I am fully on board the silver luon band wagon, now. My Challenge Tank is probably my most favorite tank these days. I was skeptical of the design (and price!) when it first came out but bought it once they dropped the price to a more reasonable $58. The more I wear this tank, the more I love it. The design is is a lot like a Push UR Limits with the wide straps and mesh back but the material is thicker so it holds you in and shapes you much better plus the flaw/nip coverage is fantastic. I don't have to put the cups in when I wear it to spin and my chest stays in place, even when bent over the bike doing sprints. I find the material more breathable than luon even though it seems a bit thicker.
My silverescent Hot Class tank will be coming this afternoon and I cannot wait to try it on. I am hoping against hope it will be supportive enough for me but I fear my girls will overwhelm the straps. I'll let you all know in my fit report.
Lululemon should make a lot more tanks with silver luon bra portions to give maximum support. The silver luon blows away power luxtreme for compression and shaping. I also would like to see more crop styles in this material - why not silver luon groove and boogie crops in addition to running crops? How about an All Sport or 50 Rep bra made of Silver luon? The Challenge bra was too skimpy for larger busted ladies but I would love a bra in this material. Silver luon in colors would be wonderful, too. Also, please bring back the Challenge tank, it's a great design. All in all, silver luon is awesome.
