper is insufficiently durable. Chin guard on the top of the zipper is not plush enough, storm flap on the zipper is not warm enough, using snaps instead of velcro on the storm flap was a bad idea for thermal reasons. Replacement fur ruffs should be sold online, with options of real coyote instead of synthetic. Draw string cuffs and glove clips would have been nice, as well as D-rings for attachments.
