FAQ Products BUFF® | BUFF® Canada

Our response to COVID-19

Since the coronavirus pandemic became global, we received many questions regarding the use of our products as an alternative to facemasks against the coronavirus SARS-CoV-2.

Our response was always clear: our already existing multifunctional neckwear products are not scientifically proven to prevent you from contracting or passing the virus to someone else. They are not certified to be used as a replacement to medical grade masks. Wearing a BUFF® product however might remind people around you to maintain a safe and comfortable distance and might remind yourself to not touch your face.

 Our new BUFF® Filter Mask is one of our ways to respond to COVID-19. We have used all our means, expertise and knowledge to create a product designed to face a new situation in the same world we love. The BUFF® Filter Mask has been designed and created in-house by our team and uses replacement filters made in Germany which provide 98% filtration against air-borne particles.

To find out more information about our product certifications, please visit the Certified Quality section on our website. Please read and follow the updates published by the Government of Canada regarding non-medical masks or certified PPE.

    BUFF® mutlifunctional headwear is created through a proprietary knitting process using a special 100% polyester yarn called microfiber, in which the thinness of each filament is less than 1 dtex. The pores on the external surface of the textile become very small to prevent water and wind from passing through the fabric, but simultaneously ensure that the pores on the inside surface are big enough to make the fabric highly breathable.

    Where are BUFF® products made?

    Most BUFF® multifunctional headwear is manufactured in a purpose built factory in Igualada, just outside Barcelona in Spain. Every year millions are sold all over the globe.

    How do I wash my BUFF® headwear?

    For the majority of BUFF® products we recommend that you hand wash in warm water with mild soap. Because of their quick-drying fabric, you can simply lay flat to dry. Do not use fabric softener as it clogs the textile’s pores. Do not dry clean. Do not bleach and only use mild soap. Do not iron.

    Where is the 100% natural merino wool from?

    Australia - Produced using exclusively renewable resources and processes always respectful with the animals to minimize the effects on the ecosystem.

    What is breathability and why is it so important when outdoors?

    Breathable garments have pores that allow the moisture to escape, keeping you comfortable. If moisture is allowed to build up in your clothing, it becomes damp and once you stop moving the dampness draws heat away, causing your body to cool down very quickly. This can be dangerous in cold weather in the outdoors.

    What is “moisture wicking” and why is it so important?

    Moisture wicking relates to synthetic materials that have been developed specifically to channel perspiration away from the skin. Any moisture that can be moved away from the skin will keep you dry and comfortable while active.
