Yes. The ORUUN Running Tee is designed for running in hot and humid conditions. Its lightweight technical construction and moisture-management performance help reduce the heavy, clingy feeling that can develop as heat and sweat build.

The ORUUN Running Tee uses LEVANTE ECO GRS PFP fabric from MITI Spa in Italy. Made from 95% polyester and 5% elastane, the fabric uses post-consumer recycled polyester and was selected for its low weight, soft feel and moisture-management performance during warm-weather running.

What types of running is the ORUUN Running Tee designed for?

The ORUUN Running Tee is designed for daily training, long runs, tempo sessions and warm-weather running. Its balance of coverage, low weight and moisture management makes it a versatile option for regular and higher-output training.

What is ORUUN DRY FLOW™?

DRY FLOW™ is ORUUN’s performance approach for running in warm, humid and high-sweat conditions. In the Running Tee, it combines lightweight technical fabric, moisture management and low-distraction construction to support comfort as heat and sweat build.

Nicely judged fabric

The material feels fine and smooth rather than papery. I like that ORUUN has paired it with a design that doesn't look like standard teamwear.

My new favourite colours

Aqua into purple. Yes please.

Good across the upper back

No tight line between my shoulders when I stretch forward. That matters more to me than having the closest possible fit.

Better on the muggy days

The days when the air barely moves are when I notice this tee most. Sweat doesn't make it feel bulky around my torso, and a bit of breeze makes it nicer still.

The shirt outlasted my enthusiasm

Planned a long outing, turned back early. Still impressed by how airy the tee felt on the climb home.

Aqua and purple works

Wasn't sure from the name alone, but the aqua upper and purple detail look lovely together. Quite different from everything else in my drawer.

I don't speak fabric

Can't tell you anything clever about yarns. I can tell you I didn't spend the run peeling it off my tummy.

The cooldown test

Some shirts are fine at speed and horrible when you stop. This remained comfortable while I walked out my cooldown, even with sweat across my back. That's a part of training I think kit descriptions often miss.

Beautiful, slightly boxy on me

Colour and fabric quality are gorgeous. The cut runs a bit boxy on a smaller frame — I'm 5'4"/52kg and would size down if XS were stocked. Still wearing it nearly daily.

Purple that doesn't read 'purple shirt guy'

Wanted a purple running tee but didn't want to look like a 2015 marketing meme. The blue side panels break it up enough that it reads as design rather than statement. Drape reminds me of On's lighter performance pieces — comparable feel, way better price after the AU exchange.

More running, less readjusting

I bought it because I was tired of stopping to sort my shirt out. Didn't expect a miracle, just fewer little interruptions. On my usual loop I adjusted the hem once at the start and pretty much left it alone after that. The material still touched my skin when wet, but it wasn't the sticky, dragging contact that bothers me in thicker tops.

For my first club session

Was more worried about remembering everyone's names than about the shirt. Comfortable sleeves and a nice amount of stretch during the warm up.

Not saving it for races

Wore it to jog to the post office. Technical enough for a session, comfortable enough for the unglamorous errands too.

A bit of colour after work

Most days I go straight from a desk to a short jog. Pulling this on helps with the transition more than another grey shirt would. The blue, purple and dark lower section are a nice combination. It also feels soft enough that I don't rush to change as soon as I finish walking home.

Track bag regular

Low bulk, soft fabric, no obvious pulling through the shoulders during strides. A sensible training tee with a less predictable design.

25k long run, no chafe anywhere

My marathon training tee. Did a 25k yesterday and not a single hot spot — not under the arms, not at the collarbone where some performance tees rub me raw. The slightly relaxed cut means it doesn't lock onto your skin when you sweat. Will be my race-day tee in May.

Hot yoga approved

Wore it to Bikram (40°C, 90% humidity). Came out drenched obviously, but the fabric never stuck or felt heavy. That's a real test.

Goes from yoga studio to morning run

I'm a yoga-and-run girl and most performance tees feel too sporty for the studio. The purple + blue panel combo on this one straddles the line perfectly — looks designer enough to wear into Power Living, technical enough to actually run a tempo in. Stays put in downward dog, no riding up.

Quality you can feel

I'm picky about athletic wear at 41. Stitching is clean, fabric has weight without being heavy, colour is exactly as pictured. The blue side panels are a smart way to hide sweat marks during HIIT class.

My wife stole this one

I bought it. She wears it. The purple looks better on her anyway. Going to order another for myself and call it a household win.
