Long days need long protection.

You know the drill.

Sunscreen sweats off. Then you're exposed.

Sunscreen comes off when you sweat. Long runs, long rides: you need protection that stays put.

Long sleeves usually overheat you.

Most long-sleeve tops trap heat. You overheat, slow down, suffer.

Your activewear isn't protecting you.

Most UV-protective fabric gets there through a chemical treatment - not the weave itself. That treatment breaks down in the wash. After around 20 washes, the protection you paid for is gone.

What makes this different

Built to keep up with you.

Technical fabric engineered to manage heat, sweat and UV in equal measure. Moisture-wicking and quick-drying so you stay comfortable at pace. Relaxed fit with dropped shoulders - built to move with you, not against you.

What you get instead

UPF 50+ built into the fabric.

Protection woven directly into the fabric, not chemically added. Blocks 98% of UV rays wash after wash — one less thing to think about.

What you get instead

Runs cool, even when you don't.

Moves sweat away from your skin. Dries fast so you stay comfortable during high-intensity activity.

What you get instead

Protection that outlasts the wash.

The UPF rating is structural. Built into the 36-gauge high-density jacquard weave, not applied as a coating. The same 98% UV block after 100 washes as after the first. It can't wash out, because it was never a treatment.

How this fits

Relaxed fit. That's the point.

This top has a dropped shoulder and a wider body. It's intentionally loose so it flows as you move rather than pulling tight. Unisex, it works well on most body shapes in this relaxed silhouette. If you prefer a closer fit, size down. It'll still have some room to it. Not sure on size? Check the size guide for chest and length measurements.

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 weave. The tight construction physically blocks UV — making the protection structural, not chemical.

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

AS FEATURED IN

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.

These are a Game Changer
Great loose comfortable fit, great material and great performance as after being diagnosed with stage 4 melanoma last May I’ve now got to cover up.
These work and I can recommend effort especially if you have a similar condition. Fortunately the immunotherapy is giving me some fantastic results so it’s even more important for me to use Lifejackets from now on.
Thank you LifeJacket🙏😊
