ROCKBROS 620ml Insulated Cycling Water Bottle – Thermal Triple-Layer Squeeze Bike Bottle with Silicone Nozzle

Stay Cold on Every Climb. The ROCKBROS Thermal Cycling Bottle.

The ROCKBROS 620ml insulated cycling water bottle is built for MTB, road cycling, and outdoor sports where staying hydrated — and staying cool — matters. Triple-layer insulation (PP body + polyethylene foam insulation layer + food-grade silicone nozzle) keeps your water cold for approximately 5 hours on the ride. The 7.4cm diameter fits most standard bike bottle cages. Squeeze to drink, leak-proof cross valve prevents drips when inverted. 90-day warranty. Available in multiple colorways.

⚠️ Recommended water temperature below 70°C. Not a full vacuum thermos — insulated for cooling, not long-duration heat retention.
