REI delivers a great little jacket with the Packable Fleet. It’s spare but also extremely light weight. Throw it in your pack and you have an extra layer when you need it. It should be versatile enough for morning runs and other aerobic activities.
Mountain Hardwear scores big with the Lamina. At $180, the Lamina is right in the middle of the pack price-wise. But it more than keeps pace with more expensive products.
