Wearable Skincare Fabric for Deeper and Better Sleep

🧬 What Makes SeaCell™ So Special?

SeaCell™ is a bio-based fiber made by blending Icelandic seaweed with eucalyptus-derived modal. This isn’t just soft, it’s smart — bringing natural antioxidants, minerals, and skin-calming properties to your everyday wear.

🌊 Key Benefits:

• Rich in Antioxidants: SeaCell™ retains vitamin E, calcium, and magnesium, which interact gently with your skin.
• Thermal Regulating: Keeps you cool when it’s warm, warm when it’s cool.
• Breathable & Moisture-Wicking: Outperforms cotton and synthetics in airflow and dryness.
• Naturally Antibacterial & Hypoallergenic: Great for sensitive skin or hot climates.
• Sustainable & Closed-Loop: Uses minimal water and no toxic solvents. Fully biodegradable.

Think of it as skincare you wear.

🌿 A Daily Uniform for Deep Recovery

At Greyte, we believe comfort should never be compartmentalised. That’s why we designed a collection of SeaCell™ essentials — the same t-shirts can be for the day & pajamas for the night — all made with the same revolutionary, skin-loving fabric.

Whether you’re commuting, creating, lounging, or sleeping — these garments are made to move with you, breathe with you, and restore you.

One Fabulous Fabric. Two Wearable Forms. Zero Compromises.

Greyte care about women’s comfort 

Too many women’s t-shirts force you to choose between comfort and support—either you wear an extra bra that digs and pinches, or you skip it and sacrifice shape, lift, and confidence. Greyte Shirt ends that compromise. With its built-in bra and perfectly placed shirt padding, it gives you the natural support you need and the all-day comfort you’ve been craving—so you can look effortlessly put-together while feeling completely free.

👤 10 Reasons this is the Best Pajamas Ever 

1. Sleep-Enhancing Cool Comfort – Greyte pajamas help you fall asleep faster, sleep deeper, and wake more refreshed by keeping you comfortably cool. SeaCell™ fabric naturally breathes and dissipates excess heat, preventing the too-warm discomfort that can keep your mind alert. A cooler sleep environment signals your body to increase melatonin production — the hormone that regulates your sleep cycle — while helping lower cortisol, the stress hormone that can delay rest. The result is a calmer mind, a more relaxed body, and a smoother transition into deep, restorative sleep.

2. Luxury You Can Feel – Greyte pajamas aren’t just soft — they’re sensorially indulgent. SeaCell™ ‘s made from natural seaweed and eucalyptus with ultra-fine fibers glide smoothly across the skin, reducing friction and irritation. The fabric’s natural drape creates a weightless, enveloping feel, while its silky finish adds a touch of quiet luxury you’ll notice every time you slip them on. It’s comfort elevated to an art form.

3. Skin-Nourishing Care – Greyte pajamas go beyond comfort by caring for your skin as you wear them. SeaCell fibers are embedded with nutrients from seaweed, such as calcium, magnesium, and antioxidants, which are released upon contact with moisture from your skin. Greyte is the skincare you can wear. 

4. Breathable Temperature Regulation – Greyte pajamas keep your body in its comfort zone all night long. The SeaCell™ fabric allows air to flow freely, releasing excess heat when you’re warm and trapping just enough warmth when the air gets cool. This natural thermoregulation helps maintain an ideal microclimate around your skin, preventing the overheating or chill that can disrupt sleep. By keeping your temperature steady, your body can focus on deeper, uninterrupted rest.

5. Moisture-Wicking Freshness – Greyte pajamas actively pull moisture away from your skin, keeping you dry and comfortable throughout the night. The SeaCell™ fabric’s natural fibers absorb sweat and release it quickly into the air, preventing dampness and stickiness that can cause discomfort or disrupt sleep. This moisture management not only helps maintain a fresh feel but also reduces the risk of skin irritation, so you can rest easy feeling clean and cool.

6. Comfort Without Boundaries – Greyte pajamas are designed to move seamlessly with you throughout your entire day and night. Made from the versatile SeaCell™ fabric, they effortlessly transition from morning activities to evening relaxation without needing to change. Minimalist design that works for Zoom calls, coffee runs, couch time, travel or sleep — no wardrobe changes needed.

7. Lightweight Strength – Greyte pajamas combine the best of both worlds: featherlight comfort and durable construction. The SeaCell™ fabric is finely woven to feel airy and soft against your skin, yet engineered to withstand daily wear, frequent washing, and long-lasting use. This balance ensures your pajamas stay intact and look fresh without feeling heavy or restrictive—giving you lasting comfort that keeps up with your lifestyle.

8. Freedom to Move – Greyte pajamas are crafted to support your body’s natural motion without restriction. The SeaCell™ fabric offers gentle stretch and flexibility that adapts to every twist, stretch, and turn, whether you’re lounging, sleeping, or on the go. This dynamic fit ensures you stay comfortable and unrestricted, making it easy to move freely throughout your day and night.

9. Earth-Friendly Craftsmanship – Greyte pajamas are thoughtfully made with sustainability at their core. The SeaCell™ fabric is derived from renewable seaweed and sustainably sourced fibers, produced using low-impact, eco-conscious processes that minimize waste and reduce environmental harm. Every step—from material harvesting to manufacturing—is designed to honor the planet, so you can enjoy luxurious comfort with a clear conscience.

10. Smart Designs – Greyte pajamas are crafted with thoughtful details that prioritize your comfort and ease. The women’s t-shirt features a built-in bra top, providing gentle support so you can move freely and comfortably without needing extra layers. The adjustable tie waistband lets you customize the fit to your liking—whether loose and relaxed or snug and secure. And, naturally, practical pockets are included to keep your essentials within easy reach, combining style, function, and comfort seamlessly.

👤 How It All Began: From Burnout to Breakthrough

The idea for Greyte came not from a fashion showroom or fabric lab — but from a moment of exhaustion.

Rotating between stiff office clothes by day and threadbare tees or synthetic loungewear by night. I had invested in performance shoes, ergonomic chairs, cold-pressed juices — but somehow, what I wore for the 8 hours a night I was supposed to recover was an afterthought.

Then came the realization:

“If we spend a third of our lives sleeping, why are we still sleeping in clothes that do nothing for us?”

That insight stayed with me.

The idea wasn’t just to make another pajama set — it was to design a system of clothing that supports your body in both rest and motion, crafted from materials that nourish the skin, breathe naturally, and feel incredible.
