The wearable craze isn't only about fashionable watches and savvy glasses. After all, remember how tech giant Intel's vision for the space included a shirt? Hexoskin, a Canada-based startup, has similar beliefs, and that's why it recently introduced its biometric smart tee -- Ralph Lauren's doing it too. The newly developed shirt, aimed at people who are fond of exercising regularly, is equipped with sensors capable of tracking over 42,000 data points every minute. Naturally, given that Hexoskin designed its product with athletes in mind, the shirt's bread and butter is to gather stats during physical training sessions, although it can also track daily activities such as sleep. Unfortunately, Hexoskin's wearable is only available in the US at the moment, where the starting kit sells for a cool $399.
