First of all, an Etip is nothing like a reservoir tip. The North Face Etip Glove’s fingertips don’t block the magnetic field emitted by your hands (like Magneto), which is how your iPod’s click wheel operates. You’ll be able to scroll through songs like a pro without taking your gloves off. This is great, now I just need a mitten I can leave on while flicking people off. The Etip gloves cost $40.
