Crux Insulated Tube

This tube is compatible with any CamelBak reservoir that features the Quick Link system. If your current reservoir has a tube that clicks in and out of the base, it will work seamlessly.

The thermal sleeve significantly slows down the freezing process, making it effective for most winter activities. However, for extreme, prolonged exposure to sub-zero temperatures, you should still blow water back into the reservoir after each sip to clear the tube.

Hydroguard is an antimicrobial treatment embedded into the tube material itself. It inhibits the growth of bacteria and mold, which helps keep your water tasting fresh and reduces the frequency of deep cleanings.

Yes, the Big Bite Valve can be easily removed from the tube. We recommend detaching it periodically to rinse it out and ensure no residue builds up inside the silicone tip.

The sleeve adds a slight amount of thickness compared to a standard, non-insulated tube, but it remains flexible and lightweight. It is designed to route through standard pack shoulder straps without restricting your movement.
