Spare comfort pack
I ordered the concealable cool vest with the comfort pack so I ordered a spare set of the comfort pack so I would always have them ready to keep me cool as I work in 100 to 110 degrees weather all day. They are just as advertised. They are ready to use in 30 minutes when put in ice water and they last 2 to 2 1/2 hours. would definitely recommend getting an extra set with the vest.
UPDATE: This review is for the Glacier Tek comfort pack, which was discontinued in July 2018. The new replacement pack set features the same materials and an updated design: horizontal cells that conform to your torso as you bend and stretch.
