Super Portable

HYDROPLATES™ are fully collapsable and light when emptied. Slide them in your luggage to train on your vacation!

Home Workouts

Perfect for home workout., train at home without worrying about metal plates that can damage your home and take up space!

Variable Weight

Unlike metal, water is liquid which means you adjust the weight by filling up the hydroplates accordingly!

Patent-pending water weights

The heaviest thing you’ll never pack.

Weight plates have one flaw: they weigh something. Hydroplates leave the house at 0.9 lb, flat and collapsible — then borrow up to 35 lb from the nearest tap when you arrive. The weight stays behind. The training doesn’t.

The trick metal can’t do

Pour your weight.

~9 LB Quarter

~17 LB Half

~26 LB Three-quarter

35 LB Full

A steel plate is one weight forever. A Hydroplate is every weight from 0 to 35 lb — pour to the load today’s session calls for, top it up as you get stronger. (Fill weights approximate.)

01 · Travel-ready

Packs flat. Fills fast.

Empty, each plate is under a pound and fully collapsible — it slides into luggage next to your laptop. On arrival, any tap brings it to working weight in under a minute.

0.9 lb in your bag — lighter than most toiletry kits
Under 60 seconds to fill — and just as quick to empty
2 plates + 2 acrylic clamps included in every set

02 · Fits your gear

A real plate, as far as your bar knows.

The 2″ (50 mm) bore loads onto any Olympic barbell and the EZ-VEST — and with a bumper plate sleeve you can stack two per side for up to 66 lb (30 kg) on the bar.

Olympic barbells — squats, presses, and rows on the road
EZ-VEST — weighted calisthenics anywhere there’s a bar
11″ (36 cm) diameter — full-size plate footprint when filled

03 · Home-safe

Weight your floors won’t feel.

Metal plates and apartments are a bad marriage: dents, noise, and 35 lb of steel to store. Hydroplates are soft-sided and water-filled — kind to floors, quiet to set down, and they collapse flat into a drawer when you’re done.

The suitcase test

Packing steel vs. packing water.

A 35 lb plate in your luggage

35 LB

There goes your entire baggage allowance — for one plate. Rigid, heavy, and the same weight on the way home. Nobody has ever done this twice.

A Hydroplate in your luggage

0.9 LB

Flat, collapsed, lighter than your shoes. The 35 lb is waiting in the hotel tap — borrow it for the session, pour it back, fly home light.

Water is everywhere

Your weight room is any faucet.

The Sink

Hotel bathroom, kitchen tap, gym fountain — a minute per plate and you’re loaded.

The Hose

Backyard sessions with full-size plates that live in a drawer between workouts.

The River

Park calisthenics with real load — fill at the water, train at the bars, empty and jog home.

Before you buy

Questions, answered.

What’s included?

Every set ships with two Hydroplates and two acrylic clamps to lock them onto the sleeve. Each plate has a 2″ (50 mm) Olympic bore and an 11″ (36 cm) outer diameter when filled.

How much weight can I get on a barbell?

Each plate holds up to 35 lb of water, adjustable from zero by how much you pour in. Using a bumper plate sleeve, you can stack two Hydroplates per side for up to 66 lb (30 kg) total on the bar.

Can I take them on a plane?

That’s the whole idea — travel with them empty. Collapsed, each plate weighs 0.9 lb and lies flat, so it packs like a folded T-shirt in carry-on or checked luggage. Fill on arrival, empty before you leave.

How long does filling take?

Under a minute per plate at a sink, hose, or any other water source — and since the weight is just water, you can stop pouring at exactly the load you want.

What if they’re not for me?

Every order is covered by the 100-day risk-free trial. Take them on a trip or two; if they don’t earn a permanent spot in your bag, send them back — no questions asked.
