Expected very little. Magnets plenty strong for keys, phone and a 500 ml bottle. Loses a star for the lead time.

Why it exists

Nothing on the floor. Ever again.

Locks to the rack. Your bottle, phone and keys stay at hand height, not in the sweat and chalk on the floor.

Will it really hold?N52 magnet. Holds a 10 lb plate on any steel rack.
Will it wipe my cards?No. It sits in the base, far from the pocket.
Is my phone too big?Pro Max with a case slides right in.
Will it get gross?Sweat, chalk, spills. Wipe it and go.
Nothing on the floor. Ever again. Hold test
10 lb.Bottle, phone, keys, wallet. Then we hung a plate on it.

Bought on an impulse and expected very little. Two weeks later it turned up and I'm impressed. Nice material, decent build, magnets plenty strong for keys, phone and a 500 ml bottle. Loses a star for the lead time.

Will it stick at your gym

Tap your machine.

If it's steel, it sticks. Pick a machine or the brand your gym uses.

Sticks
Full hold on a squat rack.Painted steel upright. This is what the magnet is built for.
SticksHolds, lighter loadNo hold

Stick it to bare or painted steel, not padding, plastic covers or glass. Still unsure? Try it at your gym. If it doesn't hold, send it back.

Fit check

Will your stuff fit?

Straight answers

What people ask before they buy.

From our inbox and reviews. No spin.

Will it really hold with everything inside?Yes. Bottle, phone, keys and wallet, on any steel rack.
A full bottle, phone, keys and wallet come to about 4 lb, well under what the magnet holds. Keep it on steel, not on rubber coated rails or padding, and it stays put.
Will the magnet mess with my phone or cards?No. Your phone and cards are safe.
The magnet sits in the back panel, away from the pockets. Chip and tap cards don't rely on the magnetic strip, and phones are built for much stronger MagSafe magnets.
Is it the same bag as in the photos?Yes. What you see is the V2 you receive.
Every photo on this page is the current production bag. If yours is different in any way, send us a photo and we replace it or refund it, your choice.
Is it worth it for a small bag?It pays for itself in saved hassle, session after session.
No more locker runs mid workout, no phone on the floor, no bottle rolling under the bench. Spread over a year of training it costs cents per session. And if it doesn't earn its place in 30 days, send it back.
How long does delivery take?Ships in 1 to 3 business days. Arrives in 8 to 14 days.
We ship to Canada, the US and the EU. Once your order leaves, delivery usually takes 8 to 14 days.
Is shipping free?Free on orders over $55 USD.
Add the bottle and your order ships free.
What if I don't like it?Send it back within 30 days for a full refund.
Any reason, no questions. Email us and we send the return label.
What if the magnet stops holding?We replace the bag. The magnet is covered for life.
If it ever loses its hold, send a photo and we ship you a new bag.
What if the strap, zip or handle fails?Covered for a year. We replace it.
Fabric, stitching, zips, straps and handles are covered for one year. Send a photo, we ship a new one. No arguing.
Still unsure? Talk to us.Use live chat during working hours, or email us any time.

A note from the founders

We built it because our phones kept ending up on the floor.

OptiiForce started in Toronto with one bag and a lot of gym time. Here is what we promise every lifter who trains with it.
