Shopify Plus Case Study
Shopify Plus Design, Development & Growth
Proviz makes reflective sportswear and accessories for runners, cyclists and outdoor adventurers, and has spent 15 years building a name for kit that keeps people seen in the dark. With more than a million customers, its Shopify Plus store sits at the heart of the business, and it needs to keep getting better. Proviz works with Charle as an ongoing design, development and growth partner. Each month our team plans, designs and ships a block of improvements to the store, from conversion and usability fixes to performance work and bigger, campaign-led features. The most visible of these so far is NIGHT MODE, a one-tap toggle that shows how Proviz's reflective products look at night, built for the biggest marketing campaign in the brand's history.
Rather than one big rebuild every few years, Proviz improves its store continuously. Each month we agree a block of work with the Proviz team, then our designers, developers and QA take it from idea to live. Our account team runs the roadmap and keeps priorities clear, so the store gets better every month without Proviz having to manage developers day to day. Some months that means a run of quick wins. Others it means a bigger piece of design and development, like NIGHT MODE. Either way, the work is planned around what will make the most difference to Proviz's customers and its commercial goals.

Much of the growth work happens in the details of the shopping journey. We added approximate restock dates to Proviz's Klaviyo back-in-stock popup, so a customer waiting on a sold-out size knows when to expect it rather than shopping elsewhere. On mobile, a sticky utility bar keeps sort and filter controls within reach as shoppers scroll a collection. We've reworked the size selector on product pages, made tablet navigation open properly on the first tap, and are expanding product recommendation blocks to show every colourway rather than capping them at three. Behind the scenes, we're improving Core Web Vitals, with work on interaction speed (INP) so the store feels quick on every device.

Reflective kit is bought for the moments nobody photographs: the dark commute home, the winter run before sunrise. In a studio shot, a REFLECT360 jacket looks like a good jacket. At night, it looks like nothing else on the market. Proviz had the night photography, so we designed and built NIGHT MODE to put it in front of shoppers at the moment they're deciding.
One toggle switches the store between day and night. On the homepage, the hero fades from runners on the Thames at dusk to the same runners glowing against the city lights. On collection pages, the toggle sits in the filter bar and turns every product card to its night image at once, so shoppers can compare how each piece performs in the dark. On product pages, it lives on the main gallery image, right where the shopper is already looking. No page reloads and no pop-ups, just an instant before and after that lets the product sell itself.

"A big thanks to Charle for bringing this to life. We are super chuffed and feel this addition, as well as improvements across the whole website, now put Proviz Sports up there with some of the very best Shopify e-commerce websites."
NIGHT MODE launched alongside Proviz's new Autumn collection as the digital centrepiece of the biggest marketing activation in the brand's 15-year history. The campaign runs well beyond the website, with content creator partnerships and Proviz's first ever 5K NIGHT MODE running event in Manchester, which sold out within a week of tickets going on sale. Every one of those activations sends people back to the store, and the toggle gives them something to try the moment they land.
Since launch, we've kept refining NIGHT MODE alongside the rest of the monthly roadmap. For Proviz, the store is never finished, and that's exactly how we like to work.
