• Ready to-Go! This set includes Six (6) Energizer Ultimate Lithium AA batteries so you can use your glove liners as soon as you receive them.
• Keeping your hands warm when it's cold can seem like a losing battle, especially if you need dexterity. Gloves and mittens that are thick enough to keep the chill away often prevent movement and grip. And once your hands are cold, even the thickest gloves won't warm them up quickly. When you step inside or start exercising, your hands sweat and when you stop, your hands freeze even more. This is uncomfortable and dangerous too, since cold, stiff fingers can't grip or manipulate objects as well as warm, limber fingers. Now you can get the warmth you need, when you need it.
• These light, form-fitting flexible liners also have built in moisture management that pulls moisture from hands keeping them dry when you sweat.
• Uses 3 disposable HIGH DRAIN such as Energizer Lithium AA or Nickel-Zinc rechargeable AA batteries in each of the 2 battery packs (6 total - not included). Do NOT use NiMh or NiCd rechargeable batteries. You MAY use Nickel-Zinc rechargeable AA batteries. Low drain batteries such as some Duracell, Eveready or store brand batteries may not work at all or have short duration.
• The included 6 (six) high-drain designed AA batteries are guaranteed to work with your glove liners and are the best suitable batteries available today. They are incredibly light. 3 of these AA batteries weigh less than 1 ounce. Due to the one time use of these AA batteries, there are no warranty returns for AA batteries.

• You will need to replace these batteries each time you use your glove liners as they are not rechargeable
• Machine-washable brushed stretch polyester allows for maximum form fit.
• May not operate with low drain AA batteries such as standard Energizer AA batteries.
• These liners only GENERATE heat for your hands - they do not KEEP them warm so you must wear a windproof INSULATED overglove to trap the heat generated by these glove liners. Wear Inadequately insulated outer gloves is like standing by a space heater outside on a windy day - the heater gets hot but you won't.
