Question: 40 waist what size I should I order.
Document: I am six feet tall, have a 33 inch waist, and weigh about 170 pounds. The size large fits me perfectly. My rides are generally 30 to 40 miles four or five times a week (every day if I can! ); this short is one of the most comfortable I have worn. After numerous washings the short appears to be well-made. I was so impressed with the short that I ordered a second pair.
Fits well, however it is small. I normally wear Large, I had to get an XL for this one. Order one size larger than normal and you will be happy
I haven't yet taken any longer rides, but these have worked well for rides from 10-40 miles. The material and stitching seems good, and the chamois is comfortable (not too thick, not too thin). I ordered based on the Pearl Izumi sizing chart, and it seemed true to size. The lycra doesn't seem particularly transparent, either, though I've had other shorts with a bit thicker material. In any case, I liked them enough to purchase another pair.
size was perfect,  I have 39 inch waist. The chamois covered my sit bones. Comfortable!
While they would be comfortable in the right size, they are just a bit too small for comfort where its needed yet the next size up would be too big around the legs/waist.
I bought these shorts for motorcycling. I took size med and with waist 33, 5' 7'', 150 lbs it fits perfect. Long distance motorcycling can get tiring and many options have been suggested. I rode a max distance of 600 kms in a day during a recent trip over 2000 Km. I tried wearing the shorts on the longer distance days with an alternate ride without. Must say, it makes a huge difference. For all bikers who have been struggling to find a solution, this is a good option.
The most comfortable bike pants I own. I've worn them as much as 3 times a week on 20 - 40 miles rides and have no complaints.
I ride with these shorts 15 to 40 miles a day five days a week. The padding works well on the longer rides and so far they are holding up well.
The material on the thigh at the saddle wore out in less that three 3 hours riding time. Never have I had such poor performance of a Pearl Izumi product. This order replaced a 3 year old pair Pearl Izumi of shorts that look better that the new ones after 3 hours.
I'm 6 foot and weigh 170 pounds and the medium fit is excellent. Very comfortable. I'm going to order the second pair today.
Answer: yes
