Used these on some snowy, sub zero celsius days and they kept my hands good and warm. The finger covers work well and are relatively easy to take on/off. The lining is synthetic fleece, but soft and comfortable. Fits true to size. The magnets work well holding the finger covers in place, I had some reservations about them conducting cold to my fingers but had no such issues.There were a few loose threads, but the stitching otherwise seems good. Pulling the fingers covers back over will sometimes leave gaps which wind/cold will penetrate. The flare at the back of the glove is not all that deep so it's often won't completely cover my jacket sleeve - I didn't find this to leak in that much cold, but was a gap that snow would occasionally get into.These are much better than any of the cheaper options I've tried - well worth the upgrade. Not quite as good a the more expensive, more reputable brands, but those are also 2-4x the cost.
