Features and Benefits:

Fabric blocks 90% UVB rays and provides a cooling sensation when wet
Softcover elastic on upper arms to keep them in place
Reflective logos for increased low-light visibility
We are often imitated. Remember just because it is white, it does not mean the fabric will cool you. READ ON!

INSTRUCTIONS: It is best to put the entire sleeve onto your wrist, then slowly “push" the sleeve up rather than pulling it up, then once above the elbow, gently pull up to the bicep. When removing it, “push” then sleeve down using the thumb and fingers around the bicep opening.

What makes ours different? Our Skin Cooler fiber is designed to feel and perform like silk (from a silkworm). Through Biomimicry, we took the virtues of this natural fiber and created a synthetic silk. It will keep you cool in hot weather and cooler when it is wet. Put it on and you will instantly feel the cool sensation. Wet it and you will notice a drop in the surface temperature of the skin between 7 and 10 degrees.

Do the colored fabrics, or sections with logos affect the cooling technology? No! You will notice the fabric on the inside is all white despite the outside color or logos of the Skin Cooler product The sublimation process we use to place logos or color on our fabric turns the ink into a gas that adheres only to the outside of the fabric. Therefore this ink is non-absorbent and does not affect the technical integrity of the product in any way. The colored parts of the products will keep you just as cool as the white.

What about black? Our solid black Skin Cooler garments which are yard-dyed black instead of sublimated. This is why the fabric inside is black inside and and out. The actual fibers are dyed before knitting it into fabric. We estimate the black might add between 1° and 3° F depending on the ambient temperature and humidity.

You want the Arm Cooler measurement at the Top Opening to be smaller than your bicep measurement. The elastic holds the Arm Cooler in place.

A MEDICAL TESTIM0NIAL: We received this letter from a respected Dermatologist and Mohs Surgeon:

I am an avid runner and triathlete and I recently discovered your Skin Cooler products, of which I'm a huge fan. I have been wearing them for a few months now and couldn't be happier. I am a dermatologist and Mohs surgeon. Every patient I see is plagued by basal cell carcinoma, squamous cell carcinoma, or melanoma. I recommend your products to my active patients on a daily basis. It allows them to continue their active lifestyle while protecting themselves from the sun. I find your product to be far superior to all other cooling and sun protective lines. I truly appreciate your efforts and innovations.

Note: No garment should ever be a substitute so we always recommend you wear sunscreen underneath these, and all, products. It is crucial to keep in mind that a sunscreen's (whichever brand you may choose) SPF/UPF rating refers only to its ability to protect skin from UVB radiation. Because we know that UVA damage can be just as insidious, it is essential for the health of your skin that you use a sunscreen that contains the UVA-protecting ingredients of titanium dioxide or zinc oxide.
