reported it became their go-to hoodie within the first wear.

Most sun shirts either overheat you the second you're out of the shade or feel paper-thin and cheap. The Coolchill™ Sun Hoodie uses ice silk cooling fabric that stays cool to the touch, with a UPF50+ rating built into the weave itself — not just a coating that washes out. It's built to be the layer you actually reach for, not the one that sits in a drawer after one hot afternoon.

The mask is built into the hood as one connected piece, not a separate attachment, so it holds its position whether you're running, casting a line, or just walking around. Adjust it up for full coverage or down around your neck when you don't need it — it's designed to move with you either way.

Yes. The fabric is engineered to resist pilling and losing its cooling properties over repeated washes, so it keeps its shape, softness, and UV protection over time instead of breaking down like cheaper polyester blends. Wash cold, hang dry for the best long-term results.

Cheaper sun shirts often use thin, single-layer fabric that loses its UPF rating after a few washes and traps heat instead of releasing it. The Coolchill™ Sun Hoodie uses ice silk cooling technology and a reinforced UPF50+ weave designed to actually perform outdoors — plus it comes with cooling towel and our 90-day guarantee, so you can try it risk-free.

You're covered by our 90-day money-back guarantee — wear it, wash it, take it outside, and if it's not the most comfortable sun protection you've ever owned, send it back for a full refund. No hassle, no fine print.

      Customers Are Living in Their New Favorite Hoodie

      "This is officially my go-to for every outdoor shift. It's so breathable I forget I'm wearing long sleeves, and the mask actually stays put instead of sliding down like every other one I've tried."

      Sarah M.

      VERIFIED BUYER

      "Wasn't expecting to love it this much honestly. It's cool, it's light, and I've gotten so many comments on how good the fit looks even with the mask up. Definitely ordering another color."

      Chloe K.

      VERIFIED BUYER

      "Bought this for fishing trips and now I wear it for everything — yard work, morning runs, even just walking the dog. It's just that comfortable in the heat."

      "Didn't think a hoodie could actually keep me cool in direct sun. Fabric feels premium, doesn't cling when I sweat, and the fit is perfectly athletic without being too tight."

        "Survived My Toddler and Three Loads of Laundry"

        I almost didn't buy this because I have a two-year-old who ruins everything within a week. Three months in and it still looks brand new — no pilling, no stretched-out cuffs, no fading. This is genuinely the only hoodie I own that's held up like this.

        "Finally, an Oversized Fit That Doesn't Look Sloppy"

        I've bought so many 'oversized' hoodies that just end up looking like a potato sack. This one actually drapes right — big enough to be comfortable but the cut still looks intentional. Wear it with joggers or just jeans and it works either way.

        "My Home Office Uniform Now"

        Work from home four days a week and this has basically replaced every other sweatshirt in my closet. Soft enough for back-to-back Zoom calls all day, warm enough for my house in the winter, and somehow still looks decent enough that I don't have to change before a walk outside.

        "Bought One, Immediately Ordered Two More"

        Wasn't expecting much given the price, but the second it arrived I could tell the fabric was a different tier than what I normally get. Ordered the black first, then went back for navy and gray within the same week. That never happens.

        "Held Up Through an Entire Ski Season"

        Wore this under my jacket almost every weekend on the mountain from December through March. No pilling from the friction against my shell, still holds its shape, and it's warm enough that I sometimes skip a base layer entirely.

        "The Only Gift That Actually Got Used"

        Got this for my husband as a random gift and he's worn it at least twice a week since. He's picky about how things fit and even he admits the sizing is spot on. Already looking at getting him a second color for his birthday.

          Wear this on every charter now. The mask actually stays put even with wind coming off the water, and I'm not dealing with sunburn on my neck anymore. Ordered the 3-pack so I always have a clean one.

          Didn't expect to like the mask feature as much as I do — pull it down when I don't need it, up when the sun's brutal. Fabric feels way lighter than I thought it would based on the photos.

          Sized up based on the reviews and glad I did — fits true once you go one size up. Material is soft right out of the bag, not scratchy like some of the cheaper ones I've tried."

          Bought the 6-pack for the whole work crew since we're outside all summer. Everyone's actually been wearing them, which says a lot — usually half this stuff sits in a truck.

          Honestly bought this because it looked cool in a video, wasn't expecting much. The cooling fabric claim is legit though — noticeably cooler than a regular long sleeve on a hot day. Would buy again.

          Running in this during peak heat and it's a completely different experience. No chafing, breathes better than my old sun shirt, and the mask doesn't fog up my sunglasses like I worried it would.
