We bought several different water bottles (aluminum, stainless steel, rubber, plastic) at stores such as: Target, TJ Maxx, Marshalls, Dick's Sporting Good's to see what type of bottle fits these Koozies and Wraps. Most everything we bought did fit one or the other. Measure your bottle to see if the following information can help you. Stay flexible. There are many variables when it comes to bottles and please only use this as a guide to assist you . This is not anything written in stone.

Bottle Wraps:  Our tests show the wrap will fit around a bottle that has a bottom diameter that measures no more than 2 1/2" . The wrap is not stretchable but there is a Velcro closer that allows for some down size adjustment.  This included the small slender plastic water bottles (.5L) and the small slender aluminum bottles.  The wrap is very well made and will hold up for a very long time.

Bottle Koozies:  Our tests of varies bottles show the tall neoprene koozies fit bottles that have a bottom diameter of 2 2/3" up to 3". It is a stretchable neoprene material and should hold most metal, plastic, rubber bottles that are considered 1.0 Liter. This is a great choice if you are worried about your bottle sweating. 

Water Bottle Straps:  Our straps fit over the small opening of the bottles that are or are similar to the SIGG aluminum water bottles. Plus openings of plastic water bottles.  Very handy for walks, bike rides or hiking.
