Rated 2 out of 5 by ShanTina Just an Ok Mug
The Sea to Summit Insulated Mug is an ok mug. I've taken it car camping and back packing. It seems to hold the heat fairly well, but unfortunately IT LEAKS. I have tried pressing the top down or not pressing it down as hard but neither works and I will be returning it.

Rated 1 out of 5 by JT568 Wouldn't recommend this
I bought one several weeks ago. The size is right; it fits nicely into the one-mug coffee-maker I use (which is why I bought it).
But the seal leaks.
If the coffee inside is not piping hot, the seal is loose, and tends to dribble coffee down your shirt. I've ruined at least two shirts this way.

Rated 4 out of 5 by Andrew64 Delta Insulated Mug
Recently used this mug on a three-day backpacking trip and found that it performed well for my needs. I'm not much of a hot-drink drinker so I couldn't say how long it keeps drinks hot, but it did keep them warm long enough to finish. This mug is fairly small and packs well. Probably 1/3 smaller than a D handle gas station type mug. Weighs very little and the lid stays on well. Washed in the top rack of the dishwasher with no problems.

Rated 1 out of 5 by Ixnorp great disappointment
This mug is poorly insulated. If by "long time" you think it should stay warm for eight or nine minutes, then yes, the mug keeps liquid hot for a long time. This mug does not keep hot liquid hot for more than a few minutes. It gets warm to the touch on the outside, so you can easily tell that it quickly loses heat. We have a lot of insulated drink cups/mugs, and this is *by far* the poorest performer as far as heat rentention goes.
This mug is advertised as "stain resistant". It is not. Tea left in the mug for about ten minutes stained the inside. Fortunately, it did not leave an aftertaste or smell after the mug was washed. At least the top sealed well on our example....

I ordered the SEA TO SUMMIT DELTA INSULATED MUG as a present to myself by using a LL Bean Gift Certificate that I received as a Reward for ordering LL Bean merchandise for Christmas presents for members of my family. The Delta Insulated Mug does Exactly what it is supposed to do and I would recommend it to anyone looking for an insulated Mug for both camping and everyday use. The top fits very tightly and is easy to drink out of. Some people might not like the mug because it does not have a handle, but I like cradling the mug in both hands when drinking from it - especially hot liquids, even though you only feel a small amount of heat radiating through the wall.
I have used it daily for several weeks and cleaning is a cinch. The internal and external walls, including the insulating sleeve have resisted any coffee/tea stains-even if left overnight in the sink without rinsing.

Rated 5 out of 5 by StayFitForever Large Capacity, No Leaks
This mug holds a lot, I actually measured it and it does hold 16 ounces of liquid. It is very lightweight and really keeps my tea or coffee hot for long periods of time.
It is very comfortable to use and does not leak. I would definitely recommend this to a friend.

This a great mug. It holds a lot more liquid than you would think. Keeps coffee hot for quite a while. Goes through the dishwasher (top rack) just fine. The sleeve around the mug should be removed before washing because water will remain behind it if you don't.
I would give it 5 stars but the lid leaks a drop or two when drinking coffee. Might just be the one I have. Not enough to cause a problem but it still leaks.
I will buy more of these for the camp box.
