I bought these Calor Pants from Badlands for my cold-weather pants after using the Algus pants during my September Archery Hunt. I knew I'd need something warmer for the winter months of the rifle season so after reading some reviews I gave them a chance. I was able to wear just the merino base layer and these pants and my lower body stayed perfectly warm. Even with a single-digit wind chill and gusty wind, I didn't feel the cold. These pants are awesome. The pants are durable, and I can tell they will last for years. I have warn them only one season, but I know they will be my go-to pants every year for the rifle season. Where I hunt is in the Colorado Rockies and it can get really cold up in the high country. I don't have a doubt these will hold up to the elements and give me the warmth I need year after year!
