A chart can not
really tell you what hip belt size you need. If you are climbing Denali or
winter camping warm clothing will add several inches to your waist. Below
is a quick table of approximate sizes that seems to work pretty well with
all packs.
26" and less - XS
25" to 31" - Small
30" to 36" - Medium
35" to 42" - Large
40" to 46" - XL
