SAVIOR HEAT Bluetooth Heated Glove Liners for Men & Women, Ultra Thin Rechargeable Gloves with 3 Heat Levels, Touchscreen Thermal Hand Warmers for Winter Skiing, Hiking & Cycling

Why it's worth it

Savior's liner is thin, cut close, and pairs with a phone app, so you can change heat levels without pulling off an outer glove. Graphene elements cover the fingers and the back of the hand across three settings, spanning roughly 104 to 140 degrees.

Changing a setting on most liners means digging for a button through a bulky shell glove, usually with your teeth involved. The app makes that a non-event. You can check battery percentage and drop from high to medium on the chairlift with your phone in one hand. There's a button on the glove as well, so a dead phone doesn't strand you on whatever setting you last picked.

These are the thinnest liners here. The fabric is a soft stretch knit with a non-slip palm, and it layers under a fitted ski glove without the sausage-finger effect. Some owners wear them alone for driving and commuting, which tells you how little bulk there is. If your gloves are already snug and you've had a liner that wouldn't fit, start with this one.
