Here's what other sites are saying:
Brisk mornings on the trail call for the completely convenient Stanley Clip Grip Mug. This handy mug features a Clip Grip on the handle and a leak-proof lid so you can slowly sip your coffee and clip it to your backpack when you aren't drinking it. The double wall insulation keeps your drink piping hot for a few hours, and it prevents the durable stainless steel outer wall from burning your hands.
