Review: The Airfare Super Saver Backpack! - I liked this backpack so much I decided to make a short video about it. Here is the backstory of how I found this pack and why I like it so much. Airlines now sell super cheap ‘Basic Economy’ fares. With this fare you are not allowed to carry-on a roller bag. And if you try to take a roller you pay the check bag fee plus a penalty of $25 at the gate. In my experience they will let you on at the gate with a backpack as a personal item that may be bigger than their personal item spec. This made me look for a backpack that expands to fit the stuff I normally put in my roller but also compresses so that I can use it as my computer day bag after I arrive at my destination. This pack is just perfect for this! In its compact form it is just a bit bigger than my normal computer bag with a nice sleeve for my computer. It has a fantastic expansion system (see the video) which allows me to pack everything that was in my roller. It has compression straps so that I can cinch it down to a size that will fit under my seat if necessary. It is super light and super durable. The materials are heavy duty and the workmanship is as good as the most expensive name brand packs. It has just the right number of external pockets (I hate having too many cuz I just lose stuff). For my needs the one complaint is it has too many cinch straps and an unnecessary waist strap. But I can see how those might come in handy for camping. The price is insanely great. I can’t believe they can manufacture and ship it for $27!!! It pays for itself twice on just one trip where I save $30 each way for checked bag fees. Bring on those super saver Basic Economy fares I’m in! :)
Review: Good quality, comfortable, and spacious - I bought this to use when riding my motorcycle. I needed a bag large enough to carry my lunch bag, 32 oz. water bottle and a change of clothes. This works great! I love the expandable feature (40-50L), the straps are comfortable, and the chest strap was a must. I also appreciate that the waist strap was not padded, as it tends to be too bulky when on the bike. The zipper construction is good, and there are ample smaller pockets and zippered sections for my phone, wallet, tablet, etc.

### ⭐⭐⭐⭐⭐ Versatile backpack
*by C***Y on April 12, 2023*

This is a great product at a competitive price. It is the right size at 40 liters to take on s plane as carry on luggage. Then it can be expanded to 50 liters with its zip around compartment. It has a chest strap and a waist strap making it ideal for walking on rough ground or hill climbing. It is lightweight and rugged at the same time. It has six clinch straps making a nice solid pack regardless of how full it is. Nicely padded with mesh material, it it good for the long day hike. I should have ordered this earlier as it was scheduled to arrive just in time for my planned trip. Then it arrived 15 hours later than promised so I had to delay my ground transport and then pack in a rush to make my plane. Mostly my fault but still a minor inconvenience. I am using the backpack in Germany and Ireland for this trip and it is ideal in every way.
