Poor lid design

I love my tumbler so much but I’ve tried two of these lids and neither have worked. They work for a week or so but then the rubber seal thing starts to twist and then the lid stops fitting. I wish there was a screw on lid option for the 32oz tumbler because this one doesn’t cut it.

Lid seal

I bought a few Tumblers and a few water bottles. My seal on my lid broke. They sent out new lid asap. Love this company


I love my 32oz Ascent tumbler. Keeps the ice from melting and that's why I specifically bought it for.

Does not stay on

I love this cup but I’m on my third lid. The rubber around the lid slides around making it impossible to open and close the cup. Disappointed.

Replacement lid

Very happy with the replacement lid. Took a little longer than expected to receive though.
