I have to say Aligns were never my favorite. Not enough compression and the material just felt too delicate and too naked feeling. They never held up during a hard workout. My collection is mostly Wunder trains for this reason. I absolutely love those. I can wear those to workouts and they are breathable and stay up but I don’t reach for them for lounging around before the gym (I work at home). I have not done an intense work out in the align no lines yet BUT I wore them today for walks and low impact workouts and they were SO comfortable. It feels like aligns and wunder trains had a baby and it was perfect. I can’t wait to try the wunder train no lines. I never even knew the front seam bothered me until I saw how comfortable these were. Now I am not sure I can go back! Which would be a problem since I own a lot of wunder train with seams. Just curious what everyone else’s opinion is and if wunder trains are just as amazing with no front seam!
