Every water stop costs you the race.
01 — LOCK-DOWN HARNESS
Four things that make it disappear on you.
Slide the shoulder straps and cinch the waist and the load sits on your ribcage instead of hanging off your shoulders. Set it once, forget it for 20km — no size to choose, no fit to get wrong.
- No shoulder pressure points
- Adjusts over a bib, singlet or jacket
02 — BACK HYDRATION
2 litres you can reach without breaking stride.
The 2L bladder sits flat against your back in the mesh panel, with the hose clipped at your shoulder so a sip is one hand away. As it empties the weight settles low and centered instead of sloshing.
- 2L leak-proof bladder included, BPA-free
- Wide-mouth fill cap for ice and electrolyte tabs
03 — 5L OF ORGANISED CARRY
Zip pouch, bungee deck, key clip.
A large phone goes in the main zip, gels in the slim front pocket, and a shell or gloves under the bungee deck. Everything sits flat against the chest instead of swinging on your back.
- Water-resistant coated shell fabric
- Reflective zip pulls front and back

Solid vest, slow delivery
The hydration setup is exactly what I needed for marathon training. Taking away one star because standard shipping took 9 days, but the vest itself is flawless.
-
Zero bounce, perfect fit
Was worried it wouldn't fit my chest right, but the adjustable straps lock it in perfectly. The material feels premium and it doesn't rub or chafe at all during a 10K.

"…water days are back for my senior boy."
Texas heat is no joke
Having quick access to fluid strapped to my chest makes a huge difference. Highly recommend if you run in direct sun or high heat.

FAQ
Before you order.
Will it bounce when I run?
Will it bounce when I run?
Not once it is cinched. The shoulder ladders and the waist buckle pull the load onto your ribcage rather than letting it hang, so it stays flat through interval pace and sled work
Do I need to pick a size?
Do I need to pick a size?
No. It is one adjustable fit — the shoulder straps and waist strap cover most torsos, and you can adjust it over a bib, a singlet or a winter jacket.
Are the soft flasks included?
Are the soft flasks included?
Yes — two 500ml BPA-free soft flasks ship in the box. Nothing else to buy.
Can I wear it for a Hyrox event?
