The most comfortable non-heavyweight suit you wear?

I need some sweatpants - tracksuit bottoms -

for spring in French terry.

• as soft and comfortable as possible
• a medium-high waist
• and maybe even with a decent cuff or, even better, straight leg (open at the bottom: close to the ankle, it shouldn't go beyond the shoe)

Do you have any suggestions that might help me find one in 2026?
