A weekend trip left me a solid believer in the virtues of Cocona fabric.  It’s made from from activated carbon from recycled coconuts and blended with other fabrics. My Savane pants (supposedly golf pants) pass as dress or casual khakis and I wore them for two days straight - almost wrinkle and odor free. Watch for this fabric. It seems ideal for travel. It’s touted as very fast-drying but I haven’t tested it yet in that respect. Pants (for men) are the hardest piece of the travel wardrobe to select. Polyester and microfber pants can get smelly in hurry in warm weather. Cocona may be the answer. This fabric will go with me next June for a warm-weather southern European trip. Stay tuned for more on Cocona.
