I have the smaller version of the two shown...

Would you like it? I guess that depends on what you want in a back pack and the purpose you want to use it for.

I use it for elk hunting where I don't want to carry a big load all day.

The small one measures 17" x 9" x 4" and lists cubic inches between 850-1050.

The large one measures 20" x 11" x 5" and lists cubic inches between 1250-1500.

Hope that helps.
