Cheap trousers with small defects

We had been dropped a few days before the ski quickly get a new ski pants and have 2 convenient models ordered from Amazon for selection. Quick was to identify which of the two trousers only 20 cost, the cheap model we have excreted the same due to the lower quality.
The pants of Ultrasport looked much more robust, and we wanted to make sure that it does not break right back in a fall. Gaiter and reinforcement on the inside of the legs were also available.
Conclusion after one week skiing course: pants very comfortable and warm. Great price. Unfortunately, the push button is torn off just after a day that should not happen really, especially since my son is very slim. Thank God he stole (with zipper) wear the pants without losing them.
Because of this serious lack only 3 instead of 5 stars.
