Xact Carb Scaled Soft Flask

Measure Your Carbs. Keep Running.

Best For: Trail running, ultramarathons, fastpacking, and long training sessions when you want to measure and carry a precise amount of carbohydrate fuel without mid-run guesswork.

Take the math out. The Xact Carb Scaled Soft Flask uses clear carbohydrate markings at 30 g, 60 g, 90 g, 120 g, and 150 g so you can measure your fuel before the run and check what's left at a glance. With roughly 200 ml of capacity, it offers a compact way to carry concentrated endurance nutrition in a running vest or fastpacking setup.

Built for easy fuelling. The soft, squeezable body makes it simple to portion and dispense bulk gel while you're moving, even on technical terrain. It's designed around Xact Bulk Gel servings, with capacity for up to five full servings, and  can also be used with bulk gels from other brands.

Ready for long seasons. Reusable and BPA-free, the flask is made to be washed and used again rather than treated as single-use race-day packaging. Keep it in your vest for long runs, races, and self-supported adventures when knowing exactly how much fuel you're carrying matters.
