Pacific Fly Fishers Online Fly Shop & Catalog

Considered by many to be the best repellent made, Ultrathon was made by 3M for the US Military and tested in the jungles of Central America. It repels mosquitos, ticks, chiggers, biting flies, and fleas and lasts up to 12 hours with one application due to an advanced controlled release technology. This stuff has saved the day on days when it seemed like the mosquitos were going to pick you up and fly away with you. Highly recommended. 2 fl. oz. bottle.
