Finally, what you've been waiting for! the USB powered heated gloves. Now not only can you keep your torso warm and toasty with the heated vest/jacket (see here), you can also keep your hands warm! These gloves are again powered with any 5v powerbanks, with a USB connection. Since the power consumption of the gloves are much less, you can use a smaller size powerbank, preferablly a thin design to easily fit in the golve's pocket made for this purpose.
It is waterproof, anti shock and with three levels warmth. Battery not included.
