My final pack decision was between SG and Exo as well. The Exo is unparalleled due to its organization, compartments, and little features along with better weather protection. I couldn’t get over buying an expensive pack AND THEN having to buy more small organization pouches to keep my items organized. With the Exo, minimal extra pouches are needed, unlike the other option which would require a lot.I recently bought a pack after lots of research and decided on the Exo 5500. The SG and Exo were the final two packs I was choosing from. After a call to exo and excellent customer service I placed the order and received it within a week. After a little time with it I really like the layout of the pack and would recommend it. Also Exo offers a 30 day return policy if you decide you don't like the pack or it doesn't fit you right. Pick any of the packs above and you will probably be happy with what you purchase.
