500ml scRUNch Flask - With Straw
Stick it in your bag, flip the lid, sup it, scrunch it. This one’s virtually bombproof and built for Ultras, multisport, biking and any outing where fast, fuss-free hydration makes all the difference.
We’ve widened the opening to make filling even easier—whether you’re dropping in ISO tablets, scooping powder, or topping up on the move. No spills, no faff, just grab, fill, and go.
As you drink, the flask shrinks down, saving valuable space in your pocket or pack. With the long straw option, it’s perfectly at home in a front vest pocket, especially with the Great Glen 15 Multi-Sport pack. And with handy measurements on the rear, you can keep tabs on exactly what you’re taking in when the miles start to rack up.
