In reply to Doghouse:
I have Garmin GPSMAP 64. There’s a newer version (66) but they are pretty much the same. Works with winter gloves.
I carry it attached to a shoulder strap just by the hip or to the the shoulder strap itself (see photo below). Been frozen too many times, drenched, bashed against the rocks, etc. still works like new, minus small dent in the screen. Has replaceable AA batteries, which helps for longer trips.
It is 4 or so years old now and hasn’t failed on me ever - saved my ass quite few times in whiteouts!
