I'm wondering with the large mug + 17 oz it could be a little heavy to lift. What is the weight of the mug?

I am approaching 80 & lift this puppy with my left hand. These mugs are the greatest ever....bar none. Now go buy a pair, U won't regret it !

From frequent washing, even hand washing, has anyone experienced loosening or breakdown of the silicone sleeve?

I haven’t owned mine very long (maybe a month) and I always hand wash. The quality seems superb and based on its current condition, I don’t anticipate the silicone drying out or cracking or otherwise being damaged anytime soon, if at all. These mugs are the only ones I use now and beside of the flat bottom work perfectly to keep my beverage hot when used with my mug warmer. I don’t regret this purchase at all. Word of caution...DO NOT hold the mug by the bottom (fingers underneath) when pouring hot liquids in it. You will get an instant burn.

Do these cups come with any lid?

Yes, every mug comes with a lid, and there is an opening on the lid for putting your stirring spoon or straw. It is quite convenient to use. Hope this helps!

Can you drink from this mug with the lid on?

Yes,but I don't recommend doing so. The lid is not tight and it is easy to cause a spill.
