Whoop, a fitness-and-health tracker with a dedicated following of athletes and fitness enthusiasts, just released its latest low-profile device: the Whoop 4.0. And while you can wear it the old-fashioned way on your wrist, Whoop is also introducing Whoop Body, a clothing collection including high-tech activewear pieces designed to hold the tracker for you.
Trackers from Whoop have gained a following due to the brand’s focus on providing detailed data to help you recover as well as train hard. In fact, personal trainers told SELF previously that they particularly appreciate that Whoop trackers and the companion app provide easy-to-digest sleep, recovery, and strain scores (using measures like heart rate variability, sleep hours, and resting heart rate) to guide their day’s activity and rest levels.
The brand’s latest tracker, the Whoop 4.0, builds on that formula with even more features, a slimmer design, and an upgraded on-the-go battery pack. Those new features include skin-temperature sensing, a pulse oximeter, and haptic wake-up alarms that will ease you out of sleep with gentle vibrations based on your sleep-cycle data. There are also two new types of wristbands designed to work with the Whoop tracker: The SuperKnit is designed to be both comfortable and durable while the upcoming HydroKnit is made to dry quickly after use in water sports.
But perhaps the most innovative part of the new launch isn’t what the tracker can do, but how you can wear it. Alongside the Whoop 4.0., the company is releasing Whoop Body, which includes a training collection of performance-focused activewear (sports bras, leggings, compression tops, etc.) and an everyday intimates collection (bralettes, boxers, etc.) featuring what the brand calls Any-Wear Technology.
This technology allows users to wear their tracker in a pocket on their clothing and continue tracking—no wristband required. Whoop Body will be available in women’s sizes XS to XL and men’s sizes S to XXL, and the brand does plan to expand the lines’ sizes, styles, and materials in the future. Also, note that Whoop Body is only compatible with the new Whoop 4.0, so those with previous versions of the tracker will need to upgrade.
The Whoop 4.0 comes free with a membership to the Whoop app. Whoop membership packages are available in 6-, 12-, and 18-month packages ($180, $288, and $324, respectively). Those who already have a Whoop membership and have at least six months left on it can get a new Whoop 4.0 for free. The company is also introducing a new membership option, Whoop Pro, for an additional $12 per month, which comes with benefits like free shipping and a free item (such as a new band or arm sleeve) every quarter.
