Robert's field journal

After cancer, covering up shouldn’t mean giving up the outdoors.

The right protection should help you keep doing what you love—not make hot days harder.

The reason Helios exists

The hard part isn’t knowing to cover up. It’s finding something you’ll keep on.

In 2018, WindRider owner Robert was diagnosed with Cutaneous T-Cell Lymphoma. The condition did not change his life expectancy, but its treatment increased his risk of melanoma. Covering up became part of every outdoor day.

He still wanted to be outside and on the water. What he did not want was a heavy long-sleeve shirt that felt like another reason to head indoors when the day got hot.

“It’s cool, it wicks, keeps you cool and dry and it’s silky smooth comfortable. Most importantly, as a physician and melanoma skin cancer survivor, it protects me so I can enjoy the beautiful gift of the great outdoors.”

Stanley’s Helios experience

“Having had a liver transplant, the anti-rejection meds make me more susceptible to the damaging rays of the sun. These shirts are the perfect solution. I have all 4 colors.”

Straight answers

Questions before you choose

Will long sleeves feel too hot?

Helios is designed for warm outdoor conditions with mesh ventilation, moisture-wicking fabric, and quick-dry performance. Customers regularly describe wearing it through full summer days.

What size should I order?

Helios has a modern athletic cut with four-way stretch. Choose your usual size, or size up if you are between sizes or prefer a roomier fit. The product page includes measurements for sizes S–5XL.

Does the UPF protection wash out?

The UPF 50+ protection comes from the fabric construction rather than a temporary topical coating, so normal washing does not remove it. Follow the care instructions on the garment.

Does a UPF shirt replace sunscreen?

No. UPF clothing protects only the skin it covers. Continue using appropriate protection on exposed areas and follow your clinician’s advice.

How quickly will my order arrive, and what if it does not work for me?

Orders are typically processed within 1–2 business days, and standard shipping usually takes another 2–5 business days. Helios is backed by a 99-day money-back guarantee; check the product page for current return details.
