My favorite travel hack: Wool shirts and wool socks. They need washing less often so you pack less clothing. And, showering with hand-sanitizer on arm pits. https://www.woolly.clothing/collections/190-gsm-shirts/produ... https://unboundmerino.com/collections/socks https://www.smartertravel.com/unbound-merino-womens-v-neck-r...
Moreover, when you wash them, they take longer to dry.
