Great Wind Block
I've used this in the winter XC Skiing, in the Spring at ball games, it is a great light weight wind blocker and enough insulation for active wear, highly recommended.

Good Buy
Comfy under or over layer. Breaths great, looks great. I use it for running on cold mornings or hiking. I found that the fit is a little tighter than other Mountain Hardwear gear.

anchor piece of my outdoor activities
I recently cycled cross-country and spent 8 weeks camping and riding. I wore this shirt virtually every day at least until the morning chill lifted. The form fitting makes it ideal for cycling and other active sports. It was either stolen or it fell off my trailer on the last day of the ride. One of the first things I did upon my return was to order another for my upcoming cycle of the Alaska Highway.

Best All-purpose layer you can buy
This is the 5th version of the Transition Zip T I've owned over the last 6 or more years. They're all still in constant use, and have worn very well. They're my main layer for everyday alpine skiing, and the only layer I wear while skinning. Perfect garment. The early ones were a little heavy, but this newest version is just right.

Great Jacket
All of the Mountain Hardware Transition line of clothes are great. Light to carry, good for light rain, breathes well and works well for layering. Just keep in mind that it is form fitting.
