formation of black layer on the blue rubber cap

Bottle is good but there is formation of black layer on the blue rubber cap. And that looks horrible. Tried to clean it but it won’t come out.

Excellent Product

Excellent product

Flimsy cap, sturdy bottle

The cap/mouthpiece for this bottle cracked on the second day of use. The meant there was no seal to the bottle and had to be binned. This was very frustrating as i was at the start of a 2 week hike, on minimum equipment and even less after this bottle broke!

Excellent Water Bottle

Very easy to carry and used.

Love the opening for drinking and the refill unscrew. Unfortunealty lost the silicone washer in the cap when refilling one day (after 2 month of use). Blue plastic handle broke free of the plastic rings (Picture if needed)

Directions for use

Aluminum is not an insulating material. Use a specially designed, insulating cover if you want to keep liquids cool in your flask. This flask can be used for hot drinks but they will cool quickly. Do not use with carbonated drinks, fatty substances (dairy products, oils...) or acidic drinks (fruit juices, energy drinks). Do not put in microwave or freezer; do not expose to naked flames or other heat sources.


The top has a handle that enables easy transport in your hand or hang it from a rucksack with a strap or snap hook.

Care instructions

Clean your flask after each use with conventional dish soap and water. The product can also be placed in the dishwasher if necessary. Caution: when placed in the dishwasher, the seal stopper may come off. Make sure you put it back if this happens, to ensure the water tightness of your flask. Allow the cap and bottle to dry separately.

First time use

Rinse the entire product 3 times with clean water before using it for the first time.
