I have purchased this before traveling which has allowed me to pack both lightly and also allow me to utilize it for flexibility. I used it both for urban and nature and it helps with a lot of space if you are running low. I even paired it with my osprey raptor which helps me pack light for hikes but also have extra room for longer days and important items.

Despite using it about a dozen times, I enjoy using it for those reasons. Though there's things I am very disappointed in. Boundary has always been recognized since day one for their quality and use of material and innovative solutions to looking minimal, functional and durable. Though i found it to be a minimal, and functional - I did not find this particular product to be durable despite the claims.

The EXM Port pack for me start to wear and tear despite this item being in the rain a handful of times (3-4 times), the clip that attaches the sides together opens up and doesnt lock properly at times, finding my bag falling to one side during hikes and cycling.

I would only recommend this if the durability is fixed. Otherwise, I do not see this as a long-term investment for the pack as it wears too quickly.

Bought last week, already used extensively. Perfect as a bag for shoes, attached under my Prima System bag.

Well made, looks great and fits perfectly to the Errant pack. Probably a bit expensive for what it is though.

Very useful bag for travels or when you need to carry some extra things.

It’s easily removable without having to open the bag.

The downside is that it needs the straps so you have to add that to the costs if you want to transport it linked to the backpack like in the photo.

Perfect material.

Recommend.

Great!! I would find a way to integrate 2-3 EXM Port 6 Liter for a single backpack in different colors. That would be amazing!
