Roady - which way round do you wear the knee/arm warmers (do you have castelli both?)
Seam is ok on arms but should it be round the back of knees and you just get used to it?
Fit/size is spot on, seam isn't uncomfortable, just noticeable.![]()
They should be at the back or slightly at the side (the logo position should give it away), but i had real issues with these when i first got mine. Fine on short rides, but on long rides the seam and particularly where the label was positioned rubbed really badly (even with the actual label itself having been cut away). It made a real mess of the skin behind/to the side of my knee and as well as ending up v painful it would actually make the area bleed if i rode long enough with them. Very stupid design flaw on them.
What I've found over time is that the material around that area has softened a bit and the issue has gone away. One thing you could do is put some Tenacious Tape on the area which might solve it.
EDIT: This was on the Castelli nanoflex btw. I believe Sportful No Rain are identical design.
