Fuel carrying made simple.

The XACT Soft Flask holds exactly 150g of carbs from our Bulk Gel Pouch, marked with a carb scale so you know exactly how much you're packing. 30g, 60g, 90g, 120g, 150g. Fill to your target. Go.

Built for precision.

Unlike standard soft flasks with vague volume markings, ours is scaled in carbs—the metric that actually matters. Fill to the 60g mark and you know exactly what you're carrying. No guessing. No math mid-effort.

Designed for our bulk gel.

The carb scale is matched to XACT Bulk Gel portions, so filling is intuitive. One soft flask = 5 servings. Two flasks = 10 servings. Three flasks = your entire weekly pouch. The fit is perfect.

Easy squeeze. Reusable. Durable.

Squeeze cleanly without spillage. Hand wash between uses. BPA-free, recyclable when it's done.
