Why your current kit is leaving you exposed.

Most running kit wasn't designed with UV in mind. And most sun protection wasn't designed for running. On a long run in full sun, that gap matters.

Sunscreen sweats off.

Hard effort means heavy sweat. Within 30 to 40 minutes on a warm run, the sunscreen on your arms has broken down. You've got miles left. Your skin doesn't.

Long sleeves overheat you.

Most long-sleeve tops weren't built for running pace. They trap heat, hold moisture, and slow you down. You end up choosing between coverage and comfort. You shouldn't have to.

Your kit's protection fades.

Most UV-protective activewear uses a chemical treatment on the fabric surface. After around 20 washes, that treatment's gone. The tee looks the same. The protection isn't there.

Built for runners who go the distance.

Every element of this tee was built around one problem: staying protected, comfortable, and cool on long runs in full sun.

UPF 50+ woven into the fabric. Blocks 98% of UV, wash after wash.
Moisture-wicking and quick-dry. Stays comfortable at pace, however hard you're working.
Relaxed fit with dropped shoulders. Full range of motion, mile after mile.

"I bought this specifically for a summer trail ultra... The event was an 80k course... The shirt performed brilliantly. Super comfy, fairly cool, and the sun-protection really felt like it was working."

"Have been very impressed with this garment... I have used this for about two months now as a sun protection garment, and it has performed well. It does not wick sweat away as quickly as some Tech running shirts, but that is not its main purpose. However, it does not excessively hold moisture either. It dries quickly. The sun protection is where this excels."

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.
