How To Choose The Right Internal Frame Backpack?

Whether an internal frame backpack suits your requirement depends on whether you are going camping, trekking, or just heading to a neighboring city for a weekend trip. We tell you how to choose the right backpack in a few simple steps.

  1. Measure your body: Start measuring your torso from the topmost part of your neck and end near the hips. An extra small backpack is ideal if you have a torso length of up to 15 inches. You can choose a longer version if your torso is 20 inches or longer. Women should also choose backpacks with shoulder straps and belts that are better suited to their body shape.
  1. The gear you have to carry: If you are going camping for two to three nights, then a backpack should have 60l capacity, while a trip that lasts over five nights will need an 80l or larger backpack. Additionally, if you are camping or trekking in the winter, you will need a large internal frame backpack.
  1. Options to customize the backpack: A good internal frame backpack can be customized for fit you well and could minimize the strain on your shoulders. The ones with a custom fit are stable and remain in place even when hiking over uneven terrain.
  1. Number of compartments and pockets: Consider the number of compartments available within the backpack and its exterior. Go for one with more compartments for better and easy organization. A backpack with a main compartment that can be accessed from the top and sides with easy access to gear is a better pick.
  1. Rain cover: If you choose an internal frame backpack with a rain cover, then you can get good protection for your gear when it rains, and you do not have to spend extra to purchase one separately.
  1. Durable material: Picking a backpack that is made from tear and water-resistant fabric will ensure that it lasts longer. Also, check the quality of zippers, such as top quality YKK ones that are less likely to fail.
  1. Hydration bladder sleeve: Some backpacks come with a sleeve that is designed to store a hydration bladder and a port for it, and these are ideal for getting a quick drink on the go when trekking.
  1. Exterior attachment points: You will need attachment points on the backpack exterior to hang gear, tools, a sleeping bag, or poles, so ensure these are available.

As backpacks have a lot to carry in them, a normal one would cause sore shoulders and pain. In such case, internal frame backpacks come as a great help. You must purchase a backpack that can be customized to suit your requirements. Always check the number of compartments it offers and whether it comes with a rain cover. With optimum durability and comfort to be carried around, you are good to go for your next hike.
