No sting. Run on.

Most sunscreen migrates within the first climb. By the time you notice, you're wiping burning eyes mid-stride and losing your line. LifeJacket SPF 50+ Sun Gel absorbs in seconds, bonds under sweat, and goes nowhere for the whole run.

Why most SPF lets you down on the trails.

Standard sunscreen was designed for the beach, not for five hours of hard effort on technical ground. Sweat changes everything. Heat changes everything. Most formulas simply weren't made for this.

It runs into your eyes.

Sweat carries it straight off your forehead. By km 3 you're blinking through the burn, wiping your face, losing focus on the trail in front of you.

Too heavy to bother with.

That sticky, greasy film stays with you for the whole run. So you stop applying it. You head out unprotected and tell yourself it'll be fine.

Gone before the halfway point.

Applied at the trailhead, washed off by the first big climb. You've got hours left out there and nothing doing the job it was supposed to do.

Built for hours on the trail.

Trail running asks more of your SPF than a beach day ever would. Heat, sweat, technical terrain, hours of effort. This is what keeps up.

  • Stays put through sweat and steep climbs, no reapplication mid-run.
  • Absorbs in seconds with zero grease, so your skin feels ready to run.
  • Formulated without common irritants, so your eyes stay clear from start to finish.

★★★★★

"Ran an ultramarathon using this and mineral sun stick. Perfect pairing in Kenyan heat and altitude. I was only burnt in the places I didn't apply!"

Rebekah L. — Ultramarathon runner, Kenya veteran

★★★★★

"Applied it in the morning and kept me protected all day in uncharacteristically sunny/hot Snowdon conditions. No issues with the product running into my eyes and no sun burn even though I was out in direct sun for multiple hours. Would 100% recommend especially if you intend on sweating!"

Antony L. — Ultra trail runner, UTS 50k finisher

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.

I checked this product on a third-party rating app and it got a bad score. Should I be worried?

We'd say the same thing to our own families: no.

LifeJacket exists because skin cancer is 90% preventable and people aren't protecting themselves enough. What goes into our products matters to us more than it matters to most. So when a rating app flags one of our formulations, we take that seriously. And then we look at the science.

The ingredient flagged is Octocrylene, a widely used UV filter that's been approved under EU cosmetic regulations for decades. EU cosmetic law sets strict legal limits on the concentration of each ingredient permitted in a formulation. Those limits aren't arbitrary. They're the output of decades of scientific review by some of the most rigorous regulatory bodies in the world. We formulate within them. Every product we make is also independently safety assessed before it reaches market, with a review of the precise ingredient composition. That's the kind of rigorous, context-aware evaluation that tells you whether something is actually safe.

Rating apps can't do that. They flag ingredients by name, without knowing the concentrations in the finished product. That context is fundamental. Without it, you're not assessing safety. You're just reading a label.

We follow the law and the science. Not an algorithm.

We also believe in choice. If you'd prefer a mineral-based formula, our SPF 50+ Mineral Sun Stick uses zinc oxide and titanium dioxide and scores well on these apps. It's a brilliant product.

Can I pair this with UPF sun protection clothing?

Yes. SPF handles your exposed skin, UPF clothing handles everything it covers. Pairing this with UPF 50+ clothing means permanent UV protection woven into the fabric. No reapplication, no gaps. Together, you're fully covered.
