my favorite walk around shirt
I get a new one every few years to add to the collection. Athletic fit, great look, warm with a long zip to let in air when needed. I wear one all the time around town, walking the dog, to work.

Awesome Cool-Weather Top
I've worn my Transition Zip top, no base layer, on several cool-weather (45-60 degrees F) hikes with extremely impressive results. Despite a good pace, it really wicked the moisture away well; at the same time, though, it easily stops wind gusts. The best of both worlds. Bear in mind that rubbing will degrade the finish, but with such performance, it's worth being extra careful! I highly recommend it.

Great product!
This top is excellent for outdoor activity. The ability to block the wind has many benifits. It keeps the upper body warmer without bulk.
