The liner is part of a system that includes a waterproof full mitten shell, or trigger finger mitten shell conforming to type I and type II of MIL-DTL-32707. The liner can be worn over a glove insert if desired.

The improved cold weather trigger finger mitten is light weight, reduced bulk, hydrophobic, quick drying, and designed with a trigger finger for weapon operation.The mitten is intended to be used in temperatures ranging from +10 to -25°F (-12 to -32°C). The mitten is compatible with the snow camouflage mitten shells and improved glove insert, and replaces the trigger finger mitten shells and inserts.

The mitten inserts are intended to be worn under the trigger finger mitten shells.

The trigger finger mitten shells are to be worn with or without the wool/nylon mitten inserts and in areas too cold for leather gloves and not sufficiently cold for arctic mittens.

The trigger finger mitten shell is an outer mitten designed to be worn in combination with an insulated liner in extreme cold weather environments when improved dexterity is needed as compared to the limited dexterity a full mitten shell provides.

The shell is part of a system that includes a removable insulated trigger finger mitten liner conforming to MIL-DTL-32708 that can be worn over a glove insert if desired.
