My son and I have been going out for long speed walks so he wanted a pair of exercise/bike shorts as most of his shorts have been causing some chafing...
I didn't have a pattern here as I only brought a few of my Ottobre magazines (and for some reason ended up with more winter ones than summer ones...), so I modified the Ottobre "Print for Free" swimsuit pattern (its not available in English!). The pattern name is Uikkarit and was a great quick pattern to make up. I added 7" to the leg length, and added a little to the back waist, straightening out the back crotch curve. I didn't follow the directions as I don't read Finish, but after making many pairs of leggings and undies, its not too complicated.
The picture isn't great, as I used black lycra!
