Fashion, meet function.

This ultralight, windproof Brooks LSD Pullover top is sleek and stylish—and neatly folds up into itself in a tiny carry case. Brooks certainly put a lot of thought into how to create a run top that could protect you from the worst of the weather while also remaining lightweight and easy to pack up when you no longer need to wear it. It’s the perfect item to take out on a run when you’re not entirely sure what the weather’s doing, but it won’t impede you if you need to take it off and keep running. The vent in the back of the Brooks LSD Pullover helps disperse excess heat when you’re working hard and the reflective details help provide visibility for lower light runs.
