I used mine canada this year tuesday hi of 12 f wednesday 7f and
thursday it was -15 f in the morning and hi was -7 and i olny used 2 heat packs for my
hands. it really helps cut the wind and i put my lunch and thermos in the legs
so when your eating and drinking your hands are in the bag so the deer cant see the movement.the olny change i would/am make is to put a fleece material on the outside to make it extremely sound proof.
i was in it when i got this buck and probaly wouldnt have got him
without it because i would of had to be moving around in the stand to keep warm.
