Sea To Summit Delta Insul-Mug – Pacific Blue
July 1, 2017 - Comment
This mug features a groundbreaking advancement in thermal insulation. Sea to Summit use an integrated molded Polyurethane sleeve that insulates the liquid inside the mug, unlike double-walled mugs which only protect your hands but don’t keep your beverages hot or cold. Excess liquid flows back into the sipping hole because of the concave design of the lid. Please note that Delta products should not be used in a microwave

Finally, my camping coffee stays hot! Great, lightweight mug. Really does a great job of maintaining the temp of your beverage, hot or cold. Bulky enough that I don’t pack it, but it hangs off the pack by a D-ring. The lid fits tightly enough that it doesn’t come loose. It holds a perfect, generous amount of drink. I’m so glad I got one. 4 stars only because it takes up a fair amount of space if you were to try to pack it inside. If only there were a way to combine the insulating properties of this mug and the collapsible…
Nice but stained easily I bought this mug for a winter camping trip this January. It was nice and kept my coffee warm, comes apart for easy cleaning. I have minor two complaints which prevented it from achieving 5 stars; (1) it will dribble if you are not careful when you drink from it, and (2) it now has a brown stain on the inside. Admittedly, some of the coffee I was drinking was Irish coffee, so maybe that was the cause for the stain.
Lid doesn’t seal right. Dribble. Dribble. Dribble. Arrived with a warped lid. Never sealed enough to prevent dribbling when taking a drink from it. The second one we bought eventually did the same after using it a couple times. Seemed the hot liquid caused the lids to swell and buckle. We ended up buying a different Sea to Summit insulated mug and we are still quite happy with it. This style, however was not great.
