Jamie Siminoff says UV-protection shirts should be sold in sunscreen bottles, not the apparel aisle

Jamie Siminoff looked at a UV-protection clothing company and basically said: you’re not selling shirts, you’re selling sunscreen that happens to have sleeves. His advice to L-Cube Lifestyle founder Eric Alexson was wonderfully insane in the way good founder advice often is, put the shirt inside a sunscreen bottle and sell it in the sunscreen aisle.

That is the sort of sentence that makes a How I Built This advice episode earn its existence. Not because it is guaranteed to work. Please imagine the planogram meeting where someone has to explain a hoodie in a Coppertone-shaped tube. But because Siminoff immediately got to the thing most founders dodge: the product’s real competitor may not be the company across the aisle. It may be the aisle itself.

The aisle is the ad

Alexson’s company sells UV-protective shirts, hoodies, hats, and is looking at shorts, leggings, and skirts. His pitch was technical but sensible: mechanical sun protection, backed by a Mohs surgeon and dermatologist, with fabric rated UV 50 rather than a typical shirt’s lower protection. This is real product stuff. It is also the kind of explanation that can slowly kill a brand while everyone nods politely.

education eats margins, right? That is like as clear as day education eats margins.

That was Scott Tannen, and he was right. The minute your product requires a TED Talk at shelf, your customer acquisition cost starts putting on ankle weights. This is the same problem that eats wellness gadgets, better-for-you snacks, and half the objects in the REI checkout area. The founder knows too much. The shopper is trying to remember whether their kid needs SPF 30 or SPF 50.

you know what I’d, how I’d be selling this. I’d be making sunscreen bottles with the shirt inside of it and selling it where sunscreen is.

This is classic Siminoff, and also classic entrepreneurship brain: find the existing behavior, hijack it, and make the customer feel like they already understand the invention. Ring did not have to educate America on what a doorbell was. It just made the doorbell paranoid, networked, and camera-ready. As Siminoff put it, the pre-awareness of the doorbell gave him “billions of dollars of marketing and a hundred years of knowledge.”

For L-Cube, his argument was that UV apparel should stop fighting the athleisure rack. Nobody walking past a wall of performance shirts wants a lecture on polyamide weave density. But someone in the sunscreen aisle is already worried about sun damage, chemicals, kids, sports, Florida, aging, cancer, and the sticky indignity of reapplying lotion in public. That shopper has the problem in hand. Literally.

The weak part is the sunscreen panic

Siminoff did wander into shakier territory when he declared, as a consumer, that sunscreen is “not good for you.” Guy Raz, perhaps seeing a small army of previous sunscreen founders rising from the sea like SPF-coated Avengers, immediately cautioned him not to say all sunscreen is toxic. Good. The medical claim is not the best part here, and it doesn’t need to be. Dermatologists already recommend UPF clothing as a strong tool for sun protection. Sunscreen still has a job. Hats still have a job. Shade, the original technology, remains undefeated.

It’s just like, you’re in the weeds again. Like I’m replacing sunscreen.

Still, Siminoff’s sharper point survives the sunscreen theatrics. If L-Cube can credibly say, “wear this instead of slathering your arms every hour,” the company has a cleaner enemy, a clearer shelf, and a much better story. That’s not just branding. That’s retail judo.

The bottle idea might be too cute. The aisle idea is not. Founders love to explain what makes the product different. Customers prefer knowing what job it does before they’ve finished blinking.

Mechanical sunscreen in the bottle. I see it on the thing. Know exactly what to do with it. Pre-awareness. Boom.
