At lululemon, we want you to have a fun, active, and safe summer, so without further ado allow us to introduce your skin to UPF Sheer Jersey! Our designers have created a new fabric called UPF Sheer Jersey thanks to the feedback of our hot climate athletes who wanted more sun protection in a light weight option. Most UPF fabrics are considered thick, but we've been able to keep ours very thin, lightweight, and made sure to give you the anti-stink properties you love. So get ready to move this summer!

why we made this
The Run:Sun Blocker LS was designed for running in the sun without worrying about UV (Ultraviolet) rays harming your skin. It is constructed of UPF Sheer Jersey and Circle Mesh.

Lightweight UPF sheer jersey provides sun coverage and wicks moisture with an excellent UPF rating. The UPF Sheer Jersey has been strategically placed in high-exposure areas, such as the forearms and chest, to give additional sun coverage where you need it most.


Made with circle mesh panels along the sidebody, with an anti-stink Chitosan finish, which provides extra breathability. Circle Mesh has excellent wicking and anti-stink capabilities, but does not offer UPF coverage (it has holes!). The top is also flat seamed for chafe resistance & comfort in your runs.

Body skimming fit so it won't cling as you get moving.

Hidden back pocket for lightweight belongings.

Thumbholes to keep your sleeves in place, and your arms fully protected from the sun's rays.

Here is a video from our Product Trainer with more information about UPF Sheer Jersey:
Although the Sun Blocker LS was not made to be a replacement for sunscreen, it was made to give you additional sun coverage where you need it most. So go have an active, fun and safe summer! Namaste.
