These are so comfy and the material's nice and thick and good for rowing or really any activity. They also run true to size so I'd say go with the size that normally works for you.
Just what I needed: no seam in the back.
I used the size chart to choose a M, but I should have gotten a Large.
Great shorts, run small. I’m 5’1 and 100lbs. Would not want these any smaller! Amazingly comfortable- I’ve since bought 4 pair. I’m land locked so rowing on Hydrow and on long rows prior I would end up with a painful rash. Not anymore!
