The Manzella Power Stretch TouchTip gloves combine Polartec's excellent Power Stretch material with conductive thread in the thumb and index finger that allows you to operate touchscreens without taking your gloves off.
Power Stretch has many qualities that make it a great next-to-skin material. It's stretchy and form-fitting, so you don't lose much dexterity like you do with thicker gloves. It also rapidly wicks moisture away from the skin and spreads it out across the upper surface of the fabric, so that it will evaporate and dry faster. If your hands feel dry, it will help them feel warm, too.
For these reasons, Power Stretch gloves work great as liners underneath bulkier ski gloves. You can remove the outer gloves when you need to do finer finger work - or in this case, to operate your smartphone or mp3 player.
The Men's Power Stretch TouchTip gloves are available in Medium/Large and Large/Extra Large only - see the size chart for sizing advice.
