"I was skeptical about the runtime claims, but these actually delivered. Ran my usual 2-hour morning route in 28°F weather — hands stayed warm the whole time. No more cutting runs short because of numb fingers."

"Best gift I've gotten! I commute 45 minutes on campus between classes in the cold. Throw one in each coat pocket, turn on level 1, and I'm good for the whole day. No more stopping at Starbucks just to warm up my hands."

"Work 6-hour shifts on the tarmac in freezing temps. These keep my hands functional without the bulk of winter gloves. Been using them daily for 3 weeks — worth every penny. The clip feature is clutch during brutal wind."

"Reffed three back-to-back youth games last Saturday in 25°F weather. Started on level 1, never had to go higher. Hands stayed warm, whistle stayed sharp. These are now part of my game day kit — right next to my cards and coin."

"Shoot outdoor events year-round and frozen fingers kill my ability to work. These slip right in my pockets between shots. The gentle heat on level 1 keeps my hands nimble without overheating. Wish I'd found these years ago!"

"Finally made it through my son's entire tournament without frozen fingers. Level 1 lasted the full game, bumped it to level 2 during halftime when the wind picked up. Game changer for sideline parents!"

Your Questions, Answered Clearly

Hand Warmer delivers three adjustable heat levels:

  • Level 1: Gentle warmth (95–105°F) — perfect for the full game
  • Level 2: Medium heat (105–120°F) — when the wind picks up
  • Level 3: Max heat (120–130°F) — for brutal cold conditions

You control the intensity. Start on level 1 and adjust as needed.

We give you real numbers, not marketing fluff:

  • Level 1: 5–6 hours (most fans stay here the whole game)
  • Level 2: 3–4 hours
  • Level 3: 2–3 hours

Tested by 4,300+ outdoor users. One charge = one full game day.
