34L for The 46L....
The Exos34(M) is a well made(Little)backpack, afew more straps then I wanted but they can be tucked away. Very comfortable to wear, seem to lighten the load that I had put in it. Returning it for The 46(M). The 34(M) was just alittle to small for what I needed it for. The Jungle Green, very low profile. Very nice little backpack.
