Improving comfort and function for people living with Raynaud’s syndrome.

Learn what Raynaud’s syndrome is, why it matters, and how we are developing medically aligned heated technology to improve daily comfort and quality of life.

What Is Raynaud’s Syndrome?

Raynaud’s syndrome is a condition that affects blood circulation, especially in the fingers and toes. When someone with Raynaud’s is exposed to cold temperatures or stress, the small blood vessels in these areas tighten more than usual. This reduces blood flow and can cause the skin to change colour, feel very cold, numb, or painful.

Common Triggers & Symptoms

Triggers may include:

Cold weather or cold indoor environments

Holding cold objects (steering wheel, drinks, door handles)

Stress or sudden emotional shifts

Rapid temperature changes

Typical symptoms:

Fingers or toes turning white, blue, then red

Cold, numb, or “dead-feeling” fingers

Tingling, throbbing, or pain when circulation returns

Difficulty using hands during attacks

Impact on Daily Life

For many people, Raynaud’s is more than just discomfort; it can disrupt everyday tasks such as typing, driving, opening items, cooking, working outdoors, or simply spending time outside in colder seasons. Even mild environments like air-conditioned offices or grocery stores can trigger episodes.

The Gap in Current Solutions

People living with Raynaud’s often turn to products that provide some relief for a short amount of time; most existing options were not created with this condition in mind. They are not reliable or practical for everyday use.

Common challenges with current solutions include:

Disposable hand warmers: Provide temporary warmth, but the heat can be inconsistent, difficult to control, and only lasts for a limited time.

Standard winter gloves: Offer insulation, but do not actively generate heat; warmth relies only on the user’s own body temperature, which is often not enough during a Raynaud’s episode.

Lack of Raynaud's focused design: Most products are not developed specifically for people with cold-sensitive circulation issues, resulting in solutions that are helpful but not truly tailored to their needs.

Our Innovation & Approach

We are developing a medically aligned, patent-pending warming solution designed specifically for people with cold-sensitive circulation challenges. Our gloves combine controlled heating, technical materials, and ergonomic design to provide consistent warmth and comfort in daily life, both indoors and outdoors.

What our gloves offer:

Consistent and controlled warming for reliable comfort

Freedom of movement and dexterity to support everyday tasks

Long-lasting performance through rechargeable power

Thoughtful design focused on usability, durability, and fit

Developed with medical needs in mind, not just for outdoor use

Important: Our product is not a medical treatment or cure, and does not replace clinical care. It is being developed as a supportive, comfort-focused solution.

Customer reviews

“Walking my dog in the winter used to be a struggle, and I often had to ask someone else to do it. Now I can join our daily walks again, even when it’s cold outside. It feels amazing to enjoy that time outdoors without constantly worrying about my hands.”

Laura, 55

“For years, winter driving was something I avoided because my hands would get painfully cold on the steering wheel. With these gloves, I finally feel comfortable enough to drive again, even on chilly mornings. It’s given me a part of my independence back.”

Anna, 74
