The 42 oz size means I'm not constantly refilling during my morning at the desk, and the straw lid makes sipping while typing way easier. The handle feels sturdy too, so I can haul it around the campsite without worrying.

Took this on a three-hour drive and the ice was still rattling around when I got there. The straw lid is what sold me — no more tilting a heavy mug back while I'm driving.

Filled this with ice water before a 6-hour drive and there was still ice rattling around when I got there. The straw lid is the real win though. One-handed sips without unscrewing anything makes it my permanent passenger seat mug.
