Endurance Pack V3.0: Ideal for running, triathlon, mountain bike and gravel biking
Endurance Pack V3.0: Rock-Solid Stability for Running & Biking
The 2L HydraPak Elite bladder is in the box, not a $35 add-on. One price, ready to run: vest, bladder, quick disconnect, and pockets for two soft flasks up front. Designed for runners, cyclists, and triathletes who demand zero bounce and all-day comfort, this hydration vest delivers a secure fit, breathable construction, and intuitive storage—so you can focus on the effort, not your gear.
4.9 stars across 168 reviews, and the same fit system as the vest our customers have run hundred-milers in.
It doesn't bounce.
The Endurance Pack V3.0 sets the standard for locked-in comfort across long miles:
- Zero-Bounce Fit: Dual front adjustments and a sternum harness lock the pack in place, virtually eliminating movement.
- Fits Most Athletes: Adjusts to fit up to a 44" chest — and if you need more room, we alter it free. See below.
- Adaptive Comfort: Non-stretch front straps paired with elastic side webbing accommodate breathing while maintaining a secure, no-slip fit.
- Breathable Construction: Lightweight, airflow-focused materials help manage heat during long efforts.
Doesn't fit? We'll alter it, free.
If you're a larger runner and this pack doesn't fit the way it should, send it to us and our staff seamstress will modify it to fit you at no charge. Straps, torso length, closures. We do a few of these every month and we have never charged for one.
You shouldn't have to guess whether a vest will fit before you buy it. Order your size, run in it, and if it needs adjusting, email sales@orangemud.com. Either way you're covered by our 30-day return and 365-day warranty.
