The Crux Thermal Control Kit helps prevent the drink tube from freezing in winter and keeps water cool in hot summer conditions. It features a thicker neoprene sleeve and a more insulating mouthpiece cover. We recommend pairing it with your CamelBak pack or reservoir.
Includes:
- 110 cm antibacterial PureFlow drink tube with thermal insulation sleeve
- CamelBak Big Bite Valve mouthpiece
- Insulated Bite Cover cap
The QuickLink connector makes attaching and detaching easy with CamelBak Crux and Antidote reservoirs. Covered by a 2-year warranty against material and manufacturing defects.
Tip: In hard frost, give the tube a short blow after each drink - an empty tube does not freeze as easily as a full one.
