G'day Rebecca,

That would be a question for Sea to Summit directly, unfortunately we don't carry a very big range of parts, so some supplies are happy to help out with these sorts of inquiries.
Even though its not technically a warranty, the warranty team there do deal with spare parts inquires, so submitting a Claom may be the quickest resolution.
Hope that helps!

G'day Tammie,

The Delta Insulated Mug can handle boiling water so anything around the 100'C mark will be fine.

G'day Pina,

The Sea to Summit Delta Insulated Mug can hold about 473ml, so I would say that you'd have no worries at using it for a medium cappuccino. 

G'day Jodi,

I've just given this a quick whirl for you and the Sea to Summit Delta Insulated Mug didn't fit in most of the cup holders on out chairs. There were one or two that it did fit into but I would suggest that if your chair has a "regular" cup holder, then it would probably be a little small. 

G'day Jodi,

Of course, you can! It fit inside the Explore Planet Earth Lightning Chair. 

G'day Whitney, 

I’ve just had a look at the Delta Insulated Mug in store, and the sipper on the lid of the Sea to Summit Delta Mug can't be closed off, and to fit the lid on - you just push down on it.

The seal of the lid is drip proof, but as it’s got a sipper on it, you’re not going to be able to seal this mug off completely. As far as we understand it, the lid is mostly to keep the beverage warm, but if you’re after something completely sealable then the Camelbak Forge is a good option. 

G'day Craig, 

It sure does, the Sea to Summit Delta Insulated Mug has a marking every 100mls on the interior of the mug, as well as the ounce equivalent.
