HydraPak hydration reservoir Hydrasleeve 3 L bladder for backpacks, 3-litre capacity

HydraPak Hydrasleeve 3 L bladder for backpacks is a lightweight hydration reservoir designed to fit inside a wide range of daypacks and multi-day backpacks. The 3-litre capacity offers extended water supply for hiking, cycling and travel while the hydration sleeve design simplifies installation, removal and handling. The bladder is made for practical on-the-go hydration and facilitates refilling and cleaning without altering the pack setup.

Advantages

The Hydrasleeve bladder combines a slim, flexible profile with low weight to maintain pack comfort and balance. Its sleeve-style shape helps secure the reservoir inside a dedicated pocket and reduces movement while you walk or ride. The 3 L volume gives a balance between capacity and pack space, allowing longer outings without frequent refills. Materials and construction are chosen for repeated use, and the design supports easy access to the reservoir for cleaning and drying.

• Day hiking and multi-day trekking where a 3-litre supply is appropriate
• Cycling and mountain biking with hydration routing to a drinking tube
• Travel and commuting when hands-free, on-the-move hydration is required
• Outdoor activities that require a lightweight, pack-integrated water source

How to use

Open the reservoir according to the manufacturer’s filling method, fill with potable water and close securely to prevent leaks. Slide the Hydrasleeve into the backpack hydration sleeve or dedicated pocket so the reservoir sits flat against the pack back. Route the drinking tube through the pack’s exit port and secure the tube along shoulder straps using available clips or attachments. Refill as needed during activities and follow cleaning instructions after each trip to avoid buildup or odors.

Usage recommendations

Flush the bladder with warm water after each use and allow it to dry fully before storage to prevent bacterial growth. Avoid freezing liquids inside the reservoir unless specified as safe by the manufacturer, and inspect seals and connections regularly for signs of wear. Use only potable water and compatible cleaning products to maintain material integrity and hygiene.
