  • Greetings all,
    I’ve been using my new Frontier X2 for about a week now and I love it 😀 I am curious to see how it performs in below zero temps…. I live above 7K feet in the mountains! In the coming spring, it will be put to the test on some 50mi ultras!

    • There are known problems in low temperature, wearing merino wool or man made poly base layer. Static causes bad data & noise, so buy yourself some anti static spray ready for the cold!
