Suunto SHRM2 Heart Rate Monitor Could Take On Whoop

Suunto has registered a new device under the model code SHRM2, and the filing details suggest the Finnish brand may be stepping into recovery-wearable territory for the first time. If the most interesting interpretation of those clues holds up, Suunto would be competing directly with Whoop 4.0 and the Garmin HRM-Pro Plus in a segment it has never touched before.

The Whoop comparison matters because that market is built on 24/7 heart rate tracking, HRV monitoring, and sleep analysis without a traditional watch face. Suunto's existing lineup, including the Race and Vertical, already delivers solid HRV and recovery data, but those are wrist watches. A standalone chest or arm strap focused purely on physiological load would be a different product category entirely.

Three possible product directions are on the table based on the SHRM2 filing: a standard chest strap to rival the Polar H10 or Garmin HRM-Pro, a wrist-worn recovery band in the Whoop mold, or something hybrid. The Whoop angle is the most speculative but also the most commercially logical given how fast that segment has grown since 2021.

For endurance athletes, a Suunto-branded recovery wearable would only be compelling if it integrates cleanly with Suunto App training data and delivers HRV accuracy that can match Polar's gold-standard H10 chest strap readings. Whoop's strength is its ecosystem and daily readiness scoring, not just raw sensor quality. Suunto would need both.

Nothing is confirmed yet. But SHRM2 is worth watching closely.
