Why your current setup is leaving you exposed.

Most sunscreen was designed for the beach, not a four-hour effort in direct sun. Most long-sleeve activewear wasn't designed with UV in mind at all. The gap between those two facts is where skin damage happens.

Sunscreen sweats off.

Forty minutes of real effort and most SPF is gone. On a long day outside, that leaves hours of unprotected exposure you can't see and can't feel until later.

Long sleeves overheat you.

Standard long-sleeve tops trap heat and hold moisture against your skin. You slow down, you overheat, and you usually strip the layer off. There goes your UV defence.

Your kit isn't protecting you.

Most UV-rated activewear uses a chemical coating applied to the surface of the fabric. Around 20 washes in, that coating has degraded. The UPF rating on the label no longer reflects what you're wearing.

Why outdoor athletes wear LifeJacket.

Built for long hours outside. When sunscreen washes off under sweat and effort, this stays put.

UPF 50+ woven in, blocks 98% of UV from the first wear to the fiftieth.
Moisture-wicking and quick-dry, stays comfortable at pace in full sun.
Relaxed fit with dropped shoulders, full range of motion for every discipline.

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).

"Excellent protection against the sun... easy to wear and even though it has long sleeves it didn't feel any warmer than a short sleeved tee shirt. Thoroughly tested on a Tour of Mont Blanc in 30+° temperatures."

★★★★★

"Very comfortable to wear. Love the looser style as allows the air to circulate. Stays fresh. I wore the top 3x on long hilly walks before I washed it. It gives me confidence to enjoy the outdoors."

Joanne S. — Melanoma patient, daily outdoor walks

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.

What is the point of UV protection in clothing and are all long-sleeve shirts UV protective?

UPF refers to the Ultraviolet Protection Factor which is a UV rating system that’s used for fabrics, similar to SPF for cosmetics. It indicates how much UV radiation can penetrate the fabric of the top.

A fabric that’s rated UPF 50+ blocks 98% of the sun's rays, offering very high sun protection. UV protective clothing works by absorbing or reflecting the sun's UV radiation, preventing it from reaching your skin.

Long sleeve shirts with UV protection help shield your skin from harmful UV rays, reducing the risk of skin damage, heat stroke and skin cancer.

Not all long sleeve shirts offer UV protection. It depends on the fabric, yarn, weave and treatment used in the shirt's production.

You can read more about it here.

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.

Are your long-sleeve shirts with UV protection suitable for all outdoor activities including swimming?

Yes, our long sleeve shirts with UV protection are designed for a variety of outdoor activities, from hiking to swimming.

If you’re likely to be sweating or are particularly active, our active tops would suit you best. Our rash vest is ideal when in or by water. If you’re just outside in strong sun and want a more casual look, that’s where our casual tops would be best suited to your needs.

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.

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.
