Alex D1 duffel bag

A bag for work out and travel

  • The past few years was not easy for all of us, and more than ever, working out became crucial for keeping positive mind and healthy body. So that when the time is right for travel again, we will be fully prepared for all challenges and opportunities. That's why designed Alex D1 duffle bag, a gym bag as well as a travel bag. 

 Loaded with unique features

  •  Unique ventilation system for working out.
  •  3 way carry for travel and short trip.
  • Only weights 1.2kg, minimal and durable.
  • The over all capacity of Alex D1 duffle bag is about 28L, perfect size for working out, short travel, weekend trip, etc.
  • Not too big, not too small, Alex D1 duffle is bigger than most common backpacks, and smaller than the biggest duffle bags in the market. Yet it has an unique smart way to store and separate different items. :) 
  • Alex D1 duffle bag uses premium ballistic nylon as main material, super tough and very light weighted, only around 1.0 to 1.2kg. And it can be folded very flat when not in use. 

"Sweat problem"

  • We all enjoy a good work out, it lifts up our mood, and brings us sense of achievements, but we all have to face the "sweat problem" 

Do you have a similar experience ?

1. Go to gym with a full bag of dry clothes.

2. Sweat a lot, and finish with everything damped by sweat.

3. Your gym bag doesn't have enough space for the pile of wet shirt and shorts.

4. Your wet clothes end up smell bad, due to lack of ventilation.

5. You wonder, wouldn't it be great to have a bag that has enough room for all damped items and keeps them ventilated?

Well, that's why we designed Alex D1 duffle bag.

Unique solution to a common problem

  •  Shared volume:  The bag has two main chambers, dry clothing chamber on top, and a side chamber, and the main volume of Alex D1 duffle bag is shared between these two chambers.  
  • When we reach the gym, the dry chamber is full and the side chamber is compressed. After the workout, the dry chamber is empty and will be compressed by the side vent chamber to make room for the wet clothes. So now you have more than enough space for all the damped items. 
  • Dry items can be loaded from the top main compartment of the bag. Very spacey and wide open. 
  • After the workout, the main compartment would be quite empty, and dry clothing become wet, which can be loaded from the side vent compartment of the bag against the mesh window for ventilation. 
  • Unlike other existing duffle bag, which usually have very limited capacity for wet items, the Alex D1 duffle bag vent compartment can be stretched into the whole capacity of the bag, thanks to the share space design.


Air flow is the key

  • Alex D1 duffle bag comes with huge dual mesh window on each side of the bag, and they are designed to allow better air flow, so that all the wet items can stay ventilated and not become sour. 
  • The two big mesh windows facing towards each other connecting the outside space, allowing the air to pass through the bag. 

Blower demo of the air flow 

  • In order to give a more vivid demo of how this ventilation system works, we took a blower to generate some air flow from one side of the mesh window, and this wind went right through the chamber, pushed down the feather outside the other mesh window.
  • The dual mesh windows of Alex D1 duffle bag can be opened for ventilation, or closed for more protection and privacy.  
  • You can control it with the zipper around the window. You can open the window very big, or quite small. Your choice. :)

Mesh window demo video

  • Fold inward the cap and zip down the side zippers to control the window cap. To close the window, just tear open the zipper, and close the zipper around the mesh window. Please see the demo video.

  • Having the wet items placed against the opened mesh window for better ventilation and keep the odor to the minimum.  
  • Other than the damped items, shoes should be kept ventilated as well, otherwise they will smell very bad. And obviously we can't place shoes together with other wet items, therefore Alex D1 duffle bag comes with a separated shoe compartment. 


  • When you don't need the shoe compartment it can be folded and tied down on the side. Although it looks quite flat and small when folded away, the shoe compartment on Alex D1 duffle bag is actually quite big.  
  • And when in use, you can expand the shoe compartment and place the shoes inside then tie it down, separated from other items. The Shoe compartment is quite big to fit most size of shoes. The shoes in the image is EUR size 45 or US size 11.
Alex D1 duffle bag shoe compartment is quite big.
