A closer look at the High Sierra Piranha hydration pack

2-liter hydration system

At the heart of the Piranha is an antimicrobial and BPA-free hydration system with 2-liter capacity for longer races or higher treks. Its reservoir opening accepts water filters, and fully opens at the top to fit your hand when cleaning.

With the larger aperture, you get to spend more time on the road and less time on refills. The reservoir seams are double welded for durability, but in case they leak, the fold-and-slide closure works together with the separate reservoir to protect your valuables from spillage.

Plus, this hydration system is winter-friendly, made possible by the insulated tube cover that prevents the water from freezing in the cold.

Versatile compartments

This High Sierra Hydration Pack will keep your stuff organized and easy to find. It features a front pocket organizer that allows quick access to accessories like gloves and arm sleeves. The stretch compartment includes a convenient key fob so you won’t have to rummage through your things to find them.


There’s also a zippered mesh pocket in the trunk to hold your wallet, smartphone, and other essentials. For peace of mind, this can only be accessed by unzipping the main compartment, thus keeping your valuables safe and secure. And once you get off the bike, you may simply stow your helmet in the pull-out mesh cover at the bottom of the pack.

Durable and lightweight

High-Sierra-Piranha-hydration-pack-4aThanks to a 10-liter storage capacity, the Piranha pack offers plenty of space even on a full bladder. It will let you fit a rain jacket, spare tubes, bike tools, and more than a few snacks – with room to spare. Weighing in at only 1.9 pounds when empty, this hydration pack is a featherweight for its size.

No need to worry about running on a full load either, because it’s made with a 300 by 250-denier Duralite fabric with water-resistant hexagon rip-stop. This helps wick moisture away and prevent cuts from tearing all the way through, so you can run with confidence.

Other features

Whether it’s full or empty, the High Sierra Piranha pack fits the body nicely, and stays well-balanced as you move. This is owed to the adjustable side compression straps and sternum strapHigh-Sierra-Piranha-hydration-pack-6a that assists in stabilizing the load.

These can also be used for storing trekking poles in tandem with the gear loops at the bottom. If you’re planning to use the pack for running, or simply dislike straps flying about your waist, then you may take off the waist belt in a snap.

For safety, there’s a sizable exterior reflective loop that provides the perfect setup for a bike LED blinker. Additionally, it features an exclusive Add-a-Bag strap, which means you can carry two bags simultaneously using a clip-on strap.
