It's a bit smaller but I prefer it because I don't like long sleeves in thermal underwear that just ride up. But the long tail, hanging hook and other reinforcing details make this shirt comfortable and pleasing to the eye. if you want to wear this as an extreme shirt. If you can get it for $20 instead of $40, it's really worth it.
