Going for a run in the park or on a trail? Wear the Runtasty Running Mini Backpack Vest to keep your gear with you comfortably. This slim backpack measures just 0.2 inches thick and expands to hold any smartphone—even in a bulky case. This runner’s vest has two pockets for you to organize your essentials. And the larger pocket can hold a tablet under 8.5″ in size. Instead, you could pack a water bottle up to 16.9 ounces. Thanks to its bounce-free design, this unisex running vest can successfully replace a waist running belt and is great for other activities such as cycling, walking, and climbing. The ventilated, breathable back won’t make you uncomfortably sweaty. Furthermore, its water-resistant material can handle light rain, humidity, sprinklers, sweat, and splashes. Due to its light weight and low profile, this backpack vest streamlines your gear, letting you embrace a worry-free, minimalist lifestyle.
