In plain English
An external-frame backpack has its skeleton on the outside. Picture a lightweight metal ladder that sits on your back, with the bag strapped onto it and a padded belt at the bottom that rests on your hips.
Because the ladder holds the bag a little away from your body, air can flow across your back, so you sweat less. The open frame is also handy for tying on odd-shaped things that would never fit neatly inside a bag, which is why hunters and people hauling camp gear still like them.
The trade-off is balance. With the load sitting farther back, it can sway when you twist, climb over logs or walk along uneven ground. Think of carrying a tall stack of boxes: it is easy on a flat floor and wobbly on stairs.

What should you look for in an external-frame backpack?
Look for a frame built from welded or riveted aluminum tubing, a hipbelt that attaches at the base of the frame rather than the pack bag, and enough external lash points to secure oddly shaped loads. These are the features that make an external frame worth choosing over the now-more-common internal frame.
Because external-frame packs are a smaller category today, model selection is narrower than for internal-frame packs. ALPS Mountaineering still manufactures traditional external-frame packs, and its designs follow the same basic aluminum-tube-and-pack-bag layout that's defined the category since the 1950s.
Aluminum tube frame vs hybrid designs
A traditional external frame uses a full aluminum tube ladder frame with the pack bag suspended from it by clevis pins or clips, keeping the bag and frame as separate, serviceable parts. Some hunting- and expedition-focused packs use a hybrid approach — a partially exposed or removable rigid frame combined with a closer-fitting pack body — aiming for external-frame load stability with more of an internal frame's balance on uneven ground.
- Traditional tube frames maximize ventilation and load-hauling stability for heavy, irregular gear
- Hybrid frame packs trade some ventilation for better off-trail balance
- Both designs keep the hipbelt attachment at the frame rather than the soft pack body, which is the core mechanical advantage of any external-style frame
Who should choose an external-frame pack?
Hunters hauling game meat, campers moving heavy or bulky irregular gear, and hikers who stick to maintained trails while carrying loads that don't pack down into a neat, evenly balanced shape are the best fit for an external-frame pack. The rigid frame holds its shape under an odd load in a way a soft internal-frame pack body can't match, and the gap between frame and back keeps hikers cooler on hot, low-elevation trails.
The trade-offs are real: external frames are bulkier, heavier empty, less stable on technical or off-trail terrain, and more prone to snagging on branches in tight brush. Hikers who spend most of their time scrambling, route-finding off-trail, or backpacking with a well-packed, evenly distributed load are usually better served by an internal-frame pack instead.
What features matter most on an external-frame pack?
Beyond the frame itself, the features that matter most are the number and placement of external lash points, how the hipbelt attaches to the frame's lower bar, and whether the pack bag detaches from the frame for cleaning or repair. Multiple lash points across the frame's width let a hiker distribute an irregular load — like a game quarter or a bundle of gear — evenly across the structure rather than concentrating weight on one strap.
A hipbelt bolted or clipped directly to the frame, rather than sewn only into the pack bag's fabric, transfers load more directly and holds up better under repeated heavy use. A pack bag that unclips or unlaces from the frame is easier to hose off after a muddy or bloody trip and easier to repair or replace independently of the frame itself, extending the working life of the whole pack.
How does empty weight compare to an internal-frame pack?
External-frame packs typically weigh more empty than comparable internal-frame packs, since a full aluminum tube frame plus a separately hung pack bag adds material that an internal-frame pack's embedded stays and frame sheet don't need. That weight penalty is a reasonable trade for hikers who need the frame's rigidity and airflow, but it works against anyone trying to keep total pack weight down for long-distance or fast-and-light trips.

Why the air gap and the load-hauling platform come as a package
REI describes external-frame packs as using visible, usually aluminum, frames that suit heavy, irregular loads and ventilate well.1 The ventilation comes from the same feature that shapes the carry: the frame holds the bag off the back. Load-carriage research points out the cost of that. Keeping the load's center of mass as close as possible to the body's center of mass gives the lowest energy cost,2 and a backpack shifts the body's center of mass backward, which people offset by leaning the trunk forward.3
The Army's foot-march manual puts a number on placement: packing heavier items higher and closer to the body can cut marching energy cost by as much as 25% compared with low placement away from the body.4 On an external frame, that means lashing the heaviest part of a load high and tight against the frame rather than hanging it off the back or bottom. Knapik's review adds a nuance: low or mid-back placement may suit uneven terrain, while high placement may be best on even ground,2 which fits the page's advice that external frames shine on maintained trails.
Heavy loads: what the evidence says about limits
External frames are usually bought for heavy loads, so it helps to know what the numbers do and don't say. The common advice to carry no more than 20% of body weight is a hiking-community rule of thumb without a primary source. Deuter, a manufacturer, says people can carry a maximum of 20 to 25%,5 while a 2022 review suggests adult loads should generally not exceed 40% of body mass.3 US Army doctrine sets an ideal of about 30% for a fighting load and 45% for an approach march,4 and a study of Appalachian Trail hikers found they actually carried 25% (men) and 27.9% (women) of body weight.6
Every extra kilogram costs something. One lab study found walking energy rose roughly linearly by about 7.6 watts per extra kilogram,7 and prolonged heavy carrying is linked to blisters, stress fractures, back strains, rucksack palsy and knee pain.2 A frame that can carry a heavy load does not make that load light, so plan meat hauls and gear shuttles in shorter stages where possible.
Checking the history on the page
The page says the aluminum-tube-and-bag layout has defined the category since the 1950s. Kelty's own history supports that timeline: the company was founded in 1952, and Kelty credits Dick Kelty with using aluminum frames, padded shoulder straps and waist belts.8 That is the brand's account, and the research for this site did not find a neutral source naming a single inventor.
The page's claim that hikers shifted to internal frames in the 1970s and 1980s, and its note on which companies still make external frames, were not verified by the sources behind this page, so treat those as general background. One dated marker from the period is Deuter's statement that it introduced its suspended-mesh Aircomfort back system in 1984,9 an early attempt to give a body-hugging pack some of an external frame's airflow.
Frequently Asked Questions
Why are external-frame backpacks less common now?
Hikers shifted toward internal-frame packs starting in the 1970s and 1980s because their narrow, body-hugging profile balances better on off-trail and technical terrain. External frames remain in production but now serve a smaller, more specialized share of the market, mainly for heavy load-hauling.
Are external-frame packs good for hunting?
Yes, for hauling out game meat or other heavy, irregularly shaped loads, an external frame's rigid platform holds its shape better than a soft internal-frame pack body. That's why traditional external frames and related load-hauling frame packs remain popular in backcountry hunting.
