Hmmm...ok well the new cap is good in that there was no slipage with the conditioner in, but I think it lets in more water than a strictly silicone cap. But it was way more comfortable - I can never keep all my hair in the silicone cap. I wonder if it's okay for some water to get in it as long as my hair is wet from the start and has conditioner in it? I guess we'll find out!
