*Due to the nature of this clear silicone material, the boot may fit a bit more snug - especially on special finish cups (Glossy/Shimmery/Etc). If this happens flip the boot inside out, flip cup over, line round inner part of boot up with bottom of cup and roll the sides down evenly. It does fit; it just cannot slide on as easy on certain finishes.
Silicone Tumbler Boot fits most 20-40oz Tumblers
including Simple Modern, Stanley, Hydrojug, Brumate, Yeti, & Owala.
