How it Works
-
How it Works
Why It Matters: Sleep quality isn’t just about hours in bed, it’s about time spent in recovery mode. When temperature or comfort are disrupted, the body slips into the sympathetic “fight or flight” state, leading to fragmented sleep & reduced recovery.
How It Works: Our sleepwear is designed to maintain thermal stability & optimise sensory comfort through the night. This reduces arousal triggers & supports maximal parasympathetic recovery.

“Hormonal changes across the menstrual cycle and menopause can bring symptoms that disrupt sleep, often through altered temperature regulation and night-time discomfort. Zed integrates fabric choices that support thermal comfort and reduce sensory disturbance, reflecting an evidence-led approach grounded in sleep physiology and scientific testing.”

"My journey with Ben explored all aspects of creating sleepwear that truly delivers under the varied circumstances we all experience. With the elite athletes I coach trying to achieve sustainable, optimal performance by optimising recovery, it's all about familiarisation. Zed's science-led fabric uses soft touch and temperature regulation that make it part of any professional pre-sleep routine."

"Thermal comfort is one of the key physiological factors linked to faster sleep onset and fewer night-time awakenings. Zed’s focus on natural fibres and thoughtful garment design reflects these principles, creating sleepwear that helps maintain the stable conditions the brain and body need for restorative sleep."
Nina Kapp
Sleep Therapist & Human Performance Specialist
"What immediately stood out to me about Zed was the feeling of deep physical ease combined with a subtle sense of support. The garment creates a cocoon-like feeling of comfort without restriction, allowing the body to relax while maintaining complete freedom of movement.
The fit is genuinely unique. Rather than asking the wearer to adapt to the garment, the garment adapts to the wearer. The fabric, construction and thoughtful design details work together to create a feeling of effortless comfort throughout the night.
To me, this is where Zed stands apart. Every detail feels deeply considered, creating the trust, ease and comfort that allow the body to fully let go."
ZedCore™ technology, engineered for uninterrupted sleep
Crafted with ultra-soft natural fibres derived from beechwood, ZedCore™ was designed with six advanced pillars of comfort. To keep you at your perfect temperature and reduce the small irritations that can interrupt quality rest.

During REM sleep your body’s ability to regulate temperature is impaired. Our Sleepwear contains a nanostructure that naturally dissipates heat & moisture, helping you keep the perfect temperature throughout the night.

Holds moisture

Overheating and night sweats can disrupt your sleep cycles, preventing you from reaching the most restorative stages of rest.
The nanostructure of our advanced fabrics uses a dual cooling functionality that pulls moisture away from your body quickly & moves it to the fabric exterior for evaporation.

Can feel coarse

During sleep, blood flow to your skin increases as our cells regenerate, making it more sensitive to touch. Our super fine fibre structure, developed with Micro technology means our garments deliver a barely-there sensation.

Prolonged wear can lead to odours that disrupts the feeling of freshness, impacting the quality of your sleep environment. Our naturally odour-resistant fibres prevent the build-up of bacteria. No more frequent washing, just lasting freshness.
How ZedCore™ compares
Most sleepwear fabrics are not designed for sleep. ZedCore™ perfectly balances softness, breathability, moisture control and freshness through the night.
Cotton is soft and familiar, but it can trap heat, hold moisture and feel heavier when damp. ZedCore™ is designed to keep you cool and dry, whilst still feeling weightless throughout the night.
Compared with cotton
- 2× softer
- 12× more breathable
- 4× better sweat management
- 10× less bacteria growth

From professional athletes to hot sleepers. Zed is designed for anyone who wants to sleep cooler, deeper and more comfortably.

“I’ve tried a lot of health & performance products over the years, but Zed genuinely stands out. It’s by far the most comfortable sleepwear I’ve worn, you barely notice it when it’s on. It helps keep my body temperature steady overnight, which is key for quality sleep, and just as importantly it looks and feels genuinely premium.”

Same soft, breathable fabric as the t-shirt and just as comfortable for warm nights. Sized down to a small (I’m a UK size 8/10), on the company’s advice and it was the right call — great fit, not too loose, not restrictive. Well made, easy to see these lasting. Highly recommend, and they’re on my gift list for friends too.

I only really wear sleep masks on planes so, given it's just a few nights per year, I just use one of the freebies that I got and kept. This is so much better on a few levels (mostly comfort, but also durability and better at keeping out light too). I wish I had it sooner!

Incredibly soft and lightweight, genuinely breathable enough to sleep in through a Dubai summer, which is the real test for any sleepwear here. I sized down to a small on the brand’s own recommendation (I’m usually a UK 8/10) and the fit is spot on, relaxed without being baggy. Quality feels premium, holds its shape after washing. Already planning to buy more as gifts.
