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.

Will these actually make me feel cooler?
Yes, the ice silk fiber pulls heat away from your skin on contact, so most customers feel a cooling effect right away.
Do they really block UV rays?
Yes, the fabric blocks over 98% of UV rays, similar to a strong sunscreen, without needing to reapply.
What size should I order?
The sleeves are designed to stretch comfortably over most arm sizes; check the size chart below if you're unsure.

Does the denim paneling feel stiff to wear?
No. The panels are placed at the neckline, lapels and sleeves to hold structure, not across the body. The parts that touch you most are soft ribbed knit.
Can I wear this as my actual jacket in fall?
Yes, in mild to cool weather. It's a substantial knit layer, so think crisp fall days over a tank or tee rather than deep winter.
Will the knit stretch out at the elbows and hem?
The ribbed construction is built to spring back, and the denim panels take the stress at the sleeves and edges. Hang it rather than folding it to help it keep its shape.
Does it close in the front?
It's designed as an open-front layer. That's what lets the denim lapels frame the outfit underneath.
