For my work as a ranger on the North Sea I needed a good warm piece of gear that performed well under all kinds of circumstances. I have to say I almost didn't take this jumper off from when I got it last winter. It's so very comfortable. Really really warm (I mean REALLY) and it breathes very well. It's thick enough to act as a barrier in lighter winds, especially when you're active. The wool is incredibly soft and the knitting is tough while remaining soft to the touch. I personally didn't have to wash this jumper for quit a while, it doesn't smell quickly. I wish I never washed it though, because when I did it came out one size smaller. Beware of non-wool spin cycles on your machine. It's not the temperature setting, it's the spinning that destroys these wonderful jumpers. Buying my second pair now as I cannot imagine winter without the Modros jumper anymore.
