Lunidry Hydration Backpack 3L Bladder — 15L Lightweight Insulated Pack

Lunidry Hydration Backpack is a lightweight 15L pack with an insulated 3L water bladder designed to keep drinks cool and hands-free on runs, rides, and hikes.

Whether you’re covering miles on trail runs, pacing a long cycle, or day-hiking, this Lunidry hydration pack combines a 3-liter leakproof bladder, an insulated sleeve that preserves chill, and organized pockets in a compact 15-liter frame. Built from PU-coated, tear-resistant nylon with breathable padding and adjustable straps, it balances water capacity, storage, and comfort for active outings.

How does the 3L bladder perform for long outings?

The included 3L bladder is made from BPA-free, food-grade PEVA and features a wide 2-inch opening for easy filling, ice insertion, and cleaning. A leak-resistant seal and accessible drinking tube let you hydrate without stopping, and the insulated compartment helps slow temperature rise for several hours.

• 3L capacity holds longer hydration between refills
• 2-inch wide-mouth opening for ice and easy cleaning
• BPA-free PEVA material for safe drinking storage
• Insulated sleeve helps keep liquids cooler on warm days

Will this pack stay comfortable during runs and rides?

Lunidry designed the pack for active movement with multiple adjustable straps, breathable mesh padding, and a slim 15L profile. The shoulder, chest, and waist straps can be tuned to reduce bounce, and the back panel’s ventilation helps limit sweat buildup during sustained effort.

• Padded shoulder straps with breathable mesh for airflow
• Adjustable chest and waist straps to minimize bouncing
• Contoured back panel for stability and comfort
• Lightweight construction reduces fatigue on longer sessions

How much gear and organization does the bag offer?

This hydration pack includes several compartments to separate hydration from essentials: two zippered pockets for clothing or snacks, a mesh side pocket for small items, and twin hip-belt pouches for quick-access valuables. The layout keeps heavier items close to your back for balance while giving easy reach to items you use frequently.

• Main insulated bladder compartment keeps water and cooler separate
• Two zippered pockets for layers, maps, or tablets
• Mesh pocket for towel, umbrella, or quick-grab items
• Two waist pouches for phone, keys, or energy gels

How durable and easy to maintain is the pack?

Constructed from PU-coated nylon, the Lunidry pack resists tears and light moisture, making it suitable for trail and urban use. The bladder’s wide opening speeds cleaning and drying—turn it upside down to air dry naturally—and Lunidry offers one-year replacement support for qualifying defects.

• PU-coated nylon for water resistance and tear strength
• Bladder’s wide mouth simplifies cleaning and ice addition
• Turn bladder upside down to air dry after washing
• One-year replacement service for quality concerns

Who is this for?
