ExOfficio shirts give you all the features you know you want in a shirt and then throw in a few more. Stain and wrinkle resistance are important when you travel. Lightweight and packability are on the list, too. But how about an indestructible button system and moisture wicking for comfort in high humidity? Some ExOfficio shirts even build insect repellent and odor resistance right into the fabric. Special venting systems keep you cool in the noonday sun. Wherever your travels take you, an ExOfficio shirt should be on your back.
