This is because the Freeze no mORe is a slow changing heat providing
system much like a radiant heat system in a house. Give it time for
changes to be noticed.

Absolutely not. The insulating pads are made from a special material
called which can reflect 95% of the radiant heat produced. The other
component is polyester stuffing which also provides a degree of
protection. The heat from this device is meant to be directed outward,
between one’s scrub shirt and scrub warm-up jacket or surgical gown. The
heating elements do get hot and should NEVER be used facing the skin.

Yes. First remove the heating pads (see the instructions for use), and
the insulating pads. Launder it with a cold-water, gentle cycle, and
then hang dry. After dry, replace the insulating pads and heating pads,
or just the insulating pads if using the air-activated model.

The Freeze nO mORe is meant to be a personal item brought into the OR
unexposed, over a scrub top and under our insulating vest and then under a scrub warm-up jacket or surgical gown or whatever you typically wear in an effort to keep warm. It can also be worn over a tee shirt and then under a scrub top, with using the Remote FOB, but this set-up may be a little cumbersome to do a battery change.

The Freeze No mORe is composed of materials that are AORN acceptable, but for the most part, it is to be worn unexposed to the OR and therefore it also meets with AORN requirements. There is no endorsement of this garment, at the present time by AORN.

The battery is designed to go through 500 cycles of charging and use.

The battery has internal controls to help maintain the temperature
output. As the battery is depleted, more energy is required to keep the
output (and temperature) constant. As a result of this the duration of
going from 9 to 8 or 8 to 7, is longer than going from 4 to 3 or 3 to 2.

Flashing numbers is just an indicator that the battery is almost completely discharged.

HOT LINER Body Heat Reflective Vest

Yes. The exothermic reaction can be terminated by placing the warmer
into a ziplock bag. Try to eliminate most of the air from the bag prior
to sealing. When opened, and exposed to air, they’ll heat again. 

They can be removed from the pockets and gently shaken. Try to keep the contents evenly distributed to have the most surface area, and then replace the warmers into the pockets.

This vest is able to be laundered by itself, in cold water, gentle
cycle, hang dry. Prior to laundering, be sure to remove any leftover
warmers. No need to launder frequently as it is worn over scrubs and protected by being worn under a scrub warm-up jacket or surgical gown.

If taken care of, and tied loosely around the torso, it can last for weeks.
