I have three pieces of the DriClime. Two are the original and one is the windshirt. My goal was to use it as a layering piece under a pro shell. I found the windhsirt to be too light and didn't provide sufficient warmth. Although I did keep it as it will make a nice casual windbreaker for later this spring. I am not familiar with the Catalyst but have become a huge Marmot fan over the last several years. Good Luck with the decision.
