Silverell Garments
An RF shielding garment that no one will notice.
These typical looking garents do the trick for the upper body and legs! Made from very comfortable 90% Rayon and 10% Silver and tested to 90% or better RF attenuation over the frequency range from 20 MHz to 8 GHz. In addition, the high conductivity of silver causes Silverell to have antistatic behavior, plays an important role in minimizing body odor, and has a strong inhibitory effect on the growth of bacteria (actually acts as an antiseptic!).
Light weight gray fabric. Wash in cold water, delicate cycle, line dry. No bleach. Fabric will pill if used as an outer garment. Suitable for both men and women. Style may vary from photo. Only 1 of each available, do not order more than 1

Bright Eye Bunny
Wearable Technology Project
Make your own circuit with this wearabe Bunny Kit designed by Troy Nachtigall. This kit contains all you'll need to make a soft electronic circuit on a piece of fabric. Then you can sew the fabric to a shirt or jacket to make an e-wearable. The Bunny has an oversized LED eye that turns on in the dark or when you press the fabric push button. When exposed to light the eye stays off. No previous experience of electronics required, all steps are clearly indicated with pictures. Great for students learning about electricity and circuits. Not suitable for young children because it contains a sewing needle.
