Sleep Experts
Dr. Bryna Chrismas, PhD
Applied Exercise Physiologist & Accredited Exercise Scientist
“In female athletes, sleep underpins recovery, training adaptation, and long-term wellbeing. Temperature regulation is a core component of sleep physiology and becomes particularly relevant across different life stages, including when menstrual cycle–related or hormonal symptoms disrupt sleep. Zed Sleep’s commitment to designing around these mechanisms and investing in rigorous scientific testing demonstrates a clear focus on evidence-led innovation in support of athlete health and performance.”
Nick Littlehales
Elite Sports Sleep Coach
"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."
Anne-Sophie Fluri, MRes
Neuroscientist
"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."

“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.”
Kate Kallaway
Apparel Designer
“With over 20 years of experience in sportswear design, including collaborations with Reebok and Pentland, we’ve created sleepwear that truly performs. We designed Zed with purpose, bringing together human-centred design thinking to support better sleep and overall wellbeing. Every detail is considered, from carefully positioned seams that reduce irritation to advanced fabrics that regulate temperature, maximise comfort and aid recovery."
