"I love the crossover design, so flattering. The fabric is great for the gym, compressive but comfortable. The rich navy color is very pretty."
"These have quickly become my go-to leggings for lower body workouts. The crossover waistband creates such a flattering shape, and the material feels flexible and supportive at the same time. They hold up so well during training and still look really sleek styled casually after the gym."
"Love the leggings. They stay up and do not roll and just look great !"
"My first pair of leggings from CSB and I'm very pleased. Fabric feels soft but durable. The crossover snatches you in all the right places. I'm intrigued to try shorts now!"
"Fabric feels really nice and the quality is amazing. All my leggings over the years have lasted very well. Could have a smaller waist band."
"The cross over is perfect, I find others to not look at great on my body, this one does. Definitely a more compressive fit but the top of the tights don’t dig in, which is great as I’m postpartum and have loose skin."
"it is great quality but sadly way too compressive even if I checked the size guide and bought the right chart. It's uncomfortable and I returned everything. I am also very small (45kg/160cm) so I don't who who xs and xxs really are for"
"I love the waist band on these, it's a super flattering cut and the Serenity fabric is beautiful as always. One of my favs!"
"Love these tights ! Very thick material which is very supportive, just find the back could be a bit higher up my hips/waist as I find I need to pull them up quite often during a workout. Love the front cross design though!"
"Have a fair few serenity tights and the crossover is no exception. They all are a great fit and feel"
