Xenon Mitten - Men's

I received my Rab Pertex Quantum Mitts for Christmas 2019. I hardly wore them at the start of 2020 as the weather was relatively mild. Despite the few occasions I did wear them I had to stitch a seam on the left hand mit that had split. This winter I’ve worn them quite a lot so far and I’m disappointed that the right hand mit has split across the back seam and the left one has also ripped. I only use them for walking and I would expect these relatively expensive and reputable brand mitts to be more robust.
