Handcrafted from pre-shrunk cotton duck. Available in Natural with Forest Green underbrim or Khaki with Olive underbrim. The Wonders of a Tilley Hat: - Guaranteed for life-Free replacement if it ever wears out, falls apart, shrinks or mildews. - Insured against loss or grievous damage-2 years, all perils, 50% deductable; we will always meet you half way. - Blocks the sun-All Tilley Hats and the Cap have the AMC Cancer Research Center's highest certification rating, an ultraviolet protection factor (UPF) of 50+. - Thar she floats-A non-absorbent foam liner in the crown adds buoyancy and noggin protection. But the Hat does not replace a personal flotation device. - Won't shrink-Machine or hand washable. Air dries in a few hours. - Rain repellent-Your glasses stay dry and you'll need an umbrella less often. - Blissful comfort-Designed to fit low and fairly loose, it's held on by gravity or the wind cords, not by painful pressure on your forehead. - Adjustable, tuckaway, fore 'n' aft wind cord-It keeps the Hat on even while skydiving. No kidding - and not recommended! - Hydrofil anti-sweat band-It's soft, comfortable and helps to wick perspiration away from your forehead.
