🧢 Quick question: is your favorite hat actually protecting your scalp?

Most hats block some sun, but weaves, vents, and thin fabric can let UV rays straight through. And your scalp is one of the most exposed (and most overlooked) parts of your body.

Sundercover Hat Liners add certified UPF50+ protection to the hats you already own. No new wardrobe required.

Your favorite hat. Upgraded. ☀️

☀️⛳ Golf exposes you to hours of UV radiation, and it's not just coming from above. An 18-hole round typically means 4-5 hours in the sun, while grass and sand can reflect additional UV back onto your skin.

UPF 50+ apparel blocks approximately 98% of harmful UV rays, helping protect your skin from the first tee to the final putt.

Cover your skin. Protect your future. Play every round . ☀️

🍂 Fall hiking? The sun didn't get the memo. 🌞

Cooler air doesn't mean weaker UV. Here's the deal:

☀️ Up to 80% of UV rays can pass through clouds
⛰️ UV gets stronger the higher you climb, roughly 10-12% more per 3,000 feet
🍁 Fewer leaves = less shade on the trail

Stay vigilant with sunscreen and Sundercover® Long Sleeve Ts and Hoodies. Lightweight, breathable, and built to keep the sun off your skin from trailhead to summit. 🥾

Enjoy the views, not the burn.
