Materials & Construction

Materials & Construction

We source our merino wool from ethical farms in Australia, where sheep are raised without mulesing and graze on open pastures year-round. The fiber is naturally renewable, biodegradable, and requires less water than cotton production. After sorting and washing, the wool is spun into a two-ply yarn that balances strength with softness.

Our fully fashioned knitting process shapes each panel to size, eliminating excess fabric and creating a clean, flattering silhouette. The ribbed trim at the neck, cuffs, and hem is knit in a tighter gauge to hold its structure wash after wash. Every seam is linked by hand to lie flat against your body, so there’s no scratching or irritation even during extended wear.


Sizing & Fit

Sizing & Fit

Care Instructions

Care Instructions

Merino wool is naturally self-cleaning and odor-resistant, so you can wear your Helsa Sweater multiple times before washing. When it’s time to refresh, turn the sweater inside out and machine wash on a delicate or wool cycle in cool water with a gentle detergent. Avoid fabric softener, which can coat the fibers and reduce breathability.

After washing, gently reshape the sweater and lay it flat on a clean towel to dry away from direct heat or sunlight. Never wring or tumble dry, as high heat can cause felting and shrinkage. With proper care, the sweater will maintain its shape, softness, and color for years. For seasonal storage, fold (don’t hang) and keep in a breathable cotton bag with a natural moth deterrent like cedar or lavender.

Softer than I expected
I was worried merino would feel scratchy, but this sweater is incredibly soft right out of the box. I've worn it at least twice a week since it arrived, and it still looks brand new. The fit is relaxed but not sloppy — exactly what I wanted.

Perfect weight for layering
I live in San Francisco where the weather changes hourly, and this sweater handles it all. It keeps me warm in the morning fog but never makes me overheat indoors. I ordered a second one in olive after wearing the charcoal nonstop for a month.

Worth every penny
I've bought cheaper sweaters before and they always pill or lose their shape. This one has held up beautifully through multiple washes, and the color hasn't faded at all. The quality is obvious the moment you put it on.

Great for sensitive skin
I usually can't wear wool because it irritates my skin, but merino is a completely different experience. No itching, no redness — just soft, breathable comfort. I wish I'd tried this years ago.

Fits true to size
I'm 5'8" and usually wear a medium. The medium here fits perfectly with enough room to layer a tee underneath. The sleeves are long enough without being too long, and the length hits right at my hips.

Timeless piece I'll wear forever
This isn't a trendy sweater that'll look dated next season — it's a classic you can keep in your closet for decades. The neutral colors work with everything, and the quality means it'll actually last that long.

Helsa Sweater — Your Questions Answered

Yes, the Helsa Sweater is machine washable on a delicate or wool cycle in cool water. We recommend turning it inside out and using a gentle detergent without fabric softener. After washing, reshape the sweater and lay it flat to dry on a clean towel. Avoid high heat, wringing, or tumble drying to preserve the fiber's natural structure and prevent shrinkage.

Merino wool fibers are much finer than traditional wool — around 18 microns in diameter compared to 30+ microns in coarser breeds. This makes merino incredibly soft and breathable against the skin. Our Helsa Sweater uses premium-grade Australian merino that's been tested for comfort, and the vast majority of customers with wool sensitivities report no irritation.

The Helsa Sweater has a relaxed, slightly oversized fit with drop shoulders. We recommend ordering your usual size for a comfortable, lived-in feel. If you prefer a more fitted silhouette, consider sizing down. You can find detailed measurements for each size in the Sizing & Fit section above, or reach out to our team for personalized recommendations.

When cared for properly — washed in cool water on a delicate cycle and laid flat to dry — the Helsa Sweater maintains its original size and shape. High heat and agitation can cause any wool garment to felt and shrink, so we strongly recommend following the care instructions on the label and avoiding the dryer.

Yes, merino wool is naturally temperature-regulating, which means it keeps you warm in cool weather and wicks moisture when it's warmer. The midweight knit of the Helsa Sweater is versatile enough for spring, fall, and winter wear, and many customers layer it over a tee during summer evenings or in air-conditioned spaces.

The Helsa Sweater is currently available in six colorways: Ivory, Charcoal, Navy, Olive, Sand, and Black. Each shade is designed to work as a wardrobe staple, pairing easily with denim, trousers, skirts, and layering pieces. Seasonal colors are introduced twice a year, so sign up for our newsletter if you'd like early access to new releases.

Yes, we source our merino wool from farms in Australia that practice ethical animal husbandry without mulesing. The sweater is produced in a Fair Trade Certified facility where workers receive fair wages and safe conditions.
