Can the 22L Backpack fit in the 45L Backpack?Updated a year ago

Thanks for asking! The 22L was not designed to fit within the 45L backpack, but there are a couple of ways it could work if you want to try. 

1) You can attach it on the outside of the pack using the accessory straps. 

2) Depending how light you pack out your 45L, you should be able to fit in on one side of the main compartment or squeeze it into the expansion pocket.
