Great looking standard capacity water bottle; supple material, easy to squeeze; good top and closure. The bottle diameter, however, seemed slightly too large to slide easily in and out of the cages on five different bikes. (The bottle cages were all different makes) They will fit, but with more effort than seems necessary while riding. Iï¿½ll use them anyhow - and Iï¿½m sure the bottles wonï¿½t fall out. ??
