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

Flex Gym Bag, a winner

Been through many gym bags. But never fell in love ‘til now!

The Flex Travel Gym Bag - The end of a long quest

For me, the new Flex Travel Gym Bag is the perfect gym bag. The size of my previous gym bag was not ideal. It was also too soft/flexible overall and only had smaller pockets in relatively unfavourable places. My new Waterfield Gym Bag, on the other hand, is perfect. It is shorter but slightly wider than my previous bag and has the ideal proportions for me. It also fits better in the gym locker. The canvas material is stiffer and the bag retains its shape better. The smaller pockets are perfectly positioned for me to store my iPhone, keys and gym access card. The inside pocket for the separate shoe compartment is also a perfect solution. I rarely need this function, so it's perfect that this inner pocket can be stowed away so that it doesn't get in the way. However, if you do need to transport dirty shoes, it is ready in a flash. If you also cycle to the gym, you should consider ordering an additional shoulder strap so that you can carry the bag over your shoulder and keep your hands free. I spent a long time searching in vain for my ideal gym bag. With the new Flex Travel Gym Bag from Waterfield, I finally found what I was looking for.

Gym bag

Awesome bag. Love every aspect. Would like a strap rather than just the handles but still works great.

“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

Name: Flex Travel Gym Bag
Brand: WaterField Designs
SKU: FGMDZZBNCAZZZZ
Price: 389.00 USD
Availability: InStock
Rating: 5.0 (10 reviews)

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.
