Insulation Lid, for 450 Mug

Use the 450's lid camping or driving. Absolutely never drips coffee on me. At least 5 years of use. Coffee stays hot, too.

I’ve used this lid in my 450 mug for years and am very happy with it. I use it at home and on camping trips. I don’t understand the negative reviews regarding leakage. Perhaps they’re storing the lid in the mug, which I assume would eventually weaken the seal. Pretty easy to avoid.

Initially I thought maybe I wasn't creating a good seal with my lips, but after the cup spilt down my chin and on the the floor multiple times it became clear that the ring seal just doesn't cut it. This is incredibly disappointing, since I was planning to use this both on the trail and in the office.

The o-ring that interfaces with the cup is too small and doesn't create a good seal. Your beverage ends up leaking through that "seal" and all over your chin/shirt/lap. Very disappointed. The mug on the other hand is tops.

Unfortunate the lids doesn't work as this would be great morning mug to take to work. There are multiple comments about this issue on REI site. Seems like snow peak doesn't care.
