spec-ops brands ''the p.a.c.k.'' it is my favorite pack small,medium or large.i have used almost all of the big name pack/tactical nylon makers gear and while satisfied with all can not say enough about this pack. appr. 2500 cu. in.,molle to the max and very comfortable.at 125.00 no body can compete.its worth every penny imo.also look into Tactical Tailor, or Eagle Industries.all offer life time warranties i think.
