Here's what others have to say...

This jacket seems to be the replacement...

This jacket seems to be the replacement for the beloved Catalyst jacket. Is that true? I lost my original catalyst jacket and have never been the same since.

Marmot still makes a DriClime Catalyst Jacket

How is the fit compared to the Marmot...

How is the fit compared to the Marmot Catalyst jacket?

The Atomic is an athletic fit, so it fits a bit closer to the body than the Catalyst. It has stretch, so it works great for active users.


Sweet Running Jacket

    This jacket rocks for chilly morning or misty evening runs. The windbreaker outer fabric keeps the drizzle from soaking your under layers and the super soft inner fabric is cozy and absorbs sweat when you heat up. There's an inner pocket for extra gear, and a chest MP3 pocket that is great for keeping your tunes on you. Fits true to size, i'm 6'1", 185 and a large is perfect.
