Underfuse is a performance iron-on pocket specifically designed for working out, running, and travel. It can be used to hold your phone, mp3 player, keys and cards. The pocket is joined to a special woven fabric infused with adhesive. The adhesive is specially formulated to bond to your favorite workout gear with a regular household iron. Underfuse has been tested to be as durable as the item you are attaching it to.
Underfuse is designed to work with all iPhone models (original, 3G, 3Gs, 4G, 4Gs), iPod Touch, most Android phones, most Blackberry phones, and all Palm/HP phones. Underfuse is designed to be bonded to performance textiles such as those made by all the popular sportswear brands. It will also bond to most other fabrics such as cotton. Make sure to test the apparel in an inconspicuous area to make sure it can handle the heat. On men our experience is that it works best when attached to compression shorts right on the front of the thigh. On women’s workout pants/shorts the front of the thigh works great as well. Women also have success attaching Underfuse to a tight workout top above the hip on the side of your body.
