Backpack Review: Osprey Men’s Flapjack

I’m a big fan of Osprey backpacks. I only own 2, the Flapjack and the Viper 9. I really see no need to ever own another because between the 2 they do everything I need. I use the Flapjack for an all purpose backpack. The Viper 9 is my hydration pack, a great lightweight day pack.

Unless I started doing some serious long distance hiking/camping and needed a bigger pack, these 2 cover all the bases for me. If I decide I need something bigger, I would probably get the Atmos or the Aether. Both are top of the line, awesome backpacks just too much for me this point in my life.

They are made REALLY well and built to last. On top of the great quality, they have an awesome lifetime warranty. This is from the Osprey website:

All Mighty GuaranteeOsprey will repair any damage or defect for any reason free of charge – whether it was purchased in 1974 or yesterday.

You really can’t beat that and it tells you how confident they are in their product line. I love it when companies have lifetime warranties. I will pay a premium for that extra piece of mind, and I think many people feel the same way. Ok, on to the review…

What can you use this backpack for?

This is what I consider an all purpose backpack. It is good for just about anything you want to use it for. It may not be ideal for some things, but it always gets the job done.

No zipper for the main compartment, will stuff fall out?

I have never had this problem. Once it is buckled, stuff stays in place pretty good and there really isn’t anyway stuff could fall out even if you were shaking it upside down. The buckle makes it much easier to get in and out of in my opinion.

What size laptop can fit into it?

I keep my 13 in Macbook Air in mine and it slides in and out easily and doesn’t take up much room at all. As for what size it can hold, when I was doing my research before purchasing, several users reported being able to fit 17 inch laptops into this bag.

I don’t think many people have laptops of that size these days, but if you are one of them then you should be fine.

How is it for hiking?

I have taken it on many hikes. I took this bag to Hawaii last year and did some pretty good hiking with it. It did great, it’s a little bit bulky for long distances and you should be careful not to overpack it. It’s easy to keep throwing stuff in because you have so much room.

It doesn’t have the mesh side pockets that are good for water bottles, but it does have a side zipper pouch that I use for my water bottle. It’s not ideal because I have to stop and unzip it to get the water out, but it works. I am not 100% sure, but this pack may be compatible with a hydraulics reservoir from Osprey.

Weekend trips, is it big enough?

Absolutely yes, for me at least. I pack light, roll my clothes, and am able to fit 2 changes of clothes and toiletries no problem. You can also try out these packing cubes to help optimize your packing and get as much in there as possible.

Any longer than 2-3 days and you will most likely need something bigger, unless you are going to wash clothes not change clothes everyday.
