I spent a night in a Eureka knock off of the Tadpole in blizzard conditions. Because the sides of the fly come down so low, we had no spindrift in the tent. I did wake up several times during the night feeling claustrophobic, put my hand up and pushed to get the snow off the top of the tent. We were lucky a pole didn't break. I'm not sure the additional panels really add much function to the tent.
