The belt’s external mesh pockets are waterproof, protecting electronics from mud and rain.

Buying considerations
What to consider
When selecting a hydration belt, start by assessing the amount of water you need for your typical activity. Longer runs or rides benefit from a larger bladder (4‑5 L), while shorter sessions are well served by 2‑3 L capacities that keep the belt lightweight. Fit is critical; look for adjustable, breathable straps that sit low on the hips to reduce bounce. Material matters - BPA‑free TPU or silicone bladders resist leaks and are easy to clean, while reinforced walls add durability for rough terrain. Finally, consider extra storage - pockets for gels, phones and keys can eliminate the need for additional gear, making the belt a more versatile companion.
