QUICK START

Hot Tommies blends chic design with smart, rechargeable heat so you never choose between looking good and staying warm.

1
CHARGE IT

Fully charge your battery — all four dots means ready to glow. Check by pressing the button on the side of the battery.

2
PLUG IT IN

Connect the battery to the cable inside your left power pocket — same side as the power button — and zip it closed. Make sure the connection is snug.

3
TURN IT ON

Press and hold the power button for 3 seconds. You may need to do this twice the first time — the first press gets things talking, the second locks in the heat.

You’ll feel the heat strongest in the back — that’s where most of the heating elements live. The front panels deliver gentle, even warmth, not a blast, so you stay comfortable and stylish without overheating.

NOT HEATING? FIX IT FAST.

If your vest isn’t heating up properly, don’t stress.

1
Check your charge
Press the button on the side of your battery. If fewer than 4 dots light up, give it a full charge.
2
Test the cord
If the battery isn’t charging at all, try a different USB-C cord, outlet, or power block to rule out the cable.
3
Confirm your connection
Make sure the battery is plugged securely into the cord inside the left pocket — same side as the power button.
4
Double power-on
Press and hold the power button for 3 seconds — you may need to do this twice the first time to connect.
5
Flickering light?
Rapid flashing means low battery. Fully charge again before use.
6
Pro tip
Always unplug the battery while not in use to preserve charge life.
