Gear Review: Sea To Summit TravellingLight Packing Cells

One of the keys to stress-free travel? Staying organized. These ultralight storage sacks, made from water-resistant and strong Ultra-Sil fabric, do the trick. They have a boxy, stand-up shape (thanks to stiffeners along the sides), which makes for easy rummaging, whether you’re looking for your favorite socks or a couple of loose ibuprofen tablets.

“I’ve used all three sizes on trips to Iceland, Vietnam, Chile, and countless domestic trips to keep my city clothes separate from my trail clothes, my carry-on bag organized, and my dirty laundry isolated,” says our gear editor. The mesh top makes it easy to see contents (it’s also available in a solid-topped version that’s great for toiletries), and a D-shaped zipper creates a wide-top opening for full and instant access. $18-$25; 2.2-3 oz.; seatosummit.com
