When the sun threatens to swallow us with sweltering heat, we fight back with the Backcountry Destination 1 / 4 - Zip Top. Designed with hiking, fishing, and travel in mind, this 1 / 4 - zip top boasts a peached polyester blend fabric that is soft next to skin, moisture - wicking, and full of stretch for movement. This fabric also offers a Upf 50 + rating that we love during hot summer adventures.
