Silva Soft Flask – Flexible TPU Flask with Integrated Drinking Straw

The Silva Soft Flask is a flexible flask that carries water or sports drink and rolls and squeezes down as you drink. It comes in 250 ml and 500 ml sizes, and a 500 ml model adds an integrated straw so you can sip without unscrewing a cap.

Fill it, tuck it into a hydration vest pocket, and drink on the move. The flask is soft and lightweight, which makes it comfortable to carry on runs, hikes, and long days on your feet. It is made from flexible TPU that Silva states is free of BPA, phthalates, and PVC.
