Sawyer SPF 30 Stay Put Sun Block Bonding Base - 4 fl oz lotion
Experience as the primary supplier of sunblock to the troops in the Gulf War taught taught Sawyer just how important it was to hold a sunblock in place even in extreme conditions. In research since then they were able to identify how the skin accepts, rejects, or processes sunblocks. From that knowledge they have developed revolutionary techniques for holding the formulas in place.
