Too BIG or just right? Aer Day Sling 3 Max REVIEW

Following the successful Aer Day Sling 3, we now have the Aer Day Sling 3 Max, a full 6L sling bag for your EDC travel carry items. This review covers whether or not it's too big for a daily carry or best for travel. Like all Aer products, it comes in the XPAC material in black.

When you are not strapping something onto your back, a sling pack is the proper snack. In this review, we will be looking at the Aer Day Sling 3 Max sling pack for packing and carrying. I used this one on a recent international trip, but was it too big or just right?

The Aer Day Sling 3 Max is something you would take with you when you are going into the city or when traveling. It is fairly large in what it provides. I got it in the heather gray color, and I have got the larger version of the Day Sling 3, the Max, which is a newer release from Aer. There is also an X-Pac version that all Aer products have, which is a waterproof four-layer laminate that looks and feels like sail cloth and only comes in black. 

The exterior is gusseted in a very attractive way, the bottom allows you to stand up, sit upright, and makes access to the contents much easier once you get in from the top. It allows you to utilize the six-liter space of this particular bag to its full capacity. The front, on the other hand, has a protected zipper pocket that is outward facing your body so that you would carry it close to you. 

On the back, we have a protected zipper pocket that is flat for valuables usage, it can be sued for things that you want to keep close to your body such as passport, phone, et cetera. We also have the key strap with metal hardware which is more durable and easy to use, a rubber pole that I quite like, and the easily adjustable shoulder strap. Still, what I really like is Aer’s Fidlock magnetic system. 

The front has got a pocket with a YKK AquaGuard  #10 zippers that are waterproof, which I am not quite sure why. However, this  #10 AquaGuard is only on the front and nowhere else. That is one of the reasons why we have two loops that make it convenient to hold onto while pulling the zipper close. Waterproof zippers are not easy to open and close, therefore, being able to have something where you can hold on both sides to open and close the zipper is quite nice. 

The rear exterior pocket is where I would keep my travel documents, phone, and things I would rather keep close to my body, and that is where I would rather want to have that waterproof zipper for protection. We also have a loop hanger that you can use when you take off the pack, for example at a restaurant, you can hang it on something right next to you, which provides a nice little convenience. It also has an alternate carry method, the handle makes grabbing it very convenient and I like how it is offset to the back, not on the top, which makes it very easy to use. This is also a common element with the new Flight Pack 3 series handles. 

The interior of the pack has got kind of a Dump-O-Rama environment in the middle, meaning that you can just place whatever you want in the main compartment. All your larger items can be placed there, whether it is a jacket, an umbrella, a water bottle, and so forth. The interior has got four elastic pockets, a couple on each side. These pockets can be used for cords, chargers, earbuds, et cetera. They are larger than normal and do not bungee at the top, but have enough of a closure given that if you toss items they hopefully do not fall out. But if you are always keeping the pack in the upright position, the content should be fine. We also have one zipper pouch that is quite convenient for it is very large and goes the full length of the back. I like that we have something this large to be able to accommodate many smaller items. In my opinion, there always has to be a smaller zip pouch area where you can put smaller items to keep them compact, that way they will stay in place and not fall around. Then we have got a larger pocket that is suitable for up to an 11-inch tablet, an iPad, or whatever you might want to carry. It measures 12 x 9 x 3.5 inches empty and weighs one pound. Overall it is larger than just a normal sling, but if you carry more items, which there is nothing wrong with, then this pack does hit the mark.

It is designed in the United States and made in China from a 1680D Cordura, which is very strong, very durable, and can take a lot of abuse. It is bulk but I prefer it this way. As mentioned, it uses high-quality YKK zippers and has reinforcement in all the areas that you would expect. The right stress points ensure that this will last for several years. It is reasonably priced at $95, I do not think it is easy getting something as large and well-made for that price point. 

Yet, I wish these mesh pockets had some kind of elastic closure, a little bit more on both sides to keep items from getting out. The pen loop that comes with is part of the Aer logo, so if you want to put something in there, you can and it provides a nice touch, although, having a pass-through loop between the pockets would have been nice and that is very common in a lot of other slings. 

The flexibility it provides for travel makes this perfect for me, but as an around-the-town sling, it is a bit too big for me.

The final score of the Aer Day Sling 3 Max sling pack is five for quality, three for each the price and features, and four for each the usability and perception. This is an excellent little sling pouch that gets a final score of 4 out of 5.
