These lightweight and low-profile packs are perfect for those rides where you need to take more than just a water bottle. The packs have a dedicated hydration compartment and come with either a 1.5, 2.5, or 3L Hydrapak reservoir included. The Airscape back panel uses air mesh-covered foam with a centre air channel for excellent ventilation, and the Biostretch harness is lightweight and ventilated and has rolled soft edges that contour to the shoulder for comfort and stability. The sternum strap has a magnetic attachment to make hose management a breeze, and there is a light attachment to attach a rear light if you need to commute home in the dark.

Who's this item for: The Katari is the Men's version of this pack but it is perfect for anyone looking for a lightweight and low-profile hydration pack with a quality reservoir. Also, check out the Kitsuma for the Women's model with female-specific fit and sizing.

Strap Style: The pack uses Osprey's Biostretch Harness which are ridged airmesh straps with soft rolled edges for breathability and comfort.

Materials: 100D nylon main body with a 600D polyester bottom.

Hydration bladder capacity / Bladder style / Valve style:

• Available in 1.5, 2.5, and 3L bladder options.
• The Osprey Hydraulics reservoirs are made by Hydrapak so they are among the best you can get. The reservoir seals by folding over the top and sliding on the slide seal. This creates a reliable watertight seal but also makes it easy to open the top right out when filling or cleaning the bladder.
• The Blaster bite valve provides fast water flow and can be locked off with a 1/4 twist switch.

Helmet carry: No, these packs do not have that feature.

Internal organiser pockets: The Katari 7 features a vertical zip compartment on the front with tool organisation. The smaller models don't have much in the way of internal organisation.
