Rated 4 out of 5 by from TOASTY Hit up some slopes last week when the weather dipped into the low teens and threw a couple of these packets in my gloves to spice things up. Glad I did. My digits were warmer than the inside of a Tauntaun. Pick yo'self up a pack. Your pinkie fingers will thank you.

Rated 4 out of 5 by from Great for cold runs I bought these to put into my gloves during the cold winter months to keep my hands warm during my jogs. They worked really well and kept me from coming home with painfully frozen hands. Definitely recommend.
