Mountain Hardwear Transition Super Power Softshell Jacket - Men's - 2009 BCS

This thing is the perfect layer for skinning up in. It breathes really well and is totally windproof! It is also slightly water resistant. The only downside is that its ugly as sin.

I own the Transition Hooded Jacket and the Super Power Hooded Jacket, so I was going for a Trifecta with this one. But the arm holes were too high and tight and I found it uncomfortable to wear. The materials, the style, and the idea are great, but the arm holes just aren't designed well. I don't have this problem with the two sibling garments. I'm not a muscle man either, at 5-10 and less than 140. It's interesting to ponder whether this is the most or least essential of the three garments. You could say that the weather is either severe (Transition Hooded Jacket) or not (Super Power Hoody), so this one isn't really necessary. On the other hand, you could say that especially in directional sports (like running, cross-country skiing, or skating) where the weather always seems to be in front of you, it's the most essential. One additional consideration is that this one lacks a hood. I love wearing the other two. This one I returned.

I bought this as a running jacket. I wore it around town today 33 windy/rainy with light base layer underneath and I was comfortable. I can't believe something so light can regulate my temperature so well.

This is the first piece that I bought from Mountain Hardwear. I am very impressed so far. Lightweight, and it breathes well. Like the previous poster said, it does a great job of helping your body regulate temperature due to the combination of windproof fabric as well as the stretchy stuff. If you want something to keep you a bit warmer though, I'd buy something that is made of entirely windproof fabric instead.

This is a primo item-- perfect as an outer layer in cool weather and a killer inner layer in the cold. Great for cycling, cold weather running, climbing, and all sorts of backcountry activities. I'm 5'11'' 155 and the medium is a trim fit with room for a couple of lighter layers. The thumb loops are perfect for keeping hands warm under gloves when skiing or ice climbing.

The combination of materials on this jacket is perfect. This is the only thing I can wear and remain cool while running hard, and keep warm when I turn into the wind. The colored portion is windstopper, while the rest is stretch tech. The jacket has a trim, unrestricted fit given most of the material is very stretchy.

I have been wearing this comfortably in temps from 0-30 degrees F, with varying winds. If you run in the winter, this is the perfect jacket. I am 5-8, 135 lbs, a small fits great, but the collar is a little tight if zipped up.

This is an excellent garmet for cold weather aerobic activity. I use it for Alpine Touring uphills and early season road biking. The only thing I would like is a chest pocket for an i-pod / phone.
