Your water or other hydration fluid will stay cooler longer in the double-wall, insulated 18-ounce flask while your smartphone tucks easily into the see-through touchscreen pocket. Headphone access at the bottom is another big plus.

But what we love most about this versatile carrier is that it includes Nathan’s award-winning SaferRun Ripcord Siren to deter a would-be attacker. Simply pull to activate a siren that’s as loud as an ambulance.

Futhermore, the hand sleeve lets you relax your hand for easy carry; no more gripping a water bottle on your pedestrian adventures!
