If you are planning a trip hiking or to an amusement park, you need this pants! I used them for Universal Studios in Florida. It was cool in the AM but warmed up during the day and then got quite chilly in the evening. They kept cool and warm as I adjusted them throughout the day. They also held up great! I can not say enough good things about these pants! They look so nice you can get away with wearing them to a causal dinner. The best part, they are super comfortable!
