The Braided Solo Loop Apple Watch band was released in 2020 along with the Apple Watch Series 6. The packaging describes this product as a “Textile Fitted Band.” According to Apple’s website:
“Each Braided Solo Loop features a unique, stretchable design that’s ultracomfortable and easy to slip on and off your wrist. Made from 100 percent recycled materials, the 16,000 polyester yarn filaments in each band are interwoven with thin silicone threads using advanced braiding machinery then laser cut to an exact length. The 300D construction offers a soft, textured feel and is both sweat-resistant and water-resistant.”
This band is (PRODUCT)RED, and was also available at release in Inverness Green, Charcoal, Pink Punch, and Atlantic Blue. It was available in 40mm and 44mm widths, and was among the first Apple Watch band to be sold in specific wrist sizes. The 40mm Braided Solo Loop was sold in wrist sizes 1–9 and the 44mm Braided Solo Loop was sold in wrist sizes 4–12.
According to Apple’s website, “This band comes in custom sizes because it’s designed for an ultracomfortable fit. An accurate measurement will help you get the size that’s right for you.” The website allowed buyers to download a PDF and cut out a “tool” that wrapped around the wrist to designate the band size needed.
Like all Apple (PRODUCT)RED products, part of the purchase price goes to charitable causes. During the COVID-19 crisis, Apple’s website adds, “When you buy the (PRODUCT)RED Braided Solo Loop, we will now send a contribution to the Global Fund to fight COVID-19. Your support can make all the difference.”
I have found this band to be Apple’s most comfortable so far. In my experience, the design allowed the Apple Watch Series 6 sensors to retain constant and consistent skin contact, allowing accurate blood oxygen and heart rate measurements to be maintained.
