Suit Up for Stealth | Product Reviews | Wired.com
A friend and I first tested the on a Summit of Mount Shasta, a 14,162-foot volcano in Northern California, and then took the on a weeklong trip through Colorado’s Rocky mountains.On Mount Shasta, the Airblaster proved more than capable of handling the temperature swings that come with the higher elevation. When using it as a base layer, my tester found that he didn’t need any other layers under his shell jacket and pants to provide further insulation. The thin merino provided heat when it was cold and kept him from overheating when he started pushing uphill toward the summit.In the Rockies, the temperatures dipped below 30 degrees at night, but the I/O Bio Pilot suit did a great job of keeping me warm. The form-fitting hood and thumb-looped sleeves kept warm air in the suit.
