Camelbak Thermobak 3L Short Mil Spec Crux


The ThermoBak S3L offers the same features and functionality that warfighters have come to trust in the ThermoBak 3L, but in a new design that optimizes the space on a users back and won’t interfere with a duty belt.

The 3L, 100oz Mil Spec Crux reservoir delivers 25% more water per sip and the external fill allows quick access to the reservoir for refilling and cleaning.

– Fully insulated reservoir compartment using 5 mm closed-cell foam
