The trousers are very well made and the quality of the material and construction is good.
After following the sizing guidance and taking measurements, I ordered a 2XL for my father, who is a full-time wheelchair user. While the trousers fit, I found them to be quite snug around the waist and legs. I am unsure whether sizing up would have been the best solution, as the leg length would likely become even longer.
The adaptive features are useful, but I would recommend that wheelchair users pay particular attention to sizing, especially if additional room is needed for comfort, incontinence products, or prolonged sitting.
