I put mine on diet- it weighs 2.7 oz, the only thing that varies for trips is the number of "meds"
roll of gauze, small curved tip irrigator, 2 4x4.5 tegaderm bandages, pack of 10 1/4 x4 steri-strips, two triple antibiotic creams, 3 2g Celox (hemostatic agent), 2' of Leukotape (wrapped around a section of a straw), 2 vials of tincture of benzoin, "meds"- ibuprofen, tylonel, bendadryl, imodium
part of my repair kit also does double duty in the first aid dept- single use crazy glue, needle, safety pins and duct tape
everything goes into a aloksak
my swiss army classic (0.9 oz) adds tweezers, scissors
pretty good discussion here:
