How We Researched the Best One Strap Backpack
Best One Strap Backpack 3 Features That Make One Strap Backpacks Special
1. Single Strap
Unlike traditional backpacks, which have two straps, sling backpacks are only made with one strap. They’re crafted with ergonomics in mind. One strap backpacks are designed with padding along the back and strap for an easy carrying experience. They are also engineered to evenly distribute the load so that the bag sits comfortably against the wearer’s shoulder and back.
2. Petite Size
Single strap backpacks are smaller than their two-strapped cousins because carrying a lot of weight on just one shoulder over long periods of time can be uncomfortable. For this reason, one strap backpacks are used to carry small essentials, rather than heavy gear like electronics and water bottles. Sling bags are ideal for travel and outdoors activities.
3. Strategic Pockets
One strap backpacks maximize their small capacity with strategic pockets and compartments. The backpacks on this list have great features like strap cell phone pockets, hydration bladder pouches, protective sunglasses pockets, and even concealed-carry sleeves.
