The pants are very elastic and flexible. It adapts to the body contours perfectly and does not wear out. The material - (partly recycled) polyester and elastane - feels comfortable and you do not sweat it too much. As already mentioned, the pants are cut advantageous. She has several wide seams and a medium-high collar. To the knees, the model has some strange ruffles. Not really my taste, but they are relatively unobtrusive. NOTE: Sizes run regularly. I have it in M, which corresponds to a not overly large size 38. Since the substance is so elastic, the size selection is not quite as problematic as for example when jeans.
Some complain that it is not suitable for very high motion sports (jogging etc.). For this you should know that Soybu specializes in yoga clothing and is also thought these pants for yoga. Yoga I do not operate, but for Fitness / Aerobics, etc. it is equally well suited. In addition, you can of course use the Relax pants to loll around on the sofa fine.
Overall I like the Killer Caboose pretty good. But in direct comparison it intersects slightly worse than those two alternative models.
