Long-distance running of more than a few miles requires hydration and oftentimes a bump of energy gel. Running belts meet that need, but most of them are too bulky and cumbersome to be practical. Now French label Satisfy has made a Spartan but truly useful running belt that packs what you need and leaves behind what you don’t. Made with 4-way stretch, fast-dry, and wicking double-layered Justice material from France, the belt has pockets for two water bottles, two gel packs, a smartphone, and two sets of keys with securing rings and lanyards. Their lightweight pouch water bottles are included, and the entire set should keep you going for miles unless your lungs and legs give out first.
