The Nineties had Global Hypercolor t-shirts; now we have technology-laden threads – and they don't come much more techy than this Wi-Fi-sniffing tee.
Pop three AAA batteries into the hidden pouch and the front will light up to reveal available signal strength without you ever having to open your lappy.
Cunningly the electronic gubbins that makes it work are fully removable, so it doesn't have to make a date with Persil at 40 degrees like the rest of your laundry.
Admittedly it's less useful when you're wearing a jumper – unless you perform a footballer-esque goal celebration and lift your sweater over your face for others to see. Hmm, could work.
