SPF that won't sweat off.

Sunscreen and running don't mix. Sweat it off in the first mile, and you're unprotected for every mile after. The LifeJacket UPF 50+ Active Tee has protection woven into the fabric. It can't sweat off, ever.

Why your current sunscreen fails on a long run.

Sunscreen was designed for the beach. Not intervals. Not trail running. Not two hours at threshold. Under real running effort, most protection is gone before you've warmed up properly.

It sweats off by mile three.

The harder you push, the faster sunscreen breaks down. After 40 minutes of real effort, most of what you applied is on your collar, not your skin.

Your tee is cooking you.

Cotton and basic technical tees trap heat against your body. The longer the run, the more your kit fights your pace. Not the course.

Treated UPF washes out.

Chemically treated UPF clothing sounds good until 20 washes in. After that, you're running in a regular tee with nothing but optimism between you and the sun.

Built for runners who don't stop.

You're not standing still. Your kit needs to keep up. Here's what the UPF 50+ Active Tee does when the effort climbs.

UPF 50+ woven in. Blocks 98% of UV every single run.
Moisture-wicking fabric moves sweat off your skin as you push.
Structural UPF never washes out, however many miles you log.

UPF 50+ Active Tee

Unisex fit, straight cut through the body

●Go by your chest measurement in the table below.

●Wider hips than chest? Size to your hips (double the 'pit to pit' to check it clears them).

The fit

Straight cut Athletic fit Four-way stretch

Close-fitting and true to size. If you normally wear a medium, this is a close-fitting medium, not loose or relaxed.

How to measure

The diagram shows the garment laid flat. Two ways to find your size:

●Measure your chest around the fullest part, then use the To fit chest column.

●Or measure a top you own laid flat, then match the Pit to pit and Length columns (both shown on the diagram).

"This Tee is comfortable and lightweight. I have used active wear with SPF from sports brands, more expensive, and this easily stands up against them. Highly recommend."

William P. — Activewear buyer, tried pricier brands

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

90% polyester, 10% spandex. Four-way stretch for full range of motion without restriction.
Performance matt yarn. Moisture-wicking, quick-drying, comfortable at pace.
High-density jacquard knit. The tight construction and the polyester fibre itself block UV, so the protection is built in rather than applied on top.

OTHER USEFUL INFO

Gentle machine wash 30°C | Hang to dry | No tumble dry, no iron, no bleach | UPF structural not chemical | Available XS/S/M/L/XL/XXL

FABRIC INFORMATION

90% polyester, 10% spandex

Built from personal experience.

When several close friends, including Jono, were diagnosed with cancer in their thirties, it changed everything. LifeJacket was born to make everyday skin protection simple, reliable and part of normal life.

GOOD TO KNOW.

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.
