Fitly Sub180 Adventure Running Pack Hydration Vest - Blue - Trail Running Water Vest - 4 Pockets, 1.1L Bladder, 250ml Soft Flask - Anti-Sway Vest for Men & Women - Running Gear One Size Fits All

THE ADVENTURE RUNNING PACK: With a focus on high-end components, physics and aesthetics, FITLY has crafted the perfect running pack for sub-180 runs. Carry small personal items without being weighed down. Boasting 4 pockets, two flasks, silent zipper tabs and plentiful room for your belongings, our unisex hydration running vest makes carrying your personal items & maintaining your running form perfectly compatible. HIGH-DURABILITY HONEYCOMB FABRIC: Using high tenacity fibers, FITLY's running pack's fabric is exceptionally durable and puncture resistant. Featuring high-durability honeycomb fabric, used in high-end mountain guide equipment, our running hydration vest for men and women is made to endure the toughest conditions. Our running pack's sternum straps are adjustable, wide and soft to disperse the weight and increase the feeling of snugness. SOFT FLASK & BLADDER INCLUDED: We have included two hydration facilities in our running pack. A 1.10 L - 37 oz ingeniously designed soft bladder and a 250 ml - 8.5 oz - soft flask in the front pocket. Contrary to traditional bladders, our running hydration pack's bladder is super thin and malleable to fit your body contours. It shrinks as you drink, reducing sloshing and is so thin, it is barely noticeable, perfect for running. 4 POCKETS & AMPLE STORAGE: Our trail running pack possess a huge massive capacity. It boasts a mighty 4 liters back pocket to carry the bulk of your load with stretch panels that increase the pressure on personal items to prevent excessive movement. Our running pack also has a full-length pocket, stretch pocket and bladder pocket. HEAT DISSIPATION VENTS & ANTI-SWAY FOR INCREASED COMFORT: Located at the top of the shoulders of our hydration pack running vest, the heat vents provide cooling where heat accumulates ensuring you stay cool during runs. We have designed our trail running vest to be anti-sway. The soft upper webbing latches onto the back of the running pack. The pulling forces push the pack towards the runner's back drastically reducing the left-right swaying common in most other well-filled running packs.
