This is what i wanted! - Arc'teryx Riel Long Sleeve Shirt - Women's

It's very comfortable when you raise your arms when you crouch or fold your arms.

If you increase the fabric, there is no vertical extension, but diagonally left and right, making it easier to move.

It is generous without a waistline and has ample arms. But it doesn't feel like it's full.

The sleeve is not a wrist, but a space that stops at the back of the hand.
