Comments about Sea To Summit Delta InsulMug:

I have now had four of these cups. The first one came with a lid that was too loose. I sent it back and asked for a tighter lid and they sent one that was worse. In the meantime, I ordered one from another company and the lid was tight and it functioned perfectly. I called REI and they sent me another one with a tight lid and told me to keep he one with the loose lid and I decided to try it in the microwave since it clearly states that it is microwavable--IT IS NOT. It melted and made a mess!! The three that remain are very useful for my needs. It is difficult to spill it in and around my desk and computer at work. At home, I use one for my night table for water, a glass of wine, tea, etc. It is great and for me as long as I don't expect the beverage to remain hot, meets my needs. I keep another in my daypack and use that when I go to meetings, conferences, etc. AS LONG AS YOU ASK FOR A TIGHT LID AND YOU DON'T PLACE THE CUP IN THE MICROWAVE, I RECOMMEND IT. It holds two cups and when I dropped it, spillage was minimal; however, the one with the loose lid created a mess in my office when I dropped it. Frankly, for my needs, this has been a great cup. If you heed my advise, you will enjoy this cup.

Comments about Sea To Summit Delta InsulMug:

I bought this b/c a store said it is "must have" gear. After using it I think I'll use my regular REI insulated mug. It does nothing special. You have to get the lid on tight to keep it from leaking. The measuring lines on the inside are hard to read...that would have been easy to make better.The outside where you hold it is pretty cool and feels nice, but the bottom isn't very insulated and heat escapes...it actually gets hot which it shouldn't. The main reason I want an insulated mug is to keep stuff hot and it didn't do that very well.I'd like my [$] back!

It's fairly light weight and the insulation works. The problem is the top leaks like a sieve. For the price, I expected better.

Horrible. Walked to work with coffee in this thing and it was spilling out on my hand (I purposely left about an inch of space thinking this would happen). The lid would never completely seal. I guess I should have heeded the other reviews.

We were super excited to try these out this weekend. They kept the tea hot, but they also leaked out the rim as we enjoyed our hot beverages. We'll be sending them back and looking for something better.

Comments about Sea To Summit Delta InsulMug:

This is a great mug for backpacking. First let's talk about weight. It comes in at 4.4 oz which is 0.2 oz heavier than its most comparable rival, the snow peak double wall Ti mug (450 ml). However, the delta mug comes with a lid which is included in the weight. Once you buy the lid for the snow peak cup (1.1 oz) its total weight comes to 5.3 oz.

Moving on to price, my common sense tells me that 15+ dollars is a bit high for a plastic cup. But when you consider that fact it is three times less expensive than the snow peak mug + lid and has most of the same features, it starts to look a lot more reasonable.

Now lets talk about the material. Comparing the delta with the snow peak is no contest. Titanium is just cool. Its lightweight and virtually indestructible. But ... do you really need that. After all, its just just a cup. If it gets destroyed you could just buy another one and help keep the world economy afloat. Besides, despite the awesome power of Titanium, you still can't heat the the thing on a stove because of the double wall design. And metal conducts heat making it uncomfortable to hold really hot drinks. On the other hand, the Delta Insulmug material feels nice in your hand and doesn't conduct heat from the liquid inside. Also, I personally feel uncomfortable drinking from metal cups, because I get a little paranoid about breaking my teeth in freak "drinking" accident. But that's probably irrelevant for most people.

Some other reviewers have mentioned that the lid doesn't seal properly. The one I bought and all the ones I pawed over at my local REI seemed to have good lid seals. I tested my cup at home and the seal is very good. It doesn't leak at all. Another issue is the microwave symbol. DO NOT MICROWAVE the mug. Mine has a symbol on the bottom indicating that its microwave safe, but its not. The sea to summit website states that early production mugs were erroneously stamped with the microwave safe symbol but are not microwave safe (then or now).

I really like this mug. It's lightweight. It's easy to pack, has great functionality, feels good in your hand, and looks stylish.

Comments about Sea To Summit Delta InsulMug:

I picked this mug up and a snow peak double wall 450 mug today - I saw this on the shelf for the same weight as the snow peak but much cheaper and couldn't believe my eyes. the STS mug I picked out has a very snug, unwarped lid. When sipping from it, there were no spills. I don't intend to actively hike with it while full - I intend to use it for a hot beverage while having sit-down meals at camp. I took them both home and filled them with boiling water, quickly put the lids on, and measured the water temp every 5 minutes for the next 70 minutes (yes, I'm a gear nut). I used an instant-read thermometer from [...]. it took 30 minutes to get down to "piping hot but won't hurt my mouth" temperature, about 150*.70 minutes later, the water in this mug was 120*, which I find to be comfortably warm sipping temp. it seemed to lose warmth at about 1* per minute, give or take. the water lost 10* in this mug as soon as it started, I think because of the plastic absorbing more heat from the water than the titanium did. so, immediately after putting the lids on, this mug read 180 and the snow peak read 190. the snow peak mug lost heat at the same rate, but was always 10* hotter than this one at the same time intervals. This one was comfortable to hold throughout the process, while the snow peak mug was too hot to hold except by the fold-out handles for the first part of the test. the same goes for how hot the mug felt on the lip when sipping. I should note that I used a lid from my travel cup for the snow peak that was a close fit but not snug, since REI doesn't sell the lid for the snow peak. So, my verdict is - great for a sit down meal with a hot beverage or taking your tea into the tent at night with you. Pick one out in person if you can to ensure the lid fits perfectly. I'll be taking the more expensive titanium mug back to REI tomorrow and keeping this one. if you want a spill-proof travel thermos that you can stuff in a mesh pocket and keep on hiking... this isn't the cup for you.

Comments about Sea To Summit Delta InsulMug:

A previous reviewer said that the instructions said it's okay to microwave. Um, they do not. There is an icon on the bottom of the mug that is of a dishwasher not a microwave. If you get one like I did, read the directions, and test the lid for fit before you buy it.

Some people also complain that they would return it if they could find the receipt. If you are an REI member you don't need a receipt.

Comments about Sea To Summit Delta InsulMug:

Well I loved this cup. K-Cop and I carried it the entire PCT. It was our one item of comfort. We cooked coffee most morning and made fun drinks in them. They held up the entire trail and we are still enjoying them. They kept our coffee warm and kept us happy. It was was kind of funny, when we hit Idllywild (130 or something) another hiker saw us pull them out and instead of making fun of us (which happened a little at the beginning of our hike) he went to the store and bought one similar. Its the little pleasures out there that keep you going and this was one of them.

Comments about Sea To Summit Delta InsulMug:

I just took this mug with me on a 3 day backpacking trip into the Sierras. It kept my hot chocolates hot at night and my coffees hot in the morning. Don't buy a mug without a lid if you want your liquids to stay hot. The only drawbacks are that it can retain a smell of the last thing that was in it and that it doesn't pack down, so it can take up precious space in a tight pack. Still, it is worth taking on the next trip.
