Pros
They are made of blended wool which is ideal for heat retention to keep the feet warm for long.
You can detach their battery pouch and attach them to the pockets when the need arises.
They provide heat to the toes where frostbite is likely to attack which in turn heats up the rest of the feet.
You can trust them to stay put even with the battery pouch intact thanks to the reinforced cuff.
They are powered through the use of D cell batteries which supply more heat to ensure they are heated up fast.
You can use them in wet conditions without the fear of shocks.
Cons
The batteries are not rechargeable which means you will need to keep replacing them quite often.
