What makes a good travel coffee mug
A good travel mug keeps coffee hot for 4+ hours and does not leak. Look for: double-wall vacuum insulation (stainless steel), a sealed lid, and a hand-washable design. The Yeti Rambler and Hydro Flask are the gold standard but cost $30-40.
For $15-20, the Zojirushi SM-KHE48 keeps coffee hot for 6 hours and is leakproof. Avoid: plastic mugs (they retain coffee odor), and mugs with sliding lids (they leak). If you drive, get a mug that fits in a cup holder. The lid should have a sipping hole you can open with one hand.
Do not put dairy in a thermos for more than 2 hours - bacteria grows at warm temperatures. For black coffee, 6 hours is fine. Hand-wash the lid - dishwashers break the seal. A good thermos should keep coffee above 140F for 4 hours. Test by filling with boiling water and checking after 4 hours.

Buying advice
Pre-heat the mug with hot water for 30 seconds before filling — it noticeably extends how long your coffee stays hot. Look for a fully sealing lid if it rides in a bag.
