Used this for a year in the army, every season from +20C summerdays to -30C winternights and no complaints. Just put some wool socks on, they help even during summer. They are really heavy duty and will last you a lifetime, just remember to polish them now and then.
Can get these for about $140 online
You can get the newer version which is called M77 Alpha I believe, but they're more expensive
