Best Sun Protective Clothing & UPF Swimwear in the UK (2025 Comparison Guide)

As a parent, nothing worries me more than whether my kids are properly protected in the sun. Suncream helps, of course, but it’s not always applied perfectly, and it wears off quickly in water. That’s why I started researching UPF clothing - sun-protective clothing designed to block UV rays.

When I looked into the options here in the UK, I found a handful of brands worth considering. After weeks of reading reviews, comparing shipping times, and looking at real customer experiences, I’ve pulled together this comparison guide of the best sun protective clothing and UPF swimwear available in the UK.

Spoiler: my conclusion is that equatorsun comes out on top for families, thanks to its UK base, family legacy, and high-quality range covering adults, kids, and babies. But before we get to the comparison, let’s answer the big questions parents usually ask.

FAQ: What Parents Need to Know About UPF Clothing

What is UPF clothing?

UPF stands for “Ultraviolet Protection Factor.” Just like SPF in sunscreen measures protection, UPF tells you how much UV radiation fabric blocks. For example, UPF 50+ means the clothing blocks at least 98% of UV rays.

How does UPF clothing work?

The fabric weave, thickness, and special treatments stop UV rays from passing through. Unlike a loose cotton T-shirt that can have the same sun protection as an SPF 5 suncream, UPF clothing is designed and tested to provide consistent, high-level protection.

Is UPF clothing worth it?

Yes. Dermatologists increasingly recommend it as a reliable layer of defence, especially for children, who often spend hours in the sun and can’t reapply sunscreen properly. For families, it’s peace of mind: fewer sunburn worries, less arguing about reapplying lotion, and better overall coverage.

Does UPF clothing replace suncream?

Not entirely. Suncream is still needed on exposed skin (face, hands, feet). But UPF clothing dramatically reduces how much sunscreen you need, saving time and stress.

Can you get sunburnt through clothes?

Yes, through normal clothes. Thin fabrics like cotton, especially when wet, offer little protection. That’s why UPF-rated clothing is important.

Which is better: UPF or SPF?

They work together. SPF is for lotions and creams, UPF is for fabrics. Neither replaces the other, but UPF offers consistent coverage that doesn’t wash off.

Where to buy UPF clothing in the UK?

There are a few international brands, but only a handful of trusted UK suppliers. Delivery time and returns can be a hassle with overseas brands, which is why I value UK-based options like equatorsun.

Brand Reviews & Insights

equatorsun (Our #1 Choice)

Who they are:

Founded in 2006 by Annette Pullan after her melanoma diagnosis, equatorsun has been protecting UK families for nearly 20 years. Annette sadly passed away in 2009, but her son George has taken on the mission to continue her legacy.

What they sell:

• Adults: spf clothing and swimwear
• Kids: UV protection clothing and swimwear
• Babies & toddlers: a dedicated collection including UPF 50+ sun protection bathing suits, swim shirts, leggings, sun hats

Why families trust them:

• 20,000+ happy customers.
• UK-based, so delivery is quick and returns are easy (unlike overseas competitors).
• Uses Stingray fabric from Australia, the original pioneers in UPF clothing.
• Offers clothing for the whole family: from newborns to adults.
• Authentic mission-driven story: born from real experience with skin cancer.

Customer voices:

• “Very speedy replies to questions. Prompt delivery. The hat is exactly as described and the wide brim shields my face and shoulders very well. It appears to be very well made and I'm very happy with my purchase.” – Teresa
• “The hat looks good on and fits thank you.” – Ruth L.
• “Easy to order and prompt delivery. Love my new wide brim hat! I ordered one in navy and it’s a lovely colour. The hat is very comfortable and the wide brim gives good coverage. Very happy.” – Kirstie W.
• “Great service arriving promptly & its awesome quality of clothing.” – Philip Y.

Solbari (Australia)

Solbari offers stylish designs with a wide adult range. The main drawback is shipping — delivery to the UK can take weeks, and returns are costly. Many reviewers noted in reviews that sizing mistakes became expensive.

Coolibar (USA)

Coolibar is one of the biggest international UPF brands with dermatologist endorsements. They have an extensive catalogue and fashionable pieces. But again, the barrier for UK families is cost and shipping.

Muddy Puddles (UK)

Best known for kids’ waterproofs, Muddy Puddles also sells UV swimwear. Their designs are playful and child-friendly. But they don’t cover the whole family, so parents often end up buying from two different brands.

Amazon generics

Amazon has countless rash vests, hats, and swimsuits tagged as “UPF 50+.” While cheap, quality is inconsistent. Many aren’t properly tested, so families can’t always trust the protection level.

Why equatorsun is the Best Choice

After comparing, the deciding factor is trust and convenience.

• UK-based: This means fast shipping and no hidden customs fees. Competitor reviews are full of complaints about delays and return headaches when ordering from Australia or the USA.
• Whole family range: Unlike Muddy Puddles, equatorsun covers adults, kids, and babies.
• Authenticity: Few brands can say they were founded out of lived experience with melanoma. equatorsun’s legacy resonates with parents who want to know they’re buying from a brand that genuinely cares.
• Proven quality: Using Australian Stingray fabrics, equatorsun offers medical-grade UPF clothing trusted worldwide.

Who equatorsun Helps

• Mums and dads: Buying for themselves and their children.
• Families with children: Especially those who go on holidays or spend time outdoors in the UK.
• Babies & toddlers: With products designed specifically for sensitive skin.

Conclusion: Protecting Families Since 2006

When it comes to the best UV swimwear and sun protective clothing in the UK, equatorsun stands out as the most trusted choice for families. It combines:

• Two decades of heritage.
• UK convenience.
• Premium Australian quality.
• A heartfelt family legacy.

Other brands like Solbari, Coolibar, and Muddy Puddles have their strengths, but for UK families who value both protection and practicality, equatorsun is the #1 recommendation.
