300mL Silicone Lid

The fit on my Ti-Double 300 is perfectly snug, and since it's all silicone, there's zero metallic taste or clanking when I toss it in my bag. I've knocked it sideways on my desk a few times now and not a single drop escaped. Easily the best lid I've used for keeping my morning coffee hot without any

Fits perfectly on my 300mL titanium mug and creates a really snug seal—no leaks when I shake it. The silicone has just the right amount of flexibility to pop on and off easily.

The silicone is thick enough that it actually seals, no leaks when I tip my mug sideways in my bag. Fits my 300mL mug perfectly and stays put.
