A COMMUNITY-DESIGNED PRODUCT
This product was designed with customers who gave input from idea to production. See the process here.
The Flex Travel Gym Bag comes in one size and holds a variety of items one uses for the gym. Some example:
When used as a travel bag, the water bottle pocket can hold headphones and gear pouches.
This is my second bag from them. My first messenger bag is over 10 years old and still going strong, the leather has aged beautifully. I bought this gym bag and used it for a trip to Yellowstone. The shoe compartment kept my muddy shoes completely separate from my wedding clothes, which were also in the bag.
Air travel was easy. The bag is small enough to fit in the overhead bin even when the bins were already full, and the flight attendant didn’t make me check it, even though I was also carrying a backpack and a carry‑on.
After the trip, I ended up buying their backpack as well. Great quality, great look, and a great buy.
This bag suits me to a tee for a weekend getaway. The quality is top-notch as with all Waterfield products.
As a yeti, I was concerned that the internal shoe bag wouldn’t be big enough to fit my size 15s. So I was 50/50 on whether or not I’d be able to keep it. GOOD NEWS: it fits my shoes with room to spare. I’d guess you could fit up to 17s? 18s? Hard to say, I just know that even greater yeti may be able to use this gorgeous bag, too.
The bag was definitely smaller than I was expecting it to be, and I've found I have to prioritize a bit what I bring with me to fit everything in. Picture in your mind a gym bag, and then shrink it by about half, and that's the size of the bag. The quality is high though and the design is quite thoughtful. I just wish it were bigger.
Although it is a little smaller than I had imagined it, it works extremely well for what I need it for! Mainly used as a gym bag, but I have used it as an overnight bag, and it has served me very well so far! As a frequent Waterfield Bag buyer, they continue to impress me!

“I was surprised to find out how small this bag is for being 25l, but what it lacks in size, it makes up for in small storage pockets.”
Designed with input from 1400+ fitness enthusiasts, this bag features exactly what gym goers need most. Those in-the-know will recognize details not found on most bags.
Designed to keep things organized and easy to access, the bag has pockets for storing bands, straps, rope, hand grips, wrist wraps, weight bar locks, etc. The water bottle pocket expands inward to fit large shaker bottles or two water bottles. A collapsible, ventilated shoe compartment separates shoes from clean clothes. And because we know how frustrating it can be to hunt for locks and keys, a dedicated tether for attaching them is included.
Whether you go to the gym once a week or every day, the Flex Travel Gym Bag ensures you'll always have everything you need for your best workout yet.
Customers indicated they sometimes carry personal items — phone, key, small notebook — with them on the floor. The EDC Pocket Organizer (sold separately) fits these essentials and fits perfectly in the deep interior pockets of your Flex Travel Gym Bag. For your post workout needs, the compact Travel Light Dopp Kit (sold separately) keeps toiletries separate and neatly organized.
You can store these complementary pouches in the Flex Travel Gym Bag so you'll always be prepared whenever you get to the gym.
The Flex Travel Gym Bag is also the right size for a weekender. The bright interior with the wide opening makes it easy to pack and unpack clothes, shoes, and accessories you'll need for a couple of days.
The water bottle pocket is transformed to hold headphones and travel gear, and the back pocket can be used for carrying an 11-inch iPad in its own protective sleeve. There's even a slot in the back for sliding it onto the handle of a carry-on luggage.
This gym bag was designed with the help of fitness enthusiasts and gym goers. They told us the features they'd like, what they carried, and how they'd use the bag. See the process here.
The Flex Travel Gym Bag organizes gym gear and enhances the locker room experience. It fits in most gym lockers, includes a hook for a vertical hang, and has a built-in key tether for attaching your lock and key. Sweaty clothes go in a removable drawstring bag and shoes go in their own separate compartment. The liner can be easily wiped dry.
Big bonus: this bag also doubles as a travel bag for weekend escapes.
We're proud to offer American-made gear built for the long haul. All our products are designed and made in our San Francisco workshop, where rent is high, labor expensive, and competition intense. We wouldn't go anywhere else.
