We combine chemical-free UPF 50 sun protection that won’t wash out, eco-friendly materials, moisture-wicking quick-dry performance, and soft, lightweight 4-way stretch fabric that’s shrink-resistant, antimicrobial, and odor-resistant. With smart pocket storage, reinforced Velcro for heavier items, and flat seams for comfort, style, and durability—these are designs you’ll actually want to wear.

Hand or machine wash cold with similar colors, hang to dry. We recommend if washing in the machine that an eco-friendly washing bag be used to help maintain the sleeve.

Yep! We offer hassle-free returns within 30 days—no stress, just sleeves.

To start a return, just email us at beyou@zunraysclothing.com with your order number and reason for return. We'll take care of the rest!

Once your sleeve is ordered we are on it! The sleeve will be mailed out within three business days after order is received. You will be notified when the sleeve has been shipped.

Think of your Zun Rays sleeve like your favorite pair of leggings—snug but never suffocating.

It’s not a compression sleeve, so you won’t feel squeezed. But it should hug your arm just enough to stay in place and keep your must-haves (like your lip balm, credit card, or lucky golf tee) right where you need them.

💡 Pro tip: The top band should feel secure but comfy—no digging, no slipping, just smooth support.

Our fabric? Oh yes, it's been put to the test. It’s soft, breathable, and built to last through long walks, long flights, and long brunches. You’ll forget you're even wearing it... except when you realize your essentials are exactly where you left them.

✨ The secret sauce? Use our custom size chart to get that just-right fit: snug, not loose… and definitely not tight.
