Choose if	Anyone who wants daily recovery and sleep scores plus WHOOP Age and health alerts, and would rather pay $239 a year than buy a device outright.	You want Garmin's sleep, HRV and recovery tracking without a screen or a monthly fee.
Main trade-off	It costs $717 over three years with no hardware-only option listed, has no display, and leaves ECG and blood pressure features to the $359-a-year Life tier.	Guided workouts need a paid Connect+ plan, and there's no GPS without your phone.
Key specifications	Membership cost: $239 a year for Peak. One is $199 a year and Life is $359 a year. WHOOP shows only annual pricing. Battery and charging: 14+ days per charge. A full charge of the strap or the PowerPack takes about 2 hours. The Wireless PowerPack slides onto the strap and charges it while you wear it. WHOOP says a fully charged PowerPack holds enough power for up to 30 days to fully charge the sensor. Display and GPS: No display or built-in GPS. You view your data in the WHOOP app. Sensors: WHOOP says its sensors capture data 26 times per second. The pages checked don't name the sensor types. Peak-tier features: Healthspan and Pace of Aging (WHOOP Age), a real-time Stress Monitor, and Health Monitor with health alerts. Peak also includes all One features: Recovery, Sleep and Strain scores, steps and activity, haptic alarm, women's hormonal insights, VO2 max and heart rate zones, and Natural Cycles integration. In the box: WHOOP 5.0 device, Wireless PowerPack and SuperKnit band. One members get a wired Basic Charger and CoreKnit band instead.	Battery life: Up to 10 days from a built-in lithium-ion battery, according to Garmin. Charging takes up to 90 minutes. All-day Pulse Ox and heart rate broadcasting shorten battery life. TechRadar got about a week per charge with three to four workouts a week. Health tracking: Wrist heart rate, Pulse Ox, skin temperature, stress and Body Battery. Sleep tracking covers stages, sleep score, HRV, respiration and naps. Cycle and pregnancy tracking includes past ovulation estimates from skin temperature during sleep. Garmin says that feature isn't meant to help you conceive or avoid pregnancy. Training: Automatic activity detection, plus more than 80 activities you can start by hand. Garmin lists training readiness, HRV status, VO2 max, training status, workout benefit and recovery time. GPS: None built in. Connected GPS uses your iPhone or Android phone's GPS for outdoor walks, runs and rides. LiveTrack shares your location in real time and needs a phone with a data plan. Subscription: None required, according to Garmin. Connect+ adds AI insights, nutrition logging and LiveTrack+. Guided workouts need it, and the manual says some activities may too. It costs $6.99 a month or $69.99 a year. Garmin offered a 30-day free trial when Connect+ launched in 2025. Display and controls: No screen. A single side button starts a favorite activity and snoozes alarms. An LED shows pairing, charging and low battery. The band vibrates for alarms, heart rate alerts and low battery. Water rating: 5 ATM, which Garmin says withstands pressure equal to a depth of 50 m. Swim is in the activity list, but the manual doesn't say what it records in the water. Wear: Wrist or upper arm. Garmin says the wrist gives the best performance. The upper arm band is sold separately at REI. It's 36.0 cm long in S/M and 50.0 cm in L/XL.

Dimensions	WHOOP doesn't state dimensions or weight on the pages checked. Its launch release says 5.0 and MG pack more technology into a form factor seven percent smaller, without giving measurements.	Garmin lists the wrist band at 24.5 cm (9.6 in) long in S/M and 28.5 cm (11.2 in) in L/XL. Both sizes are 2.4 cm wide and 0.2 cm thick. REI says the S/M fits 120–200 mm wrists and the L/XL fits 145–240 mm. Garmin's US page labels part 010-04675-00 only as Black, but Ascent Outdoors lists it as the L/XL. Garmin doesn't give the module's size or weight. TechRadar says CIRQA weighs 21 g but doesn't say whether that includes the band.
Installation	No installation. The strap pairs with the WHOOP app, and WHOOP says you can wear it on multiple locations across the body. Your membership starts when you pair and activate the device, or 30 days after the strap ships.	No installation. You pair it with the Garmin Connect app on your phone.

The owner's manual doesn't mention a warranty, and neither does REI's listing. Garmin's US Consumer Limited Warranty page loads its terms with JavaScript, so they couldn't be read. Check that page before buying.
Returns	You can cancel the membership and return the device for any reason within 30 days of receipt. You get a full refund minus the cost of shipping. The membership page doesn't give terms for canceling after 30 days.	Not confirmed. Garmin's Shipping, Returns & Refunds page loads its terms with JavaScript, so the return window couldn't be read. REI's listing links to its return policy without stating it. Check the policy of whoever you buy from.
Unresolved questions	Device dimensions, weight and water resistance rating Sensor types and published accuracy for WHOOP 5.0 specifically Renewal price, auto-renewal terms and what the strap does after the membership ends How WHOOP Age and Pace of Aging are calculated, and whether anyone has independently validated them Shipping cost and cancellation terms after the 30-day return window FDA status of Peak features beyond WHOOP's own statements (FDA databases weren't checked)	Garmin's own confirmation of which size part 010-04675-00 is, and whether the box includes more than one band The module's size and weight from Garmin Warranty length and return window Charger power draw Minimum phone and operating system versions for Garmin Connect What the fabric band is made of Which real-time workout data stays free, since the manual still lists some under Connect+ Peer-reviewed accuracy data for CIRQA's heart rate, HRV and sleep tracking
