I've used this for one season, but it's too warm for me, so I'm selling it as I don't see myself using it in the future. There is some pilling, fraying, stretching, and fading/peeling of the lettering on the outerwear due to wear, but I don't think it's in too bad a condition, so I think it will still be effective as an inner layer. Please refrain from purchasing if you are concerned. I am looking forward to purchases from those who understand that this is a used item. - Brand: Columbia - Model Name: OMNI-HEAT - Model Numbers: Top AE6889, Bottom AE8017 - Color: Black - Type: Underwear / Innerwear - Set Contents: Top and bottom set - Size: Top is untagged.
