Nathan Hypernight QuickStart 4L Hydration Pack – 1.5L Bladder, Reflective Night Visibility, Front Bottle Pockets

All-in-one hydration on the move

Meet the Nathan Hypernight QuickStart 2.0 4 Liter Hydration Pack. It combines a compact design with a generous 4 liter capacity and a 1.5 liter bladder, letting you stay hydrated while keeping essential items close at hand. Its lightweight build and thoughtful storage mean you can focus on the trail rather than fiddling with gear.

Materials and comfort are front and center. The blend of 60% Nylon and 40% Polyester delivers durability without bulk. A moisture-wicking stretch woven fabric and chafe-free binding minimize irritation, while breathable mesh shoulder straps help you stay cool as you move. The pack includes two easily accessible front pockets for quick snacks, keys, or a phone, plus a main back pocket for a light layer or additional gear. A dedicated front bottle pocket accommodates up to a 22 ounce flask, making hydration feel effortless at a glance.

One size fits most and adjustments are simple. Front and side straps let you dial in the fit for your torso and stride, so you can run, hike, or stroll with confidence. The total weight with the bladder is about 12 ounces, and 7 ounces without the bladder, giving you a light feel on long days.

Real-world use ideas. On a sunlit trail, you can slide snacks into the front pockets, keep your phone accessible for navigation, and sip from the front bottle pocket without stopping. In city evenings, the reflective elements help with visibility while you cruise a lighted path. For longer sessions, the 1.5 liter bladder provides steady hydration without having to carry a heavy backpack — a little extra fuel can make a difference mile after mile.

Care and maintenance. Hand washing is recommended, and Nathan Power Wash can help keep the pack looking fresh. To clean the bladder, remove tubing and bite valve, rinse thoroughly, turn the bladder inside out, and air dry standing up. Regular care helps preserve the fabric, pockets, and zipper performance so you can rely on this pack again and again.
