These work very well to keep your toes warm in cold, dry weather when you don't need to wear rain booties. Easy to put on. The only downside is the wear on the bottom, but I think this is the case with any toe covers.
It seems like a good windbreaker vest at a great price compared to other brands, but I find LG garments tend to fit larger than optimal. I am 5'7 150lbs and normally wear size S but needed to get XS for a properly snug fit in this.
