The THETA 2026 range splits into three collections: the Race Collection is stripped-back race-day kit built to disappear once the gun goes, the Training Collection is durable daily-training pieces tested over two race seasons, and the Complete Collection bundles every piece as one hybrid-athlete system at 20% off. Which you choose depends on whether you are chasing a race-day marginal gain, kitting out for weekly training, or buying the full wardrobe in one go.

• All three collections share the same fabric philosophy: ultra-light polyester and polyester/elastane, laser-cut or woven ventilation, and reinforced high-stress seams.
• The 2026 range was tested for over 20,000 hours by THETA's Elite 15 athletes across 2 full race seasons.
• The Training and Complete collections carry a 20% bundle discount as of 2026; check the product pages for current pricing.

What is the Race Collection built for?

Picture the last 200 metres of a race, soaked through, and a singlet you have not thought about once. That is the Race Collection: a stripped-back race-day system of the Race Singlet and Race Short, plus the women's Race Singlet and Race Short. It uses ultra-light polyester/elastane with laser-cut ventilation holes and heat-sealed construction, with storage only where it genuinely matters on race day. The reinforced shoulder and hem seams sit exactly where light race kit tends to fail first, so the weight comes off without the durability going with it.

The design principle is kit you forget once the start gun goes. Over 8 kilometres of running and 8 stations in a hot indoor arena, the singlet is engineered to stay out of your way, and the women's Race Short holds a clean silhouette under intensity rather than losing shape like loose run shorts. This is the collection for athletes optimising the race itself.

What is the Training Collection built for?

Think of the top drenched in the corner of your gym bag on a Tuesday, back out again on Thursday. That is the Training Collection: the core of daily HYROX preparation, built from the Tech Short v2, the Tech T-Shirt Race Team v2, and the Tech Tank in Race Team and THETA Graphic versions. These pieces are built around the failure points that HYROX training exposes, sketchy zips, bouncing pockets, seams that give out on sleds and racks, and they are cut to keep working through repeated high-output sessions, runs, sleds and lunges.

The Tech Short v2 uses durable polyester/elastane with 4-way stretch and flat side pockets, while the Tech T-Shirt Race Team v2 went through more than 20 fabric and fit revisions to stop it clinging when soaked. Everything here was tested for 2 years by the record-setting race team, which is why the Training Collection is the sensible starting point for most athletes.

How do the three collections compare?

Lay all three out on a bench and the choice sorts itself by primary use. If your priority is race day, start with the Race Collection. If your priority is showing up week after week, start with the Training Collection. If you want the full system and the best per-piece value, the Complete Collection covers everything at a discount.

"Most people should start in the Training Collection, because that is what you live in five or six days a week. The Race Collection is the sharp end, the kit you save for the day it counts. If you know you want all of it, the Complete Collection just makes the maths easier," says the THETA coaching team.

How was the 2026 range developed?

Every collection comes back to a prototype pulled on in a training hall and picked apart afterwards. The race team wears prototypes in real HYROX training and races, then feeds back on anything that gets in the way when they are deep into an effort, and the piece is revised. The Tech T-Shirt v2 alone went through more than 20 fabric and fit revisions before it was signed off, which is the level of iteration behind the whole 2026 line.

That process is why the range shares a consistent vocabulary: laser-cut ventilation, woven-in breathable holes, heat-sealed zip pockets, fused and reinforced seams, and a fitted-chest, relaxed-stomach cut. The coaches and athletes behind the range sit behind 12 world records and have logged over 20,000 testing hours, so the kit is developed as tooling for racing rather than styled for a catalogue.

Which collection should you buy first?

Come back to that soaked singlet at the finish line, and the order of decisions falls into place around one question: what is next for you?

1. If you have a race booked in the next block, prioritise one Race Collection top and short.
2. If you are building or maintaining weekly training, start with the Training Collection.
3. If you want both and value convenience, the Complete Collection covers everything at 20% off.
4. Unsure of size? Read the fitted-chest, relaxed-stomach fit notes before ordering.
5. Check the current product pages for pricing and available colours, which change across 2026.

Common questions

What is the difference between the Race and Training collections?

The Race Collection is stripped-back race-day kit, the Race Singlet and Race Short, built ultra-light with laser-cut ventilation to disappear during competition. The Training Collection is durable daily-training kit like the Tech Short v2 and Tech T-Shirt v2, built to survive repeated sleds, lunges and washes. Race kit optimises one day, training kit optimises the whole block.

Is the Complete Collection cheaper than buying pieces separately?

Yes. The Complete Collection bundles every piece at 20% off as of 2026, which gives the lowest per-piece cost if you want the full system. Buying individual items is more flexible if you only need one or two pieces. Check the current product page for exact pricing.

Which THETA collection is best for beginners?

Most beginners should start with the Training Collection, because it covers the kit you wear for the majority of your sessions and is built for durability through repeated high-output work. Add a Race Collection piece when you have a race booked. This keeps your first purchase focused on where you spend most of your time.

Can you race in the Training Collection?

Yes. The Tech Short v2 and Tech T-Shirt Race Team v2 are lightweight, Elite 15-tested pieces that many athletes race in comfortably. The dedicated Race Collection simply strips things back further for a pure race-day fit and feel. Either works for competition, so the choice comes down to how minimal you want your race kit.

What do all three collections have in common?

They share THETA's core fabric system: ultra-light polyester and polyester/elastane, laser-cut or woven ventilation, reinforced high-stress seams and a fitted-chest, relaxed-stomach cut. All were developed through the same athlete-led design loop and tested across two race seasons. The difference is how stripped-back or storage-heavy each piece is for its purpose.

Does the 2026 range come in women's fits?

Yes. The Race Collection includes a women's Race Singlet and women's Race Short, engineered by THETA's female athletes with a women's-specific cut, laser-cut ventilation and structure that holds shape under intensity. The training pieces also come in cuts suited to female athletes. Check individual product pages for the women's options available in 2026.
