Brilliant piece of kit
I use my gps primarily for geocaching, and this does the job for my etrex 20. It fits snuggly and allows me to protect the screen while being able to check my location, without removing the unit from the cover. Has a nice strong clip with it so I know the gps is safe on my rucksack and easy to get to. Also the price for a genuine Garmin piece is spot on.
