Description & Size guide

The Ruffwear Singletrak Pack is a great concept. This pack is great for high activity excursions with it's low-profile hydration pockets and is so comfortable that it allows the dog to stay agile. The idea of a fit and healthy dog carrying his own water, on a long walk, is perfect for our outdoor loving customers and their canine hiking, trail running or even mountain biking companions.

In hot conditions water from natural sources can become dirty and contaminated. Some dogs would prefer to go without which, on long walks and summer days, can be dangerous. With the Singletrak Pack this becomes no issue because the dog always has access to clean water.

Each soft sided water carrier slips into the pack and is BPA and taste free. The pack itself is fully adjustable for comfort using five separate alteration points. In addition foam padded belly and chest straps help to ensure a perfect snug fit. The Ruffwear Singletrak pack is lightweight which is perfect for summer day exercise and extended wear.


  • Oversized handle for easy lifting and assist

  • Two leash attachment points
    • Anodised Aluminium V Ring at front
