Merino Short - 5"
Designed for everyday movement in merino.
Shop nowWhy Most Merino Activewear Looks Boring — And Why Estroni Is Different
For years, women looking for merino activewear had only two options:
- Hiking base layers designed for cold weather
- Shapeless outdoor tops made for unisex fit
Great for trekking. Not great for the gym, everyday wear, summer heat — or feeling confident.
Estroni exists to change that. We design merino pieces that flatter, breathe, move, and actually look good.
1. Why Most Merino Activewear Fails Women
Traditional merino apparel brands design for utility, not body shape or aesthetic fit.
Common issues with “standard” merino:
- Boxy cuts that hide shape instead of flattering it
- Heavy knits built for winter, not movement or heat
- Low-stretch 100% merino that sags or bags out
- Unisex fit → poor shoulder fit, gaping armholes, drooping waist
- Hiking-first design instead of gym, yoga, Pilates, or lifestyle
No wonder so many women on Reddit say:
“Why does all merino clothing look like hiking gear?”
2. The Estroni Difference: Merino Designed for Women’s Bodies
Estroni pieces are engineered from the ground up for women’s proportions, curves, and movement patterns — not repurposed from outdoor gear.
What this means:
- Waist sculpting that holds shape without compression discomfort
- Hip and glute contouring → leggings that flatter, not flatten
- No side seam twisting thanks to fabric recovery
- Shoulder and armhole geometry tailored for women
- Sleek silhouettes that feel elevated, not outdoorsy
3. Designed for Summer — Not Just Winter
This is where Estroni truly breaks the mold.
Most brands design merino as:
- thermal layers
- midweight sweaters
- winter-only performance knits
Estroni builds merino for +30°C outdoor training, hot yoga, coastal runs, and Australian summer heat.
How?
- 17.5–18.5 micron yarn → lightweight, airy, cool
- Moisture buffering → absorbs sweat vapor, not liquid saturation
- Open-knit airflow without transparency
- Thermoregulatory cooling (why sheep thrive in 40°C heat)
No other merino activewear brand optimises for hot-weather comfort the way Estroni does.

4. Why 95/5 Makes the Fit Perfect
We deliberately use a 95% merino / 5% elastane blend — not for cost-cutting, but because this is the optimal ratio for stretch, shape, and durability.
Compared to 100% merino:
- Estroni leggings keep their shape all day
- No sagging at knees or waistband
- No bagging after squats or running
- Dramatically fewer pinholes
- Better fit in bra bands and straps

5. Ultra-Soft Against Skin (Micron Matters)
Estroni uses 17.5–18.5 micron Australian & NZ merino — below the itch threshold for most people.
This matters because:
- Microns = softness (not brand marketing)
- Lower microns bend against the skin instead of poking it
- High-movement activewear demands next-to-skin comfort
6. Naturally Odor-Resistant — Perfect for Activewear
Merino wool neutralises odor-causing bacteria thanks to:
- Keratin fibre structure
- Lanolin’s antimicrobial properties
- Internal moisture absorption
This means:
- Your leggings stay fresh far longer than synthetics
- You wash less → better durability
- No “gym smell” after workouts
7. Why Estroni Is the First True “Fashion Merino Activewear” Brand
Estroni merges natural fibre performance with modern aesthetic cuts.
You get:
- Merino leggings that flatter your waist and hips
- Bras designed for natural fibre breathability
- Tank tops that look elevated, not outdoorsy
- Pieces you can wear all year — hot or cold weather
We’re not making base layers. We’re making natural fibre fashion-performance apparel.
