This moisturizing, water-based lubricant feels just like a slick silicone lube and offers a similar long-lasting appeal. Latex safe, odor and fragrance free, System H2O offers a silky, smooth-feeling lubricant that never gets sticky or tacky and washes off easily in water. This is a great lube for people who love the silky feel of silicone but prefer a water-based lubricant.
