When Jackson, Wyomingbased Cloudveil promises a do-it-all mountain soft shell for under $150, the smart money gives it a try.

The key is a stretchy polyester fabric that's water- and wind-resistant but air-permeable, meaning it allows a little external air conditioning to prevent overheating during highly aerobic activities. 17 oz (M); cloudveil.comBonus: It dries faster than soft shells made with Lycra.Bummer: It's not as windproof as some other air-permeable jackets.
