You're training hard. Your protection shouldn't hold you back.

We've been there too.

Sunscreen slides off when you sweat.

That means every hour out there, you're less protected than when you started - and most people have no idea.

You're overheating out there.

Many technical and cotton tees hold heat against your skin. The longer a run goes, the harder your body works just to cool down - pace drops, effort climbs, and you're fighting your kit before you're fighting the course.

Treated UPF washes out.

Chemically-treated UPF washes out. After 20 washes, you're back to minimal protection.

Why we built this

Train hard without stopping to reapply.

Most sun protection is designed for the beach - something you apply once and then mostly ignore. We built this tee for people who are actually moving: running intervals, grinding out long rides, sweating through a summer session. The kind of training where stopping to reapply isn't just inconvenient - it just doesn't happen. UPF 50+ protection woven directly into the fabric means it doesn't wash off, sweat off, or run into your eyes. You put it on and forget about it. We built it because we live this way too.

PROTECTION IS BUILT IN.

Protection's built in. Our UPF 50+ fabrics block 98% of UV through structure, not chemicals. The weave does the work — so protection doesn't wash out, wear off, or fade over time.

WHAT'S IN IT AND WHY

UPF 50+ Fabric (72% polyester, 16% elastane, 12% rayon): blocks 98% of UV rays. Moisture-wicking pulls sweat away and dries quickly. Athletic fit tha'

OTHER USEFUL INFO

FABRIC INFORMATION

72% polyester, 16% elastane, 12% rayon

Comfortable and good sizing. Felt protected in the very strong Caribbean sunshine. Worked well with additional Lifejacket sunscreen.

Chris H - Caribbean tested

Bought 2 active tees white and blue for a trip to the Canary Islands. Great for by the pool or beach and smart enough to wear into a restaurant.

Stuart A - Canary Islands tested

A tighter fit than the casual tee so ordered a large in the active but medium in the casual. Nice fit and will be my go to for holiday sport wear.

UPF 50+ Active Tee

Here's how we're different.

UPF 50+ Active Tee	Big brand wicking tee
UPF 50+ lab tested and certified Guaranteed to block 98% of UV. We've tested it.	No UV testing or certification Guessing. Hoping. No idea what protection you're getting.
Engineered yarns and weave Technology built into the fabric itself.	Standard fabric construction Just a t-shirt. No UV consideration in design.
Skip sunscreen on covered skin Covered = protected. Simpler routine.	Still need SPF under your shirt Your "athletic top" isn't actually protecting you.
Flatlock seams No chafing after hours of movement.	Standard seams that rub Red marks under your arms by lunchtime.

Is this clothing chemically treated to offer UPF protection?

No. All of our clothing offers the UPF50+ protection it does due to the natural properties of the fabrics we use. This means you can wear and wash it over and over again, safe in the knowledge it will continue to keep your skin protected and you comfortable.

When will I get my order?

We try to get every order out the same day up until 4pm during the week. From then, please allow 2-3 business days for your order to arrive.

Who will be delivering my order and is there tracking?

We use a tracked service for nearly all of our deliveries. You will get an email from us when your order has been despatched which will include the tracking details.

How do your sizes compare to other brands?

We would say our sizing comes up true. This is a more relaxed fit than our other items and is oversized with a dropped shoulder. That shouldn't change the size you order and we would recommend ordering your usual size. If in any doubt check out the size guide towards the top of the page or give us a shout.

Can I return the product if I don't like it?

We’re happy to exchange or refund any clothing you're not 100% happy with. Just make sure it’s unworn and in perfect condition. To start a return, head to Returns and exchange and follow the instructions.

Where do you ship?

We ship to the UK and Channel Islands using a Royal Mail tracked service.

Who is LifeJacket for?

We're for anyone who wants to look after their skin and perhaps learn a little more about how to best achieve that. Whether you're a professional athlete, weekend warrior, dog walker, gardener or commuter, the science remains the same. Our products cater for every personal preference and environment, so it's just about finding what works for you.

Great t shirt
Bought 2 active tees white and blue for a trip to the Canary Islands. I’m not a fan of suntan cream and sometimes when your on You’re own it’s difficult to do your back. I’m 5ft 7 & 10 stone and I purchased small the fit was great and they were so comfy to wear to the point you felt like you were not wearing a top great for by the pool or beach and smart enough to wear into a restaurant Great product. Been looking at the long sleeve ones but just need more selection of colours.
