The sun is out and you have three more hours of trail left. You don't want to reapply sunscreen. You don't want to overheat. You want your arms covered and your temperature down.
Boundless Bleed arm sleeves are built for exactly that moment — a Lycra sublimation sleeve that covers from wrist to upper arm, blocks UV rays, wicks moisture, and dries fast enough that you forget you're wearing them. The all-over print means they look intentional, not medical. At $13 a pair, they're the easiest upgrade to any outdoor kit.
What competitors miss: Most UV arm sleeves are plain white or a single color — functional but forgettable. Boundless Bleed uses sublimation printing on Lycra so the design wraps the entire sleeve with no seam breaks, giving you sun protection that actually looks like it belongs in a maximalist outdoor or streetwear kit. The 95% polyester / 5% spandex blend also gives a four-way stretch that plain polyester sleeves can't match.

FAQ
Do these actually block UV rays?
Yes — the Lycra fabric provides UV protection by physically blocking sun exposure on the covered skin. [VERIFY: UPF rating from Yoycol spec sheet]
Will they slip down during activity?
The 5% spandex content gives the sleeve enough grip to stay in place during movement. If you're between sizes, size down for a more secure fit.
Are they sold as a pair or individually?
As a pair — one order includes both the left and right sleeve.
Can men wear these?
Yes — the size chart is based on arm circumference and length, not gender. Men with upper arm measurements in the S–2XL range will find a functional fit.
How do I wash them?
Hand wash under 45°C (113°F). No bleach. No prolonged soaking. Air dry to maintain the print and elasticity.
Will the print fade after washing?
Dye-sublimation bonds color into the polyester fiber rather than coating the surface, so it holds up through repeated hand washing with proper care.
