Eira Coffee

Eira Coffee

Nordic Whisper- ZQ Fine Marino, Brushtail Possum and Mulberry silk.

The EIRA sweater embodies quiet elegance — a sculpted symphony of warmth and refinement. Its ivory hue evokes the serenity of winter light, while the linear Jacquard motif across the front reflects the geometry of Northern artistry. Feather-soft against the skin, EIRA speaks not of extravagance, but of cultivated restraint — a timeless signature for those who understand the beauty of understatement.

Each EIRA is whole-garment engineered using seamless technology, resulting in a seamless silhouette that drapes flawlessly without stitch interruptions. The subtle patterning on the front panel is knitted in structural relief — an intricate dance of precision and purity. Designed for elite comfort and quiet confidence, it transitions effortlessly from alpine retreat to metropolitan atelier.

Engineered by Nature, Perfected by Brrotank

Our ZQ-certified Merino wool is ultra-fine at just 19.5 microns-light on the skin but made to endure. Spun in Italy and fortified with our proprietary Eternity X-Care® finish, it’s elegance crafted to stand the test of time.

Hot or cold, indoors or out-this wool adapts. The natural crimp of Merino creates breathable air pockets that trap warmth or release it as needed. It's nature’s way of regulating temperature-no adjustment required.

Naturally antibacterial by design, our wool inhibits odour and resists bacteria build-up. That means fewer washes, longer life, and an easier relationship with your wardrobe.

Brrotank Merino absorbs up to 30% of its own weight in moisture while staying dry to the touch. Whether you’re layering up or moving through climates, it keeps you dry, fresh, and comfortable.

Crafted using advanced seamless knitting technology, each Brrotank garment is made in a single flow - no stitching, no panels, no waste. It’s not assembled, it’s engineered. The result? Smoother fit, longer durability, and a garment as pure as the yarn it’s made from.

🌿 Second Skin Comfort
Luxury You Can Live In.

Wash Care Guide
Caring for your knitwear ensures it lasts a lifetime - naturally soft, seamless, and performance-rich. Our garments are made from rare natural yarns and deserve gentle, thoughtful care.
🖐️Hand Wash Preferred
Wash your knitwear gently by hand in cold water. Use a mild, wool-friendly detergent. Do not wring, twist, or rub the garment - just press out the water gently.
🌀Machine Wash
If hand washing isn’t possible, use your machine’s wool or delicate cycle with cold water. Place the garment inside a mesh laundry bag for added protection.
🧴No Harsh Additives
Avoid fabric softeners, bleach, or enzyme-based detergents. These damage natural fibers and affect longevity.
🪵Dry It Flat
Never hang your knitwear to dry - it can stretch. Instead, lay flat on a towel away from direct sunlight or heat. Gently reshape while damp
🧳Store with Care
Fold your knitwear instead of hanging. Store it in a cool, dry place. Use a breathable fabric bag or storage box with lavender or cedar to keep moths away.
♻️ Minimal Washing, Maximum Longevity
Thanks to Merino and Possum’s natural odor-resistance and breathability, you don’t need to wash after every wear. Air your garment between uses - it’ll stay fresh.
