Boys’ long-sleeve UV T-Shirts – everyday protection with effortless style
Because sun protection shouldn't slow him down
Some kids won’t stop moving—and we wouldn’t want them to. That’s why at Juillet Juillet, we’ve created a line of UV-protective long-sleeve T-shirts for boys that delivers serious sun safety, without ever compromising on comfort, breathability, or freedom.
Perfect for outdoor play, seaside adventures, or long summer walks, these tops offer lightweight, full upper-body coverage, with a refined, sporty silhouette boys can wear all day.
Whether worn on their own or layered with UV shorts, these T-shirts are a cornerstone of a complete sun-safe wardrobe.
High-performance sun protection, no chemicals added
Made from UPF 50+ certified technical fabric, our long-sleeve T-shirts block more than 98% of UVA and UVB rays—without any added chemical coatings. The protection is woven directly into the fabric, remaining effective wash after wash, swim after swim.
The design offers coverage across the shoulders, arms, chest and back—those zones that are most often exposed and frequently forgotten during sunscreen reapplication. While SPF remains essential for uncovered areas, this top takes care of the rest.
It’s an easy win for both children and parents: less time worrying, more time enjoying the sun.
Breathable comfort for active days
These long-sleeve UV tops are built to follow the rhythm of summer. The lightweight material keeps him cool and dry, even in full sun. The soft, stretchable seams prevent irritation, and the cut is tailored for movement—whether he’s chasing waves, climbing rocks, or napping in a hammock.
Worn over a UV swim boxer or styled with casual pieces off the beach, the top transitions smoothly between swimwear and daywear. It’s one of those rare pieces that feels just as good in action as it does at rest.
Bold, clean, and quietly confident
At Juillet Juillet, design is never an afterthought. Our boys’ UV T-shirts combine sun protection with effortless style, using graphic lines, deep colours, and timeless simplicity. The look is bold, but not loud—perfectly aligned with our vision of functional, refined kidswear.
These T-shirts mix easily with other items from the Boys Collection, making them a smart and stylish base layer for any sunny-day adventure.
In a nutshell
Juillet Juillet's Boys’ Long-Sleeve UV T-Shirts deliver serious sun protection with breathable comfort and understated style.
With UPF 50+ certified fabrics and a design made for movement, they’re the ultimate go-to for boys who live outside—and for parents who want peace of mind.
