You would choose the Sawyer Products Tick Repellent, the runner-up, over REPEL if you need long-term protection for your clothing and gear rather than direct application to your skin. The Sawyer repellent bonds to fabric and lasts up to six weeks or through six washings, making it ideal for camping trips. While REPEL can be used on both skin and clothing, Sawyer is particularly effective for those who want to keep their family tick-free while camping outdoors.
