Safety alert: Outdoor Research Meteor mitts have four small magnets on each inner which DO affect a magnetic compass. These are brilliant mitts, but could affect navigation in life-threatening circumstances. I've removed the magnets from mine as of 17 December 2017. I've messaged OR about the problem but have had no response yet.
I'd hate anyone on here to follow a bearing off a cliff in a whiteout because they hadn't noticed these magnets - which are there to hold the folding thumb and finger sections back when wearing the inner mitt alone.
Since posting this alert on Facebook I've had reports of people de-magnetising their compasses when storing them in the same pocket as these mitts. I've also had reports that other gloves have magnets in them and this has caused at least one fell-runner to be lost in cloud for hours when trying to follow a bearing. Other reported sources of magnetic problems for compasses have included magnetic clips for hydration systems, mobile phones and even the Apple Watch. If you're planning to use a compass to navigate (or as a backup for your GPS), check it against your kit before you depart, and don't put it in the same pocket as your phone.
