Hydrate without breaking stride.
The HF-01 carries your fluid, phone and gels locked to your chest — one adjustable fit, no bounce, from a 5K to a full Hyrox floor.
Every water stop costs you the race.
You stop to drink
Twelve seconds at a station, four stations deep, and your pace curve never recovers.
Cheap packs bounce
A loose harness turns every stride into slosh, and slosh turns into chafing by kilometre six.
Race vests cost 150 and up
The brands with the right fit price it like a race entry. You shouldn't have to choose.
Four things that make it disappear on you.
Shoulder ladders and a waist buckle, both adjustable.
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
1 litre you can reach at full pace.
Two 500ml soft flasks sit high on the chest, in reach of your mouth. They collapse as they empty, so the weight goes away instead of sloshing around behind you.
- Both flasks included, BPA-free
- Wide mouth for ice and electrolyte tabs
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
Against everything else you've tried.
Train in it for a month. If it moves, we refund it.
Not "unworn, tags on". Actually run in it — road, treadmill, sled, whatever. If it isn't right after 30 days, we pay the return and refund in full.
- Full refund, no restocking fee
- Prepaid return label, worldwide
- Free colour swap, once, on us
- 1-year hardware warranty on buckles and zips
Before you order.
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?
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?
Yes — two 500ml BPA-free soft flasks ship in the box. Nothing else to buy.
Can I wear it for a Hyrox event?
Plenty of our customers do. Check your event rules first — some races restrict what you can carry on the floor.
How long is shipping?
Dispatched within 24 hours, tracked, free worldwide. Most orders land in 5–8 business days depending on destination.
What if it does not work out?
Train in it for 30 days. If it is not right, we email you a prepaid label and refund in full — worn is fine, that is the whole point of the test.
