Mat Viper
BJJ · MMA · APPAREL · SHOPIFY LIQUID

A fightwear brand I built to understand the whole machine.
Mat Viper is the BJJ and MMA apparel brand I've designed and operated since 2019. I own every part of it: product design, athlete collaborations, Shopify maintenance, photography, packaging, fulfillment decisions, and the parts of brand work that only show up after the order leaves the building.

01 / BRIEF
The Brief
Mat Viper is not client work in the usual sense. It is a live product business I operate, which makes every design decision accountable to inventory, production cost, photography, launch timing, customer support, and whether the product survives real training.
The assignment was never to make another combat-sports graphic brand. The assignment was to build a fightwear system that could hold up next to serious athletes without losing the weirdness and specificity that make independent apparel worth buying.
02 / APPROACH
The Approach
That sounds like marketing language. It's actually an IA decision and an operational decision: every signature drop is a real collaboration with a real fighter, not a design brief I wrote in a vacuum. Bryce "Thug Nasty" Mitchell's chopped-wood t-shirt exists because that's an actual thing he's known for — not a graphic somebody invented to sell. The work is rooted in the people, and that means the brand has somewhere to go that isn't more graphics.
Iconography over decoration
Sublimated full-coverage rashguards are the easy mode of BJJ apparel — you can fill every square inch with whatever pattern you like, and a lot of brands do. Mat Viper's signature pieces lean toward iconography: a single mark, a single piece of architecture, deliberate negative space. A design that resolves as a clean lockup will outlast a graphic that depends on this season's gradient palette. The principle is restraint as a way to last. Loud designs date in a season. Iconography survives the trend cycle.
03 / BUILD
Build & Implementation
The storefront runs on Shopify. I customized a Liquid theme rather than building one from scratch — the right call for a brand where my time is better spent on product design, photography, and athlete relationships than on rebuilding theme architecture. I maintain it myself. The product photography is shot in-house.
That choice matters because Mat Viper is an operator brand. The site has to support drops, product detail pages, collection logic, email capture, and day-to-day catalog edits without becoming a technical project every time a new product is ready.
Site Care is the same maintenance discipline applied to client sites: hosting, updates, and small changes handled without turning every live edit into a new project.
04 / RESULT
The Result
Mat Viper has shipped signature work with named athletes including UFC fighter Bryce "Thug Nasty" Mitchell. The catalog runs across rashguards, t-shirts, shorts, and capsule drops, with ongoing signature work alongside the core line. Working pros in the BJJ and MMA communities wear the gear in their own training and competition without anything attached to it. The site is live and the brand is in steady operation.
The point of the brand is not that it is large. The point is that it is real. The feedback loop is direct: design the thing, shoot it, launch it, sell it, support it, watch it get trained in, then make the next thing sharper.
05 / NEXT
What I'd Do Next
The next useful sprint is editorial depth: stronger product stories, more in-environment photography, and a lookbook system that makes each drop feel collected instead of simply listed. The product already has a point of view. The page system should carry more of that weight.
FAQ / BUYER QUESTIONS
Do you take on client work for apparel brands like Mat Viper?
Yes. Mat Viper is useful proof because it shows the parts of apparel work that are hard to fake: product thinking, ecommerce structure, photography, launch cadence, and maintenance after the first drop.
Can you build on Shopify without starting from scratch?
Yes. A customized Liquid theme is often the right move when the business needs speed, maintainability, and a controlled visual system more than a fully bespoke theme architecture.
Do you design the product graphics too?
Yes. The strongest apparel work happens when product graphics, photography, storefront hierarchy, and launch copy are treated as one system.
