BUKI (boo-key)

Q: What does Buki mean?

A: 'Buki' is the Japanese word for 'protect and defend,' which is in reference to how our proprietary technical fibers function with properties such as thermo-regulation, moisture-management, dynamic stretch & recovery, and more.

FABRIC INNOVATION

Q: What makes Buki fabrics different?

A: Buki tech fabrics utilize state-of-the-art Japanese fiber technology, which is the DNA of all our fabrics. We use the most advanced knitting machine - exclusive to Buki - that plates the fabric together. Fabrics are layered one on top of the other, rather than woven together. Buki tech fabrics offers incredible properties, such as:

Easy Care: Say hello to the washing machine. Bid farewell to the dry-cleaner.
Thermo-regulation: Helps keep your body regulated in its comfort zone.
Moisture-Management: Pulls moisture from your body & transports it far, far away.
Four-Way Stretch & Recovery: Engineered to stretch and move with you, and retain its shape throughout the day.
Anti-Pill: Engineered to resist pilling and stand the test of time
Woven-Like Knit: Structured silhouette looks like a woven, but its actually a knit. (Hello, comfort and Easy Care!)
Quick-Dry: Excellent moisture transportation + wide moisture dispersion = faster drying rate.

PRODUCT CARE

Q: Does Buki need to be dry-cleaned?

A: Buki is engineered for comfort and convenience: our entire collection is machine washable - no need for a dry-cleaner. Enjoy your extra time.

SHIPPING

Q: How fast will my order ship?

A: All orders will be mailed out within 2 business days of being received. We understand the beauty of 'now.' Shipping will be applied based on the geographic shipping location at check-out. All orders in the continental US ship with Free Ground Shipping.

Q: Where do you ship?

A: We ship to the US, Canada, and International. People all over the world enjoy the comfort of Buki.
