Choose the Race Collection when you want the lightest possible race-day setup with minimal storage, and the Tech line when you want a piece that races well but also handles daily training and carries fuel. Both are built by THETA's record-setting team, but the Race Collection strips weight and features to the essentials while the Tech line keeps pockets and everyday durability.

• The Race Collection is a stripped-back race-day system, Race Singlet plus Race Short, built to disappear once the start gun goes.
• The Tech line, including Tech Short v2 and Tech T-Shirt Race Team v2, is a do-everything system tested 2+ years by the race team.
• Both use ultra-light polyester or elastane fabrics with ventilation and reinforced high-stress seams.

What is the difference between the two ranges?

The Race Collection is made with a single purpose in mind, and everything about its construction reflects that. Ultra-light polyester or elastane, laser-cut ventilation holes placed where heat builds, reinforced shoulder and hem seams set exactly where light race kit fails first, heat-sealed construction, and storage only where it genuinely matters. Nothing is there that the race does not ask for, which is what makes the Race Collection the lightest option on the day. The Tech line is built to a broader brief, worn in daily training and racing alike, so the Tech Short v2 keeps flat side pockets and 4-way stretch, and the Tech T-Shirt Race Team v2 was refined across 20+ revisions. Both race well; the Race Collection simply removes everything the day does not need.

The construction tells you what each was built for

Look closely at how the two are made and the intended use of each becomes obvious before anyone tells you. Take the pockets, because that is where the two ranges most clearly part ways. The Tech Short v2 carries flat side pockets, and the Tech line more broadly is built with heat-sealed zip pockets sized for gels and a phone, seams fused rather than merely stitched so that a loaded pocket does not fray or gape after months of training and washing. That is a decision made for a garment that lives through daily use and carries things, day in and day out.

The Race Collection makes the opposite decision with the same care. Storage exists only where it genuinely matters on race day, and everything else is stripped away, because a pocket you do not need is fabric, weight and a place for something to bounce. The reinforcement follows the same discipline: it is concentrated at the shoulders and hem, the two zones where light race kit fails first under overhead work and the wall-ball squat, and nowhere else. Both ranges share the same philosophy of reinforcing only where the load actually lands, but they answer different questions with it. One is built to survive years of everything. The other is built to survive one all-out race and disappear while it does.

Which is faster on race day?

For a pure time chase, the Race Collection has the edge, and it is worth pausing on why. The Race Singlet exposes more skin and holds less fabric. The Race Short is built to disappear under fatigue. Both are shaped around one idea, that the best race kit is the kit you forget once you start. The gap is small, and the Tech line races at a very high level too, which is exactly why the race team trains and competes in it. If you want the marginal weight saving and do not need pockets, go Race Collection.

Which is better value across the year?

The Tech line usually wins on value because it does more jobs. A Tech Short v2 and Tech T-Shirt v2 will train five days a week, survive sled rash and rack abrasion, carry your keys and phone, and still race on the weekend. The Race Collection is a specialist purchase that earns its place if you race often or chase times, but it sees less use between events. Many athletes own both: Tech for the daily grind and simulations, Race Collection for the events that matter most.

How do you decide for your situation?

Work through it in order:

1. If you race rarely and want one system for everything, choose the Tech line.
2. If you chase times and race often, add the Race Collection for the lightest race-day setup.
3. If you carry gels or a phone during training, the Tech Short v2 pockets matter to you.
4. If you want maximum airflow and minimal fabric on the day, the Race Singlet leads.
5. If budget is the deciding factor, buy the Tech line first because it is used far more often.

"The Race Collection is what we reach for when the clock is everything. The Tech line is what we live in the rest of the time. Most serious racers end up with both for good reason," says the THETA coaching team.

Can you race in the Tech line and train in the Race Collection?

You can race in the Tech line all day, it is built for it, and many athletes never own anything else. Training in the Race Collection is possible but less sensible, because you would take a stripped-back specialist piece into everyday work it was never optimised for, and wear it out sooner. The cleaner split is Tech for training and simulations, Race Collection for the events where the marginal weight saving counts. Both are drawn from the same fabric philosophy, the same reinforced-where-it-must-be thinking, so there is no drop in quality either way.

Let your fuelling plan settle the storage question

The clearest single decider between the two ranges is not weight or value, it is what you carry during the race itself, and most athletes never think it through. HYROX gives you water on course, so the real question is gels. If your race is short enough or your fuelling relaxed enough that you take nothing on the floor and grab what you need in transition, then storage is a feature you would carry for nothing, and the stripped-back Race Collection is the honest choice. If you plan to take a gel or two mid-race and want them secured against bouncing on the runs, you need a flat, secure pocket, and that points to the Tech line.

Work it out before you shop, because it also tells you whether you are choosing a top-and-short system or a single garment. A common and sensible setup is the Race Singlet with a Tech Short for the pocket, mixing the two ranges to get race-day airflow up top and secure storage below. There is no rule that you buy a range whole. The garments share a fabric philosophy, so you can build the exact race system your fuelling plan asks for rather than accepting a compromise in either direction.

Common questions

Is the Race Collection worth it over the Tech line?

If you race often or chase times, yes, because it is the lightest setup with storage only where it matters. If you race rarely, the Tech line races nearly as fast and does far more the rest of the year.

Does the Race Collection have pockets?

It includes storage only where it matters for racing, not the fuller pocket set of the Tech Short v2. If you need to carry gels or a phone during the event or in training, the Tech line is the better fit.

Can I train in the Race Collection?

You can, but it is a race-day specialist and will wear faster in daily use. Training in the Tech line and saving the Race Collection for events is the more efficient approach.

Which top is lightest for racing?

The Race Singlet is the lightest, exposing more skin and holding less fabric. The Tech T-Shirt Race Team v2 is also very light and does not cling when soaked if you want shoulder coverage.

Are both ranges made from the same fabric?

Both use ultra-light polyester or elastane with ventilation and reinforced high-stress seams. The Race Collection strips features to the race-day essentials, while the Tech line keeps pockets and everyday durability.

If I can only buy one, which should it be?

Buy the Tech line first. It trains and races, carries your kit and gets used far more often, giving better value. Add the Race Collection later if you start chasing times.
