- Go for a brisk autumn run in the Quest Lightweight Packable Jacket with courage and confidence. Thanks to a water-repelling property, you’ll stay dry when it rains, while underarm and side-body ventilation ensures you won’t overheat. Zippered pockets provide secured storage, and reflectivity touches keep you visible in low-light conditions. And if the day ends up warmer than you thought, you can pack it up and toss it in your bag.
