We offer 3 versions.
- Original (Yellow) The one that started it all. Has a foam core that can hold 1/4 cup of water. This one the CHL Pro prefers and uses.
- Thin (Blue) has the same great foam core as the original; just the material is a tad bit thinner.
- Extreme Thin (Yellow) original material with no foam core instead an extra piece of sham for the core.
