Sea To Summit Delta Insulated Mug

Sea to Summit added a ThermoSkin insulation sleeve to the Delta Insulated Mug in order to help keep your morning coffee nice and toasty for a longer time. The nylon interior disperses heat, is resistant to odors and stains, and makes sure you don't drink toxins. The cool-to-the-touch rim has a self-draining lid that allows drip-free sipping.

Great size, light weight

[This review was collected as part of a promotion.] Great little cup without being to little! I like that you don't have to worry about burning your lips on hot metal. Nice bright color easy to find.

Very lightweight cup!

[This review was collected as part of a promotion.] I got this after making coffee in the backcountry and being very disappointed that my open-top mug helped the coffee go cold in less than 5 minutes after boiling. Still haven't had an occasion to test this mug out, but its insulation seems very nice and the lid is a very well made and well fitting piece that sealed the deal for me. I expect to use this for a very long time. Also very lightweight.

Great for reasons only some of us appreciate

[This review was collected as part of a promotion.] I was torn between buying the Delta Insulated and the X-Mug. Purchased this and very happy with it. Perfect size, liquids stay hot. Sure it doesn’t squish down to save space but if you wipe it down, it nicely stores anything you imagine. Most importantly, we think outdoorsy, deep-woods, high-altitude, happy campers are always in tip-top shape. For me, this mug hits the mark because of that little tassel on the lid and where it is placed. One reviewer said it was useless. If you have RA, finger dexterity issues, Reynauld’s, or any other motor-affliction that may make your hands quiver, that tassel assists greatly to gently pry the lid from the mug without busting your finger nails off or spilling coffee everywhere because you’re using too much force. The smooth surface of the mug is almost too smooth (again if you have any dexterity challenges) but the ridges towards the top are the work around for grip. Great product, S2S!

Hot tea

[This review was collected as part of a promotion.] I like that there’s nothing on the lid to bump into your face like models that close. Easy to hold. Kept liquids warm.

Drippy

This mug is a nice size and keeps contents warm but the lid is terrible. It does not seal at all and drips whenever you drink from the spout. Disappointed by this product considering sea to summit typically sells brilliantly designed high quality products. The delta light mug is much better.

Functionality & Perfomance

I recently took this mug on a 10-day backcountry sheep hunting trip with my dad. My dad took an empty sour cream tub wrapped in tin foil. We both experienced similar functionality & performance. Here's my breakdown. Heat Retention: S2S Mug > Sour Cream Tub Lid Staying On: S2S Mug < Sour Cream Tub Lip Comfort: S2S Mug > Sour Cream Tub Cool Factor: S2S Mug < Sour Cream Tub I'm a big fan of Sea 2 Summit products. However, for this one, there's a bit more to be desired in a $17 mug.

Picked one of these up

Picked one of these up nearly 20 years ago and grew very attached. It served me well until an untimely accident,(that was on me), made it unserviceable. I checked a local outlet as they showed they stocked it, wrong. Ended up going on line with Summit and secured a replacement, actually two of them- just in case. It works well, keeps the hot, hot, has a comfortable grip and travels well. I was sad and now am happy again, thank you Summit.

I was disappointed in this

I was disappointed in this product. I was looking for a light weight cup with lid to keep my coffee hot longer on cold mornings while camping. Unfortunately the lid does not fit tight. I wish I hadn’t gotten it. I ended up using my collapsible silicone cup from Sea to Summit instead.
