Which one would be a better for a late season coat for riding on a 4wheeler and sitting around glassing. More than likely will be snow on the ground and sub-zero temps. The Incinerator Jacket or Blizzard Parka?
Len or Andy at the Long Range Hunting Store will be able to give you some great advise. They have for me in the past with Sitka clothing and did a great deal for me.
I have not had the experience that Drake and Sitka are comparable products. Drake is much heavier and inwas out in the rain all day last week and came out for the most part dry and comfortable. I could never say that with any Drake product I've had. It may just be me but with Sitka I don't ever really feel toasty warm/hot, just never cold. Other gear it seems like I have a bigger swing of sensations.
