Going green is not a new phenomenon in the world of outdoors gear. But today's eco-friendly gear is a far cry from the hemp hoodies and low-tech "earth gear" of yore. Take these four products as examples. . .
Sierra Design Cyclone Eco
This mid-weight shell -- which can be used as a rain jacket or a cool-weather top -- is touted to be the most sustainable jacket on the market. It is made of a recycled PET face fabric with PVC-free seam tape and a solvent-free waterproof-breathable laminate. $149.95, www.sierradesigns.com (Available starting this summer.)
REI Organic Cotton Cadet Cap
Touting an eco ethos with a Cuban flair, the Cadet Cap is an organic cotton alternative to the workaday baseball bill. Bonus: The cap comes with a worn look and feel that requires no break-in time. $16, .rei.com
Aquapac Hard Lens Camera Case
This plastic waterproof camera case is now 100 percent PVC-free, meaning the case employs no polyvinyl chloride, a chemical cited in some studies as a pollutant and a carcinogen. Made for tiny digital cameras, the case has a polycarbonate hard lens for clear images and a watertight seal to keep moisture out. $45, www.aquapac.net
Teko Ingeo Light Hiking socks
Made of a biodegradable corn-based fiber, these socks have extra reinforcement in the heels and toes for durability. The fabric transfers moisture and sweat to keep feet dry and prevent blisters. $13.95, www.tekosocks.com
