Frequently Asked Questions
Are the Fitletic bottles insulated to keep ice all day?
No. The included 8 oz quick-flow bottles are lightweight plastic and not vacuum insulated. They’re built for fast access and low weight during runs, not long-term ice retention.
What size phone will the Hydra 16 pouch fit?
The main pocket is approximately 8 x 4 inches with an inner organizer; it fits most smartphones and cards, but very large phones or bulky cases may be a tight fit for some users.
Can I replace the bottles with insulated ones?
Possibly — but check the diameter of your insulated bottle against the quick-draw holster size. Most wide-mouth insulated bottles are too large for these holsters; for insulated carry consider an insulated bottle sleeve or a different pack designed for larger bottles.
