Under Armour Gym Duffel Bag

Summary: For a branded gym duffel bag, the Undeniable 4.0 from Under Armour is great value. This practical bag is waterproof, east to clean and has just enough pockets and panels to keep all your gym equipment tidy. You can carry it using padded handles or use it as a shoulder bag. It is the size that impressed me the most. It’s hard to get that exactly right sizing, and Under Armour have obviously done their research. The Undeniable gym duffel is a quality bag, at a price point not far above those ‘knock-offs’ that seem to be everywhere these days.

Feedback is massively positive for these bags. You can see the thoughts of 1000’s of gym goers that tried these duffels over on this dedicated amazon.co.uk product page – check it out now!

Detailed Review of the Undeniable 4.0 Gym Duffel Bag from Under Armour

These gym duffels look compact, though they have a 41-litre capacity. This is plenty enough for most of us to hold everything for a gym trip. The size is 55cms across, 27 tall and 28cm deep. As you will see below, those 41 litres are spread between one main compartment, plus various pockets, and pouches. That is almost as much as you would fit in a typical hand luggage case for a flight.

Four colours are available. They are all darker / practical designs, no garish colours from Under Armour!

You can pick from black with metallic gold detail, black with black panels (and a white logo), black with a graphite grey front section or a dark blue one with a white logo. They all have a large U-A logo.

Quality Material

When you zoom in on the pictures on the amazon.co.uk product page, you will see a second logo. This says U-A Storm. This is the patented tech developed by Under Armour for the finish of their gym bags. This is designed to battle the elements and stay highly water resistant. There is no reference to sweat in the marketing pages… though I’m sure you can put two and two together!

Not only will this covering resist water, but it will also protect against scuffs and abrasions too.

Pockets and Straps for the Under Armour Gym Duffel

There is a big, curved lid on the top of these duffels. This makes the main compartment easy to access. You can store all your main kit in there, unzip and pull back the lid, and have access to everything all at once. There are dual zips, which you could lock together (no padlock is provided).

Add to this a zipped long pocket on the front, separate pocket for your shoes on the side and internal organiser pockets, and you have a versatile bag.

There are padded handles for carrying this bag, you also get an adjustable shoulder strap. Last (though not least), you get a plastic D-ring to attach things to.

Feedback: What Previous Buyers Said About the Under Armour Gym Bags

Positive feedback is overwhelming for this bag. I’ll start with the negatives to keep things balanced. One gripe was the fact that the shoulder strap is sewn on. People expected this to be detachable (my guess is that the added plastic D-ring caused the confusion). Needless to say, there was fury, there was angst, there were long, rambling rants… how dare they sew on the shoulder strap – my entire life is now ruined forever! (ok, it could be clearer, I’m sure you get the point!).

Most people loved these bags. For the low price, a branded bag with special materials and multiple pockets ticked the right boxes for almost everyone.

Make sure you read the latest feedback for yourself before you buy. If nothing else, it will give you insight into the average literacy levels (shockingly low) of the population.

Wrapping Up: Is the Undeniable 4.0 Gym Duffel Bag from Under Armour Right for You?

This bag is perfect for anyone that has suffered with a cheap ‘no name’ bag, only to see it fall apart after a few months. When the penny drops that quality is better value – you are ready for this Under Armour gym duffel.

It has Storm covering, multiple pockets, padded handles, and a strap (which is not removable). With a 41-litre capacity, you can store all your kit easily, with vented waterproof pockets at hand for your used gear.

For me, these bags are excellent value – check out the designs, any discounts, and the latest entertaining comments for yourself now, over on this dedicated amazon.co.uk product page!
