Coghlan's Tissue on the Go is a go-to when nature calls.  Fitting easily in a pocket or pack, this tissue features a pull-out dispenser that keeps the soft 2-ply tissue neat, clean and dry.  The rolls do not have a cardboard core which saves weight, waste, and allows it pack down smaller.

This two pack features two dispensers and two rolls of toilet paper.  Leave the dispenser at home and use a ziplock to save weight.
