Well I'm the guy who admitted on another thread to have carried a floor pump on a BOB trailer across the USA, but I'm a weight weenie when it comes to razors! The cheapest single blade BIC disposable is my choice. Weighs next to nothing, including a re-useable blade guard, 12 for $3 at Walmart! One razor lasts for 2 weeks of daily use at home. Shaving cream? = soap. Brush? = fingers. Environmental impact? Much less discarded plastic than one soda bottle.
