Fill the adventurer's soft, cozy wool hiking sock ($19.95) -- er, stocking -- with eco-friendly supplies, like Burt's Bees' chemical-free sunscreen and travel kits ($13-$30). Send your favorite beach bum a supply of fish-friendly surfboard wax ($4), or these waterproof cases ($34.99) for passports, cameras and phones.
For the nostalgic surfer, you can buy great collections of movies from the '60s and '70s as well as the original "Surfing Guide to Southern California" ($12) from San Francisco's Mollusk Surf Shop. I like its funky, water-worshipping T-shirt designs ($20-$30), too!
