For eighteen months of travel, I had me, myself, and I — plus two bags. As a self-proclaimed collector of things and trinkets, becoming a minimalist was definitely a learning curve. Limited by weight and custom declarations, I quickly became an expert of multitasking beauty products, techy gadgets that make life (and work) easier, and wardrobe staples that function well, sans wrinkles. After more than 100 flights — and mastering the packing-unpacking-packing routine — I developed deep loyalties to specific products and brands. After all, when you’re in the midst of the chaos that often comes from an unpredictable life on the road, having the right carry-on bag, external battery, pair or kicks or tummy meds, can make or break your day in a new city.

So, when in doubt, I always ask the pros what to pack. Travel influencers who share their treks with thousands (or millions!) have discovered the most effective and reliable gear and goods out there. Here, they share the travel accessories they never, ever leave home without.
