Rain or shine you will be ready without sacrificing space in your day pack. Nothing can ruin a day out as much as rain. But bad weather doesn't have to spoil your fun! Just toss in a micro umbrella and keep on going.
Travel Gadget Pro TIp: Locals know the weather patterns. They will set up stalls on well travelled tourist areas with umbrellas on particularly sunny or rainy days, then rip off tourists by selling them a full size umbrella for 10x what they really cost. Save yourself the hassle!
