Got this sweater jacket to layer under an OR Celestial shell. Great ultralight combination for most any conditions down into the teens. I'll be using the combo for hiking/climbing and the jacket is replacing a down vest that's gotten many years of use.
The jacket itself is amazingly light and well finished - the cuffs, zipper, pockets all feel right. The only drawback is the gussets at the armpits. They're just too tight. Even with only a light shirt underneath the jacket cuts into my armpits. I'm a medium with the only common problem of sleeves being too short. On this jacket, the sleeve length is good and every other measure is fine except for being pinched in the pits. An extra half inch or so through the gusset would be all this jacket needs to make it a complete winner for me.

Pretty good as a glacier climbing glove into mid winter conditions. The original liner glove did not seem to fit me or the shell too well. Consistently bunched up on my little fingers and would have a battle to get my fingers straightened out when I put the gloves on. Replaced with a pair of Mountain Hardwear Power Stretch gloves and this made a huge improvement. Now the gloves are good down to around 0 degrees F, provide good dexterity for a glove of this type, and remain dry working wet rope through the day. I'm pretty happy with them but a better liner to start with and a looser gauntlet would be good.

This jacket is an absolute must. Every piece of Mountain Hardwear gear I have has been well made and this jacket definately is. Just putting the jacket on feels good - you would swear it generates heat. I've worn it to about -20 degrees F and was toasty warm. It even makes a great pillow when night comes around.
