4 SET Lithium pack rcB 1200+heat sock 5.0

The battery charge hold and life is the most important feature that I need—the toes stay warm for 8 hours of the day on a low-medium setting. The upper fit of the sock is a bit tight so rolling the long sock to different lengths can be necessary throughout the day. When exercising, the skin under the battery pack gets sweaty so moving it around is ideal for skin breathability. The wearer may have to shift the battery pack weight from front to side so as to not affect your gait or cause ankle strain from running or walking with them. The heat is evenly distributed and comfortable, which is important to all-day outdoor wear in -9 c snow and wind. The battery pack is well-insulated from water, which is key to carefree heavy all-weather use. Overall, I highly recommend them over other brands I have and have bought 2 more pairs so I can wear them more regularly with regular washing/drying for daily/regular winter outdoor work and play.

First time I used them, had trouble with controlling the socks with smartphone. Had to use them manually. Over all They work to keep my feet comfortable and I could stay in my tree stand longer and boy did it pay off. Came home with a 200lb 7 pts buck!
