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.”

Sleep coach of Cristiano Ronaldo, Manchester United & GB Cycling.
"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."

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."

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

“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.”
