Ice Silk Sleeves That Get Cold, Not Hot
Cover your arms in the sun and you cook. These arm sleeves are ice cold instead.
Ice silk fiber pulls your skin temperature down 3–6°C while it blocks over 98% of UV rays.
Cooling and coverage from the same fabric. Slide them on before the yard, the trail, or the drive — and skip the sunscreen ritual altogether.
A summer staple our customers reorder in a second color
✓ Cools your skin on contact
Ice silk fiber draws heat away as soon as it touches your skin, so covering up feels cooler, not hotter.
✓ Blocks over 98% of UV rays
Ice silk fiber does the sun-protection work of a strong sunscreen, without the reapplying or the residue.
✓ Stays light for all-day wear
Thin and breathable enough for a full day outdoors, from morning errands to evening walks.
✓ Fits the everyday outdoor lifestyle
Slides on before the yard, the trail, or the school run, then out of sight for the rest of your day.
✓ One fabric, two jobs
No separate cooling towel and separate sun sleeve — this pair does both at once.
