Two Liters. Zero Hands. Every Mile.
The Optmzd™ Hydration Vest carries a 2L BPA-free reservoir flat against your back, with the drinking tube routed to your shoulder, so you sip mid-stride without slowing down, stopping, or carrying anything in your hands.
Adjustable chest and side straps lock it to your torso for a true zero-bounce fit, breathable mesh panels keep heat moving out instead of building up, and front pockets hold your phone, keys, and gels right where you can reach them. Lightweight enough to forget, secure enough to race in.
Fill it. Strap in. Run like the water isn't there.

Frequently Asked Questions
Does it come with the water bladder, or is that sold separately?
Does it come with the water bladder, or is that sold separately?
It's included. Every vest ships with a 2L BPA-free hydration bladder pre-fitted in the back sleeve, with the drinking tube already routed to your shoulder. Fill it, clip in, and go — nothing else to buy.
Won't it bounce around while I run?
Won't it bounce around while I run?
No — that's the entire reason it's a vest and not a pack. The load sits high and flat against your spine, and the adjustable chest and side straps compress it to your body. Once it's dialed in, the vest moves as part of you, not on top of you.
How is this different from just wearing a small backpack?
How is this different from just wearing a small backpack?
A backpack hangs from your shoulders and swings with every step — which is fine for walking and miserable for running. This vest distributes weight across your torso, breathes through mesh panels instead of trapping sweat, and puts your hydration and pockets within reach without taking anything off.
Will it fit me? What sizes are there?
Will it fit me? What sizes are there?
The harness is fully adjustable at the chest and sides, so one vest fits the vast majority of body types — men and women. Tighten it down for a race-day lockdown fit or loosen it over a jacket in colder months.
What can I actually fit in the pockets?
What can I actually fit in the pockets?
The 2L bladder rides in back. Up front you have room for a large phone, keys, cards, energy gels, and small essentials — everything positioned on your chest so you can grab it without stopping or taking the vest off.
How do I clean the bladder?
How do I clean the bladder?
Rinse it with warm water after runs, especially if you've used electrolyte mix, and let it air-dry fully with the cap open before storing. The vest itself can be hand-washed and air-dried.
Is it only for running?
Is it only for running?
No. It's built for running first — that's the hardest use case to get right — but the same zero-bounce fit works for hiking, cycling, ruck walks, festivals, and travel days. If you're moving for more than an hour, it earns its place.
