I wear it around the house as well as on the trail and backpacking. Today's hike was at 10K in the snow in the upper 30's. I was very comfortable and warm with just the Tech Lite with an light insulated vest. It's warm yet has an amazing temperature range up to the 70's. Wicks very well and dries quickly. It stays warm when damp.
