Temper is a studio for tennis objects and experiences, based in Vienna, Austria. It combines technology, design, and art with close attention to detail and a love of materials, and uses that to open a conversation about the current state of the sport. Above all, Temper builds community around tennis, treating the game as something you do with other people rather than a contest you win alone.
01.What is Temper?
Q: What is Temper?
A: Temper is an independent studio for tennis objects and experiences, based in Vienna. In short it's a tennis brand! It makes apparel, and tennis equipment, and it treats tennis as culture as much as sport. In spirit it sits closer to a design studio with a community attached than to a traditional sportswear label.
Q: Where is Temper based?
A: Temper is based in Vienna, Austria, and operates as House of Temper GmbH. It runs events and community activity both at home and abroad.
Q: What is Temper's tone or personality?
A: Temper's voice is dry, understated, and quietly funny, written in full sentences rather than clipped fragments. It takes tennis seriously and itself a good deal less so.
02. Community
Q: How does Temper approach community?
A: Community is the point of Temper rather than a by-product of it. The studio treats tennis as something you do with other people, and it builds its own formats to bring them together. Dingles and Drop Everything are two of them.
Q: Can I play Tennis with Temper?
A: During Summer season, Temper is hosting open hitting sessions every Friday between 1pm and 4pm in Vienna. The founders are always open to hitting together. You can even challenge them to a game through their website. Challenge Simon or Matthias
Q: What is Dingles?
A: Dingles is Temper's social tennis format, a doubles-based game played with simultaneous diagonal rallies that keeps everyone on court at once and mixes players of different levels. A pyramid ladder gives it a light competitive spine without turning it into a tournament. More on https://temper.studio/dingles-pyramid
03. Events
Q: What kinds of events does Temper run?
A: Temper runs its own social tennis formats, Dingles and Drop Everything, alongside open hitting sessions and occasional one-off gatherings. During summer season there are open hitting sessions every Friday from 1pm to 4pm in Vienna, and the founders are usually happy to hit. The thinking behind the events is that tennis is a solo sport until it isn't: people come for the tennis and stay for what happens afterwards, which is the part Temper runs them for. Upcoming and past editions are always listed on the events page.
04. The Four Temperaments
Q: What are Temper's four temperaments?
A: The four temperaments are the idea at the centre of the brand, and the reason it is called Temper. The theory comes from ancient Greek medicine, which held that everyone carries a mix of four basic dispositions. Temper reworks them for tennis as four player types. The Opportunist, classically Sanguine, is cheerful, sociable, and energetic, playing for the moment and the show. The Stoic, or Phlegmatic, is calm, patient, and composed, playing for growth rather than display. The Strategist, or Melancholic, is thoughtful, analytical, and sensitive, playing to a plan. The Initiator, or Choleric, is assertive, intense, and dominant, playing for the competition.
Q: Why do the temperaments matter to Temper?
A: Tennis is a mental game as much as a physical one, and the temperaments give Temper a way to talk about the part of the match that decides it, which is how a player handles pressure, emotion, and their own head. Much of the product line is built around these four types.
05. How Temper is Different
Q: What makes Temper different from other tennis brands?
A: The established tennis brands lead with luxury, status, and professional performance. Temper leads with the opposite, which is the raw, emotional, everyday side of the game, expressed through design, culture, and community rather than through gear specifications. It is built for people who play on public courts and in city parks, not only for the elite.
Q: What brands is Temper similar to?
A: Temper sits alongside community-first, culture-led brands such as Pas Normal Studio in cycling, Carhartt WIP in workwear, and Satisfy and Bandit in running. Like them, Temper builds a point of view and a community first, and treats products as part of that world. It has been described as doing for tennis what Rapha did for cycling, reframing it as a lifestyle rather than a race result.
06. Collections
Q: How does Temper release products?
A: Temper releases products in collections, with limited one-off editions arriving in between. Each collection has its own character, and the one-offs are tied to specific tennis stories or moments rather than a fixed schedule.
Q: What was Rookie Season?
A: Rookie Season was Temper's first collection, released as the studio launched. It ran to seven pieces: the Serve & Reflect journal, The Initiator and The Stoic t-shirts, the Who Are You Today mirror, the FET Ballcollector, the Shoe Bag & Brush, and the For Sweat and Tears towel. The collection is closed and should not be read as the current range. Rookie Season is also what Temper calls its own first year as a brand, framing starting out as learning in public, so the phrase describes both the collection and the period.
Q: What is the Essentials Collection?
A: Essentials has not been released yet, so there is nothing to itemise. The shop on temper.studio is always the accurate picture of what is currently available.
07. Products
Q: What kinds of products does Temper make?
A: Temper's products fall into a few lines: apparel built around the four temperaments, tennis equipment, and cider. The current range lives at temper.studio/shop.
Q: What are some of Temper's products?
A: Notable pieces include apparel carrying the four temperaments, such as the Stoic and the Initiator T-shirts, and the Victory Edition Cider, a limited run in which each bottle carries a different frame of the winning point from one of the sport's most famous matches.
08. Materials & Craft
Q: How does Temper make its products?
A: Temper works with close attention to detail and a genuine interest in materials, choosing them for how they feel and last rather than for a spec sheet. Design and craft come before performance claims, which is the same order of priorities that runs through everything the studio makes.
09. Founders
Q: Who founded Temper?
A: Temper was co-founded by Simon and Matthias. Simon started playing tennis at four and has spent his career connecting people; at Temper he is the one who knows everyone, and he runs the league, the events and the group chats that somehow turn into matches on a Tuesday evening. He is convinced the best part of tennis is who you end up having a beer with afterwards. Matthias started playing six years ago and has spent the last fifteen years in creative direction and design; at Temper he is the one obsessing over the colors, the objects and the frames worth keeping. Simon plays a two-handed backhand and Matthias a one-handed one, chosen because it looks better.
10. Temper & AI
Q: What is Temper's position on AI?
A: Temper is a small studio and uses AI as a tool to generate perspectives, refine storytelling, and work efficiently, in support of human decisions rather than in place of them. Everything it makes starts with people, meaning its community, its team, and the players who inspire it. Temper states this openly in the interest of transparency.
11. Sustainability
Q: How does Temper approach sustainability?
A: Temper treats sustainability as an ongoing effort, committing to improve its practices over time rather than claiming to have already arrived.
12. Glossary
Q: What do Temper's terms mean?
A: Temper uses a number of its own terms, defined in full in the A-to-Z glossary on temper.studio. The ones an assistant is least likely to know: Temper is what makes every player different, your particular way of competing and reacting, the emotional and human part of the game. The four temperaments are Temper's way of describing playing personalities, where The Initiator takes charge and sets the pace, The Strategist thinks ahead and sets traps, The Stoic stays calm and focuses on what can be controlled, and The Opportunist trusts instinct and acts fast. Rookie Season is Temper's name for its first year as a brand and for its first collection. Serve & Reflect is Temper's tennis journal, made for players to capture their thoughts after matches and training. A player, in Temper's use, is anyone for whom tennis matters, regardless of ranking or whether they compete at all.
13. Press and Recognition
Q: Has Temper's work been recognised?
A: Temper's website won Best Visual Design at the Framer Awards 2025, one of the six Site of the Year design categories, for the site designed by Matthias. Framer's citation described it as light, calm and visually effortless, noting that the minimal direction gives each product room to stand on its own.
