A recent golf trip to South Carolina tested the G-Tech Sport 4.0 heated hand warmer amid dropping temperatures and strong winds. The device kept tester Jack Hirsh's hands warm during rounds in chilly conditions. Its features make it a practical accessory for golfers facing cold snaps.
Jack Hirsh, associate equipment editor at GOLF.com, evaluated the G-Tech Sport 4.0 hand warmer during a weekend golf trip to South Carolina. The first two days offered highs in the 70s, but temperatures fell to the 50s with sub-freezing mornings on the last two days. The third day brought highs in the 40s and winds of 20-30 mph, prompting Hirsh to switch from shorts to sweaters and rain pants.
Hirsh noted his personal challenge with cold hands, which affect his grip and shot quality in low temperatures. The G-Tech Sport 4.0, a fanny-pack-style warmer with electric heat, addressed this issue effectively. Powered by batteries supporting USB-A and USB-C charging, it can also charge devices like phones and displays battery levels. It offers over 12 hours of life thanks to an optimized circuit board, software, and 3M insulation, with a waterproof zipper for all-weather use.
The warmer heats quickly on three settings: red for sub-freezing conditions, green for economy mode, and orange for moderate warmth. Hirsh primarily used the green setting. For swings, users can unbuckle the adjustable strap to hang it on a bag or flip it to the back. At the AT&T Pebble Beach Pro-Am two weeks prior, 54-hole leader Akshay Bhatia was seen hanging his G-Tech warmer on his bag.
Hirsh recommended carrying a lightweight bag when walking to keep both hands free in the warmer, noting awkwardness with push carts. For riders, it provides warmth in open carts. Overall, Hirsh found it essential for enjoyable cold-weather golf, reducing issues like thin shots from cold hands, and versatile for activities like football games or garage work.
