Spacefish Army Mens Hammerhead Hibiscus Zip Rashguard

Quick answer: The Spacefish Army Hammerhead Hibiscus is a men's full-zip rash guard printed with bold tribal hammerhead sharks swirling through bright jungle greens and blues. It's recycled polyester and spandex with SPF50 sun protection, a plastic zipper made for salt water, a high collar and extended sleeves with thumbholes.

Straight talk on fit

Spacefish Army's men's sizes are cut on the trim side. Its 3X is listed at a 47-inch chest and 40-inch waist, so measure yourself against the chart below before you order. If you need more room, our extended-size collection has tops that go further. Note that the source lists XS, SM, MD, LG, 2XL and 3XL for this print, with no XL shown.

Why the details matter

The full zipper is the big one. A front zip makes a fitted rash guard much easier to get on and off, especially when it's wet, and the plastic won't rust or lock up with salt. You can also wear it open as a light jacket. The high collar helps stop neck chafing from a wetsuit or BCD, and the thumbholes help your arms slide through a wetsuit sleeve while covering the backs of your hands from the sun.
