Hardside Hydration Swig Cap Ultralight 28 mm

This Hardside Hydration Swig Cap Ultralight 28 mm is an ideal accessory for PET single use bottles such as water, soft drink and juice bottles. Pair this with your favourite existing hydration hose (from your busted bladder), a Hardside Hydration Hose kit or even the On-the-go kit (great for sports such as boxing)

*If you're using a hose from another hydration system that seems a little stretched out, it may need to be trimmed to create a tight seal with the cap.
