I am an avid Striper Fisherman, my favorite time to fish for Stripes is in the Winter.I bought my Arctic Shield stuff just for this (Bibbs,Jacket and gloves.) One morning 2 years ago it was 17 degrees as I launched my boat. Headed out at 40-45 mph for about 12-15 min (to where I was to fish). Didn't get cold. Arctic Shield works for me. I wouldn't wear anything else in the COLD.
