A lot of backpackers know that internal frame backpacks have many advantages over external frame backpacks. Before you go out to get one there are some things you might want to consider.
One of the first thing to consider is the type of loading you want. You can either choose a top loader or a panel loader. In a top loader pack, the only way to load the main compartment is through the top.
This type of internal frame backpack is generally lighter than panel loaders because they use less materials, less zippers and less zipper flaps. You can cram in a lot of gear without having to worry about zipper failures.
Panel loaders are great if you want to have access to all the different parts of your pack through zippers. You can have zippers near the top, the side and the lower part of the pack but they're not limited to these areas. This type of internal frame pack can be very convenient.
You could consider the type of top lid as well. Most packs these days come with what is called a floating top lid, which means it can be adjusted up or down depending on the size of your load. Sometimes you can even totally detach the top lid and if it comes with additional straps, you can use it for a side hike or a day hike from camp. A fixed top lid is great for quickly storing your jacket underneath. It can also be used to keep something rigid like tent poles or sleeping pads.
Another thing to consider is the back panel area. The traditional foam back panel has a lot of contact with your back and makes the pack tight and snug which is great if you do a lot of dynamic movement like scrambling or going off trail.
If you are primarily a trail hiker, you might want to consider a trampoline style back panel. If you look at this type of back panel, you will notice that contact with the back is made with the frame on the side and a mesh panel is suspended in the middle. Here there is minimal contact between the back panel and your back.
The advantage of using this type of back panel is that you have a lot of ventilation on your back. This is especially great on hot days or if your back tends to get hot.
The next thing to consider is whether you want a fixed or an adjustable type of suspension system. If you know your torso length, a fixed system is great because it gives you maximum contact with the back.
If you go for the adjustable torso length system you give up a little bit of stability. In some packs you can even adjust the torso width. Some are easier to adjust than other so you might want to consider this as well.
Lastly, you can also consider whether you want an alpine style pack or a trail oriented pack. An alpine style pack has a lot of attachments, loops and buckles for your ice axes, skis, etc. The shape is also streamlined and it doesn't impede your movement so much.
The trail oriented pack is more about comfort and carrying weight effectively. There will be a lot of luxury features like pockets everywhere, different access points, water bottle pockets, well padded hip belts and shoulder straps.
