Short version: Haven’t found another bag with the same blend of sharp looks and good features outside of a less versatile Tumi bag, but some quirks- most of the build materials are excellent, the recycled wax canvas holds up nicely and takes wear well- internal organization is pretty good - a little more admin style pockets on the divider would be and improvement. The roll up divide is not intuitive but works well- quick access pocket and bottle are sturdier than they look, but the pocket is on the small side and the horizontal bottle pocket feels less secure- biggest issue is the handles and strap. The material is too thin and almost abrasive to skin. The pads help but don’t make up for itWould buy again for a travel bag, less for a daily gym bag

I have both this bag and the Aion 40L backpack, and I like this duffel bag better. The split-folding design is better for organization, and eliminates the need for most packing cubes. It holds almost as much as the 40L, and it's more versatile - use it for the gym, 1-bag travel (with laptop), or pair it with a personal-size backpack for more gear-intensive trips. It's very light, so a cross-body carry is quite comfortable, as long as you're just trekking through the airport or to your hotel.The top pockets are a great idea - typical duffel side pockets get squished as the bag fills up. It has enough organization, not overkill, and putting most of it in the middle of the bag keeps a nice clean profile, while still allowing easy access.The only downside is the ... MoreI have both this bag and the Aion 40L backpack, and I like this duffel bag better.

If you need to stuff in ski-boots, this isn't your bag.Overall a very well-thought out design. And the Nutria color is awesome.

It is a great looking bag. I bought the so called nutria colour. It is simple but made with quality materials. Not much in terms of internal pockets but it works for me. Only defect: It says it accommodates a 16 in laptop. Yes, it does, but barely and this makes it awkward to close the bag and the laptop is not very protected. SoI will not use the laptop compartment for my MacBook 16. But the compartment is still a nice padded divider between the 2 sections ad can accommodate a smaller laptop or an iPad.

Purchased this in addition to the Thule Aion Spinner in hopes that it would make a nice personal item. The bag itself is beautiful, well-designed, and seemingly very durable. The little zippered pouch on top seems so handy! I'd previously used a duffle-style bag as my personal item in the past (was always sort of a tight squeeze, but we managed!). This guy's just too chonky when packed to even hope to squeeze by, not a fault of the bag - more on my blind optimism. The trolley strap holds well & the bag sits nicely atop the spinner and stays put (even as top heavy as it was). I'll be returning it as I can't rationalize keeping it on hand for the off chance I'll need only a duffle bag in the future. The nutria color is beautiful & I'm sad I won't get to see it age. ... MorePurchased this in addition to the Thule Aion Spinner in hopes that it would make a nice personal item.

Just ordered this and received it. I have not used this yet. I do like the functionality. The zippers seem strong. However, it really looks like a different material online than in-person. It’s very plastic and cheap looking in person compared to online and is more of a true black than a greyish black like pictured.
I bought this for a cross-country train ride. It is rugged, made with heavy-duty quality zippers all the way around and long-lasting durable material. This bag traveled crammed full from GA to CA, thru two train major stations and three trains. I ended up checking it when I flew back from CA to GA. This bag went thru baggage check with Delta in CA, changed planes in Utah, and finally ATL. Not a mark on it. This bag is amazing. Handles are well placed for portability, shoulder strap is well padded, and the various pockets are well distributed for the balance of personal belongings. Highly recommend. I wasn't crazy at first about the color, but now I'm glad I got this one and not black. Easy to spot.
The design of this duffel is phenomenal, with one exception: the water bottle pocket is on the top and the laptop/tablet sleeves are in the middle, so if your water bottle ever leaks, it does straight onto your electronics. I bought this as a daily commute bag to hold electronics, gym clothes, and yes, a water bottle. So it doesn’t work for me.However, if you don’t intend to put a water bottle in the top pocket, it’s an incredibly designed bag. The electronics sleeve in the middle provides extra protection. The dividers for the different sections are clever and the snaps to tuck them away work flawlessly. I’ve seen reviews suggesting the material of the waterproof divider is flimsy but it felt very sturdy and durable to me. I would heartily recommend this to ... MoreThe design of this duffel is phenomenal, with one exception: the water bottle pocket is on the top and the laptop/tablet sleeves are in the middle, so if your water bottle ever leaks, it does straight onto your electronics.

Like all the other bags in the Aion series, the bag is awesome. The quality of both craftsmanship and materials is outstanding, I particularly love the waxed material. The middle separation, that has a laptop and tablet sleeve to keep your electronics safely tucked away, also allows to separate wet or dirty items from everyday essentials. The handles on all side and the removable shoulder strap make it extremely flexible. The stretch pockets at the top are an original touch I have never found on any other duffel.Add to it the pass through panel that allows the bag to be secured to a rolling luggage and this is the perfect bag... or quite nearly so.Personally I would like to see a 50ltr version as this is a bit too small for my needs.If the size is right for you, ... MoreLike all the other bags in the Aion series, the bag is awesome.

Very light, functional and well thought out. Ease of a duffel but with organization including one side for dirty laundry, shoes or damp items. The center holds a lap top, iPad and tech cords. It opens flat so easy to access things. Haven’t traveled with it yet but I think it is going to be great.
