works great

My experience with field sheer has been a good one

Like their products

Love the down jacket. Warm even without the battery. Love that the pockets warm up and the sleeves have thumb holes. Nice large battery for long lasting heat. Runs a little small but I sized up after reading the reviews. Even then not very loose for extensive layering but I prefer to layer over battery heated clothes to keep the warmth in. This jacket is compact enough to wear a down vest over it.

Prompt delivery and excellent product.
