UltraFlask® X Hydrapak 150ml

Most flasks carry gel. Ours doses it. Developed with Hydrapak and custom-graduated by Pyrène, the UltraFlask 150 ml allows you to easily portion your carbohydrate load, without equipment or mental calculation. The protocol thus becomes a reading of the product level remaining in the flask.

Compact and compressible, it slips into a vest pocket, folds up as it empties, and doesn't bounce around. Its wide-opening silicone valve lets through thick gels as well as liquids, and its clip-on cap keeps the spout clean between uses. A single reusable container instead of several sachets: less waste, more autonomy.

Highlights

• Exclusive Pyrène graduations: precise dosing without a scale
• Flexible and compressible: folds up when empty, stores anywhere
• Wide-opening silicone valve: for thick or liquid gels, even in motion
• Reusable, BPA and PVC free
• Hand / pocket size: trail, road, gravel, triathlon suit

Features

• Capacity: 150 ml (up to ~3 gel doses)
• Materials: TPU, polypropylene, and POM — BPA and PVC free
• Graduations in grams of gel corresponding to the quick gel dosing chart

Tip: fill your flask with the dose calculated by our calculator (or your Metabolic Scan), and let the graduations do the rest.
