My black circle mesh SE Cool Racerback arrived today. I think I am in love! The fit is the exactly same as the regular CRB. I overlayed my new tank to an older CRB and the outline was the same. The circle mesh version is very lightweight. I cannot wait to wear this to spin class tomorrow. I also plan on wearing this tank outside the gym on hot summer days. I like it so much I was almost tempted (again) to order the white version but then I tried on my white Run: Like the Wind tank to check the opaqueness. I can read the Champion logo on the back of my bra through the white circle mesh so white is a no-go for me. Lot of lululemon tanks and tops have circle mesh inserts so I know they have the material to make Circle Mesh CRBs in coal, potion, savage, angel, bubbilicious, passion, mac n cheese, and lots of other colors. Get sewing, Lululemon!!!
