Radian® Insulated Stainless Steel

Love it to mix up a protein drink to sip on all day. Stays cold through my work day and even into the evening when I don't finish it at work

Its awesome! Functional, good size, great price

Great bottle, but one little issue

The Radian® Insulated Stainless Steel from BlenderBottle is the perfect size for my needs (fits in the car and gym cup holder) and keeps drinks cold! The only issue I have with this bottle is the ease in which mold/mildew builds up in the cap and it is not easily replaced. This is my second Radian® Insulated Stainless Steel from BlenderBottle, so I am hoping that I can stay on top of cleaning the cap so it does not stain like my previous cap. Again, this would not be a big issue if the cap parts could be easily replaced via Amazon.
