Wearable fitness trackers are everywhere these days. Everyone has a GPS watch, companies like Jawbone have turned to slightly stranger form factors, while AT&T and Under Armour are putting sensors inside clothing.

The apparel is part of system being called Squid, which also includes a smartphone app and an exercise tracking site.
