Why sunscreen alone fails in the water.

Sunscreen was designed for the beach. Not for hours of paddling, sailing, or surfing. Once you're in and out of the water, the rules change completely.

Water strips it off.

Every splash, every wave washes sunscreen away. After 40 minutes of real watersport use, most of it is gone.

Reapplication isn't practical.

You're mid-session, hands are wet, you're back in the water in two minutes. Proper reapplication doesn't happen. Your shoulders pay for it later.

Old rash vests restrict you.

Traditional rash vests are thick, tight, and stiff. Functional in the water, uncomfortable the moment you step onto land. You end up leaving it off.

Why watersport athletes use LifeJacket.

Most watersport kit protects you from the cold or the friction. This protects you from the one thing the water can't wash away.

UPF 50+ built into the fabric. Put it on once, protected all session.
Lightweight and quick-drying. Comfortable in the water and straight off the beach.
Four-way stretch and quarter-zip collar. Moves with you, looks right anywhere.

"Comfortable and form fitting without being restrictive. Withstood abuse of hours in small racing dinghies without signs of wear. Even when wet it was still comfortable without feeling cold or claggy."

UPF 50+ Active Tee

How to find your size

Chest

Wrap a tape all around the fullest part of your chest. Take that measure and use the ‘TO FIT CHEST’ column to find your size. An even better way, is to grab something you love the fit of. Lay it flat and measure from armpit seam to armpit seam. Cross check that against our ‘PIT TO PIT’ garment measure.

Length

Got a top that’s the perfect length? Lay it flat and measure from the shoulder seam all the way to the bottom hem, in a straight line. Cross check that against our ‘LENGTH’ garment measure.

This tee is cut straight from top to bottom making it more of an athletic fit. It has four-way stretch so it moves with you.

Size	To fit chest (cm)	Pit to pit (cm)	Length (cm)
XS	84–90	46	65
S	90–96	49	68
M	96–102	52	70
L	102–108	55	73
XL	108–114	58	75
XXL	114–120	61	78

Between sizes? Size up if you prefer a looser fit. These tees have a straight, athletic cut.

Chest

Length

Got a top that’s the perfect length? Lay it flat and measure from the shoulder seam all the way to the bottom hem, in a straight line. Cross check that against our ‘LENGTH’ garment measure.

Relaxed, slightly boxy fit with a dropped shoulder seam. This is designed to be loose intentionally so it flows as you move rather than pulling tight. If you prefer a closer fit, size down - it will still have some room to it.

Size	To fit chest (cm)	Pit to pit (cm)	Length (cm)
XS	84–90	48	66
S	90–96	51	68
M	96–102	54	70
L	102–108	57	72
XL	108–114	61	74
XXL	114–120	65	76

Between sizes? This top has a dropped shoulder and a wider fit. It's intentionally loose and flows as you move. Size down for a closer fit, but it'll still be relaxed. That's the design.

L	102–108	57	72
XL	108–114	61	74
XXL	114–120	65	76

Between sizes? Same fit as the Long-Sleeve Active Tee. Dropped shoulder, intentionally wide and loose. Size down if you want it closer to the body, but it'll still be relaxed.

Chest

Length

Got a top that’s the perfect length? Lay it flat and measure from the shoulder seam all the way to the bottom hem, in a straight line. Cross check that against our ‘LENGTH’ garment measure.

A straight, relaxed cut that fits true to size. It sits comfortably without pulling or feeling restrictive.

XS	84–90	47	62
S	90–96	50	65
M	96–102	53	67
L	102–108	56	70
XL	108–114	59	72
XXL	114–120	62	74

Between sizes? Size down if you prefer a slimmer look. This top has a straight, relaxed fit.

Designed to fit close so it doesn't bunch or ride up in the water. Not skin tight like a traditional surf vest, but a snug, secure fit is intentional. It's a thinner, softer fabric than traditional rash vests. The four-way stretch gives enough room to move comfortably whether you're paddling, surfing, or swimming. If you're between sizes, size down.

Size	To fit chest (cm)	Pit to pit (cm)	Length (cm)
XS	84–90	44	73
S	90–96	47	75
M	96–102	50	77
L	102–108	53	79
XL	108–114	56	81
XXL	114–120	59	83

Between sizes? The pit-to-pit looks smaller than your chest size. That's intentional. Four-way stretch means it moves with you. If in doubt, size up.

Head circumference

Wrap a tape measure around your head, about 2cm above your ears. That’s your Head circumference. The hat has an adjustable cord, so you have a range within each size.

Available in small, medium, and large. The adjustable elastic cord lets you dial in the fit within each size, so if you're between sizes you can still get a comfortable, secure result. We'd suggest sizing up and tightening with the cord. The neck strap keeps it on when the wind picks up. When you don't need it, tuck it inside the hat.

Size	Head circumference (cm)
Small	62
Medium	64
Large	66

One size fits all. The adjustable drawcord tightens or loosens to fit any head size. A neck strap keeps it on in the wind. Tuck it inside the hat when you don't need it.

"Really like a rash vest designed with SUP and kayaking in mind - the design and the pockets are a big plus for me!"

Matt — Kayaker & SUP paddler, detail-focused reviewer

How we're different.

UPF 50+ Rash Vest	Skin-tight surfing rash guard
Stylish enough for the beach bar Water to restaurant without changing.	Only looks right in the water Skin-tight technical look. Boardshorts only.
Lightweight, relaxed fit "So comfy to wear all day" - real review. Flattering on real bodies.	Heavy, tight, restrictive Peeling it off is a workout. Shows every contour, feels restrictive.
Dries in minutes Out of water, dry before your drink arrives.	Stays wet for hours Cold, clammy, uncomfortable.
UPF 50+ certified Tested, guaranteed, reliable protection.	Assume it protects because it covers Hope is not a sun protection strategy.

★★★★★

"Excellent product good sun protection when swimming and dries very quickly. The top has been worn many times in the sea and still holds its shape and quality of material."

Paul H. — Sea swimmer, regular ocean sessions

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 (86% polyester, 14% elastane) - Blocks 98% of UV. Protection is structural, not chemical. Won't wash out.

OTHER USEFUL INFO

Machine wash 30°C | Hang to dry | UPF built into the fabric (won't wash out) | Available S/M/L/XL

FABRIC INFORMATION

86% polyester 14% elastane

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.

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.

What if I'm not in when it's delivered?

The majority of our products fit through the average letter box. In the event your order doesn't, Royal Mail will leave a card letting you know they tried to deliver and what the next step is (either your order was left in a safe place or it has been returned to your local sorting office where it can either be collected, or a redelivery booked).

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.
