I've been using this glove for trail running and mountain running during the cooler days this year and it has been perfect. I've used them in temps from 35-20 degrees and have tested them with high winds on mountain runs and my hands stayed comfortable throughout. One complaint is that I wish the wrist had a little more tension around the gaiter to really seal the glove.
The "E-Tip" works great (with all fingers) and the grip on the glove is a great feature if you're going to be handling your phone at all (I assume you plan to if you're buying the E-Tip glove). The grip isn't too much, so if you're looking for something thats super tacky, this isn't it. However, I have never felt like I didn't have a secure grip on my phone.
