I bought these gloves for my Kilimanjaro trek back in November, and unfortunately I have to agree with the previous review. On summit night, they failed to keep my hands warm and I was forced to borrow mittens from another team member.
Having said that this review is not all negative. The previous day we had to climb Barranco Wall on a very cold, wet and icy morning and the gloves were brilliant. They were comfortable, warm and kept my hands 100% dry.
Overall I would say these gloves would be perfect for almost all conditions other than extremely cold temperatures.
