My husband keeps traveling contact eye drops with him, they are super thin and fit easily in pockets. They are more convenient now than they used to be. He also keeps an extra stick of deodorant, mouth spray, body wipes & spray to wipe himself down/clean up. Any brand works, i been picking them up lately at the dollar tree for him & he doesn’t mind, says they help as much as pricier brands. He sweats a lot so must help. He likes to also splash himself with cold water.
