5 best internal frame backpacks

Internal frame backpacks are a type of backpack designed with an internal support structure to provide stability and weight distribution. These backpacks are commonly used in activities such as hiking, backpacking, and outdoor recreation. They are part of the broader category of backpacks and bags designed for camping and hiking purposes.

Here are key features and aspects associated with internal frame backpacks:

  1. Internal Frame Design: Unlike external frame backpacks, which have a visible frame on the outside, internal frame backpacks have a concealed frame within the backpack. This internal frame is typically made of lightweight materials such as aluminum or carbon fiber.

  2. Stability and Balance: The internal frame serves the purpose of providing stability and balance to the backpack. It helps distribute the weight of the load more evenly across the wearer's back, enhancing comfort during extended periods of wear.

  3. Close-to-Body Fit: Internal frame backpacks are designed to sit close to the wearer's body. This design minimizes the chance of the backpack getting caught on branches or rocks while hiking, making it suitable for off-trail and rough terrain adventures.

  4. Adjustable Straps and Belts: These backpacks often come with adjustable shoulder straps, hip belts, and chest straps. The adjustability allows users to customize the fit for their body, improving comfort and reducing strain.

  5. Capacity Options: Internal frame backpacks come in various capacities to suit different needs, from day hikes to extended backpacking trips. The capacity is measured in liters and indicates the volume of the main compartment and additional pockets.

  6. Ventilation: Some internal frame backpacks are designed with features to enhance ventilation, reducing sweating and discomfort during prolonged use. This is particularly beneficial in warm or humid conditions.

  7. Multiple Compartments: Internal frame backpacks typically have multiple compartments and pockets, allowing users to organize and access their gear more efficiently.

  8. Durability: High-quality materials and construction contribute to the durability of internal frame backpacks. This is essential for withstanding the rigors of outdoor activities and varying weather conditions.

When selecting an internal frame backpack for hiking or backpacking, it's important to consider factors such as the intended use, duration of trips, and personal preferences for features and fit.Properly fitting and well-designed internal frame backpacks contribute significantly to the overall comfort and enjoyment of outdoor adventures.

User questions & answers

Question: How well does this pack work for women? I'm 5'4" and worried this may be too big. I do need a ~60L pack
Answer: With a torso range of 14.5-18.5 in (37-47 cm) the Redwing 44 is very much a unisex pack. The best fit will be within the torso range. To measure your torso:Have a friend measure your back. Stand with your back to them and your hands on your hips like you are scolding someone. Your thumbs will point to a stop on your lower spine. Start from this point and measure up to the C-7 vertebrae, which is the one that sticks out of the back of your neck when you touch your chin to your chest. The measurement between these 2 points is your torso length.
Question: I'm a big ol' fat guy, I have a waist of about 60 to 62 inches. Will the waist belt on this pack be able to buckle for me
Answer: It fits my 14 x 10 MacBook comfortably with room to spare. What size laptop do you have? I can double check for you.
Question: Good pack for 2-3 days hike? First time for backpacking, done a lot of hiking, and need a good starter pack for a 3 day hike
Answer: Yes, same height. Pictures at https://www.amazon.com/gp/customer-reviews/RYHUV661ZFSAO/ref=cm_cr_getr_d_rvw_ttl?ie=UTF8&ASIN=B014JQ9H9K
Question: x box
Answer: Yes, it can reach 22 inches. Full review with pictures at the airport here: https://www.amazon.com/gp/customer-reviews/RYHUV661ZFSAO/ref=cm_cr_getr_d_rvw_ttl?ie=UTF8&ASIN=B014JQ9H9K

User questions & answers

Question: How to repack
Answer: There are no "straps" per say on the bottom. There are however two diffrent sized loops on the bottom that, from my understanding help keep treking poles in place. I would consider strapping a tent to one of 4 places on the pack. 2 being on either side of the pack where you can store water bottles. On the top or on the senter of the pack where you can adjust the compression straps.
Question: Hi. will it fit a macbook pro 15” and protect it from rainwater walk
Answer: Yes it is padded very nicely. I just used it to hike the presidential trail for 3 days and it was very comfortable.
Question: Has anyone used this pack as a carry on personal item--that is, to fit under the seat
Answer: This is my go to carry on bag. No issues on multiple flights.
Question: Would this be big enough for day outings with two kids and two adults? Like large enough to hold water bottles and maybe lunch and a towel or two
Answer: Yes, It does have a "laptop sleeve" on the inside of the main compartment which can hold a bladder where the hose can be fed out of the top of the bag and hooked to an attachment on the front right shoulder strap.
