The Perfect Weekender

This bag suits me to a tee for a weekend getaway. The quality is top-notch as with all Waterfield products.

Flex Travel Gym Bag

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.

High quality bag, though a bit small

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.

Great Bag

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!

My favorite and the perfect Waterfield bag of all

I am so happy with this bag. I’ve purchased several Waterfield bags over the last decade or more, and am always pleasantly surprised when each one goes above and beyond its marketing promise.

Once again I’ve found a high quality, good looking bag that is easy to carry and filled with utility.

The shoe compartment is my favorite part of the bag, keeps my size 11 gym shoes separated from all other clothing and content. The lock tether and pocket keeps my locker lock covered inside the bag so it doesn’t scratch my car when getting in and out as it did with my last bag. The dirty clothes bag was something I didn’t expect and is great for keeping soiled and clean clothes separate. This bag has a place for everything, my gym gloves, toiletries, gym clothing and a change of underwear.

I didn’t expect to like the carry handles as I normally use a strap, but I carry the bag using the handles over my shoulder and they stay put due to the construction, ingenious.

In short, this is my favorite bag thus far from Waterfield! J

“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.”

Design details

THE ULTIMATE GYM BAG


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. 

EXTRA ORGANIZATION  

 

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. 

BEYOND 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.

ENGAGING OUR COMMUNITY

 
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.
