Key features • Three temperature modes let you dial in the warmth you want. • A rechargeable power module delivers steady heat without the bulk of a full warming system. • A soft-touch, heat-resistant sleeve reduces hand fatigue and improves grip in transit. • A secure strap and contour fit help the sleeve stay aligned for even coverage. • Overheat protection and an auto-safety cutoff support worry-free daily use. Charges over USB-C and comes in Slate, Rose, or Sage — a cozy upgrade for commutes, errands, and slow mornings. (Fits most standard travel mugs.)

Fourth one in two years – finally got it right
June 12, 2026
First one: my golden retriever, Barkley, chewed it up after I left it on the counter. He pulled the silicone off and it was just a sad rag. Second one: he managed to grab it off the coffee table and shredded it in the yard. Third one: I hid it in a drawer, but he opened the drawer. This fourth one works because I keep it in my pocket when not in use. It grips tight on the mug, doesn't slide off, and the slate color hides dirt. I wish they'd make a tougher version, but for now, it's the only thing keeping my morning coffee from turning cold while I chase Barkley around.

Better than the old one from the 90s
June 20, 2026
I run a small café and I've seen these come and go. The old ones from the 90s were neoprene and smelled like tire rubber. This HeatGuard is much thinner but keeps heat just as well. The grip is better. The rose color is nice. The only thing I don't like is the seam on the inside, it's a little rough.

Cold snap continues. Mug sleeve performing as expected. Mug of tea stayed warm for 45 minutes in the workshop. The foam lining is still intact after a month. No complaints. If you own one, you know why it's worth it. The slate color doesn't show the motor oil.
