The QuadLock Magnet Array™
Four magnets.
Spread across the back panel, so nothing hangs on a single point.
- 01
Find steel.
Racks, cable towers and plate-loaded frames are steel. Thick powder coat weakens the hold, and aluminum won’t hold it at all.

Press the back flat.
The back panel goes flat against the frame and locks. Your bottle and phone face out, within reach.

Highly Functional Gym Essential
I've used this bag for a few weeks, and it's already become a crucial part of my gym routine. The magnet is strong and holds up even with a full water bottle. The bag itself is spacious enough for my keys, phone, and earbuds without feeling bulky. I love the minimal design. It looks clean and professional. Already had 3 buddy's buy one after they saw mine.

Holds the Weight and Sticks Well
Delivery on time. Highly recommended, spacious, carries the weight of water and other items well that I took to the gym. It adheres very well to surfaces with its magnets.

Half the Price of the Brand Name
This bag is great considering the price for the brand name is double. It holds my full 30oz cup without sliding down. Magnets are strong. I love this bag for home and gym machines.

One of the Best Purchases I've Made
One of the best purchases I've made. I don't even like having a cell phone in my pocket, but I was very satisfied with this product. The material is high quality and the magnets work well. My bottle is 700ml.

Sturdy and Full of Pockets
Perfect. The material is sturdy and the bag is filled with various pockets. It's not very heavy, ideal for weightlifting.

I Turned It Into a Bike Bag
I attached a strap to the magnetic part of the bag and converted it into a bike bag. I love the sturdy and waterproof zipper.

Game Changer
This makes my workouts feel way more convenient. Strong hold and great quality. I move between machines and just slap it on. No more walking back to my bag.

No More Dirty Floors
Finally don't have to place my bottle on the ground. There always seems to be hair that sticks to the bottom of my bottles and it is gross. This keeps everything clean and off the floor.

Stays Put
Even with a full bottle, it doesn't slide or fall. I was skeptical about the magnets but they're seriously strong. My Yeti 26oz fits perfectly and holds on cable machines, squat racks, everything.

Worth Every Penny
The bag is amazing and so convenient. Whether I'm using it at the gym or on the course, it comes in clutch. I was hesitant at the price but after using it daily for a month, I'd pay double.

Perfect Gift for Gym People
Purchased this as a Valentine's present for my husband. He loves it so much. He said it is really useful and makes his time at the gym so much easier. He was flinging it at all the metal sides with pure glee.

Great Product, Wish the Strap Was Longer
Magnet is fantastic, holds everything solid. My only gripe is the shoulder strap could be a couple inches longer for carrying between the car and the gym. Once it's on the machine though? Perfect.

Solid 4 Stars, Slightly Smaller Than Expected
Works exactly as advertised. Magnet is strong, holds my phone and keys no problem. My only note: it's a bit more compact than the photos suggest. My 40oz Stanley doesn't fit, but my 26oz Owala does perfectly.

Good Concept, Didn't Fit My Bottle
The magnet works as advertised. Strong hold, no sliding. But my 40oz Hydro Flask doesn't fit. If they listed exact dimensions more clearly I would've known beforehand. Works great for my smaller bottle though.

Common questions
Before you
Straight answers, including the ones that cost us a sale.
Will the magnets hold a full water bottle?
On steel, yes. The QuadLock Magnet Array spreads the hold across 4 neodymium magnets instead of one, so a full bottle, phone and keys stay put on racks, cable towers and plate-loaded frames.
Will my bottle fit?
Bottles up to about 1 liter fit, including the 26oz to 32oz sizes most lifters carry. 40oz bottles like the Stanley and Hydro Flask don’t. Use the fit check above.
Will it work at my gym?
It locks to steel. Most racks, cable machines and plate-loaded frames are steel. Thick powder coat weakens the hold, and aluminum or plastic frames won’t hold it at all. If one machine won’t take it, the nearest steel upright almost always will.
Will the magnets damage my phone or cards?
Phones use solid-state storage that magnets don’t affect, and iPhones since the iPhone 12 have magnets built in for MagSafe. Chip and tap payments don’t use the magnetic stripe, but keep any card with a stripe in the front pocket, away from the back panel.
How is this different from the $15 ones on Amazon?
Four magnets instead of one, a reinforced build, and honest sizing. At $39.99 it sits between the knockoffs and the $60 to $100 brand names.
My gym has lockers. Why do I need this?
Lockers solve storage between workouts. The Carry solves access during one: your phone for tracking and music, your water between sets, your keys and earbuds, all on the machine with you.
What comes with it?
The Carry and its crossbody strap. You also get The Session Playbook e-book free, with the download link in your order confirmation email.
How long does shipping take?
It’s made to order and shipped direct. It ships in 1 to 2 days and arrives in 8 to 15 days. Standard shipping is free on every order.
What’s the return policy?
30 days. Use it through real sessions. If it doesn’t hold, doesn’t fit your stuff, or doesn’t make training smoother, send it back for a full refund. Digital products, like The Session Playbook, are final sale.
Day guarantee
Put it through
Use it on every machine for 30 days. If it doesn’t hold, doesn’t fit your stuff, or doesn’t make training smoother, send it back for a full refund.
