Frequently Asked Questions

What does UPF 50 mean?

UPF stands for Ultraviolet Protection Factor, the share of UV the fabric blocks. A UPF 50 rating blocks about 98 percent of UV rays. A long-sleeve UPF rash guard gives you more reliable coverage than sunscreen, which can wear off as you sweat or wipe out.

Should I choose a long-sleeve or short-sleeve rash guard?

Long-sleeve rash guards cover your arms and shoulders, so they're the better pick for full-day sessions and high-sun trips to places like Hawaii or Mexico. Short-sleeve cuts run cooler and feel less restrictive, which is what you want in tropical water or hot-weather swims. If you're not sure, long-sleeve styles give you more coverage across different conditions.
