Buy the Men's Puckerware Shirt locally. The cut-rate bus trip from Hanoi can have you soaked to the bone well before you've made it to the deep water solo routes of Ha Long Bay. An all-time favorite for travel in hot and humid weather, the Puckerware short-sleeved shirt keeps you cool and comfy through muggy days on the road. Constructed with a textured 65% recycled polyester/35% organic cotton seersucker blend, the crinkled weave stays breezy and lifts away from the skin, allowing air to circulate and moisture to dissipate. It also resists wrinkling, washes easily and dries in a moment. With button-through left-chest pocket, side vents and straight hem.
