The UltraFlask 600 is a lightweight flexible drinking bottle from HydraPak. It weighs only about 50 grams, folds up easily and is ideal for carrying some extra water or drinks without packing a big bottle. When it is empty you roll it up and it takes no space. It works well in a running vest, in a hip belt pocket or under an elastic strap on your handlebar bag. The included drinking tube is a bit longer than usual, so you can drink without taking the flask out.
No plastic taste
The flask is BPA and PVC free, so your water does not pick up a taste. Tip for the first use: fill it with water, put it in the fridge for a day and any hint of taste is gone.
