Whatever sport or exercise you love to do outdoors, now that the air is warming up, you need a thinner jacket that allows you to move.
Softshells are the perfect weight for spring. You want to get one that's wind and water-resistant like this zip-up from Marmot. It's flattering to women's figures, and made of durable, flexible material, so it'll move with you. Plus, it's lightweight (only weighs about 1 lb), so you can easily stuff it in a backpack if you need to.
Like most softshells, this one is made of breathable material. This one also has something called Angel-Wing Movement that allows full range of motion in your arms so the jacket doesn't ride up. Another great thing - the pockets have soft fabric inside to keep your hands warm.
You can order this online from backcountry.com for $249.95.
