My son is a welder in Prudhoe Bay, Alaska and he works the night shift. This winter it's been -45 to -65 and he was only able to stay outside welding one hour at a time with his arctic clothing. We sent him Simms Rivertek tops & Bottoms and Guide fleece tops & bottoms. He can now stay out in the weather 6 hours!! If this stuff works this well in -65 weather, just thing how warm it will keep you while your fishing. Simms has hit this one out of the Park!
