Fit is good, adds stability to the little brother pack.highly recommend
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.
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.
I ordered this form my G1 Little Brother and it works well! Super easy to install and remove plus the weight is very low.
Very supportive and extremely comfortable!
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.
Is it compatible with the little big top? Would I need to remove the plastic frame sheet or leave it installed?
Fits great and does exactly what it is supposed to.
The Endo G-type internal frame really improves the performance and comfort of my Transformer pack as a stand alone ruck for early season scouting.
Definitely a must have if you plan to use the Transformer without the F1 Mainframe.
Exactly what I I wanted and fast , fast delivery.
