The AGIF Endo Frame is a great addition to many of our daypacks. Most of our smaller packs have classic internal small-pack frames called framesheets. These plastic sheets are well suited to their purpose, but sometimes our customers will want more structure. The Endo is the answer to this need; when inserted into the main load area of a pack, it nestles into the back corner, placing it alongside the main frame panel. Once there, the pack is transformed into a much more structured pack, with vertical and lateral rigidity. The great thing about this concept is that it adds very little weight to the pack, you can't feel any difference in comfort when the pack is on your back, and there is no noise associated with the frame.

The Endo has a subtle contour designed to enhance the lumbar support of our packs, and to follow the natural arc of the wearer's mid-upper back.

Endo Internal Frame

Purchased for my son's Big Brother pack, stiffens the pack substantially and is very lightweight. He is current active army and is using on his rucks, loves it!


I added this to my little brother pack and it made a big difference. It was tight putting it into the scabbard tunnel.

Really makes a difference.

I purchased this for my little brother bag that is part of my war hammer bag. It has made a huge difference. Makes it rigid enough to stand up. Lightweight yet sturdy.

Cant use but good product

I misread the question and answers regarding the product and after receiving the frame found out it didnt fit my switchback pack. Totally my fault. However, I used it in another (cheap) pack successfully and it seems to work well. It is a nice light weight addition to provide some rigidity to a pack without a frame.

Solid fit

I’m my opinion the bag can work fine without it - but I did want something with a bit more stability. Some might find the lack of structure in the lil’ brother a design flaw.

Anyway, this is a cheap, light, and effective solution to resolving the structure issue.

Loved the lil’ brother before. Love it even more now.

Excellent quality

I ordered this form my G1 Little Brother and it works well! Super easy to install and remove plus the weight is very low.

Excellent Frame

Very supportive and extremely comfortable!

Lightweight option for a ridged pack frame

There is a nice, tight fit and it certainly does add some support for a heavier load. The shape works best with the belt. It is a must if you wish to use is without the F1 mainframe and can be left in even when the pack is attached to the frame.

Little Big Top

Is it compatible with the little big top? Would I need to remove the plastic frame sheet or leave it installed?
