In addition to my bicycle billfolds I also do these hot/cold packs. We all getting older and not spring chicks anymore much like the bicycles we ride. So after those long hours in the saddle from the day before. You wake up the next day feeling like rigor mortise set in. Take one and toss it in the microwave for two minutes or so or in the freezer for a couple of hours and apply where needed.

Long neck/shoulder pack
Roughly 20"x6"

Large rectangular packs

Small rectangular packs

*The packs with the Campag material are $4 more because I get the material custom made and is quite a bit more pricey *
