Possibly the lightest insulated mug you’ll find, the Sea To Summit Delta InsulMug is a Delta Mug wrapped in an insulating PU sleeve and topped off with a sipper lid, now you can have your coffee whilst tackling tough terrain.

Made with tough Nylon 66 material and insulated with non-water absorbing Poly Urethane, the Delta InsulMug also has a leak proof lid that features a sipping port… could also be handy for avoiding coffee stains on the morning train commute!

Featuring a Protex™ base that makes handling hot drinks comfortable, the Sea To Summit Delta InsulMug is about as simple yet ultimately functional as it gets for insulated mugs and is at home in the campsite as it is on the trail or in the office.

  • Wide heat dissipating Protex™ base
  • Non-water absorbing PU insulation sleeve
  • Leak proof sipper lid.
  • Ergonomic heat resistant rim
  • Resists odours and stains
  • Dishwasher safe

Lid problems

The cup itself is super handy and reliable, awesome shape and keeps stuff warm for the perfect amount of time between packing my sleeping bag and setting off for the day’s walk. The only problem I have with my cup is that the lid doesn’t fit very securely on the mug. I’m not sure if this is a problem caused by shipping as I have two of the same mugs and the lid is quite loose on both. However, when there is hot liquid in it the lid seems to fit much better. I have a couple mates with the same mug and the lids on their mugs fit much better

Large and lightweight

Great lightweight mug. Very large too.
Could have an easier pour but not a real issue.

Love Mine

Great if you enjoy a long hot cuppa.
Easy to clean and stain resistant.

***Safety Precaution*** if children are using this mug, supervise closely and make sure the contents are not too hot for the child.

Very happy

Great size for a decent cup of tea and big enough to cook 2 minute noodles in it.

Great product

Awesome light weight product. No hand burning with hot liquids. Only downside is the rubber insulation is really thin and I ripped a chunk out with my fingernails when trying to remove it, so be gentle!!

Size?2 answers

Hi, just wondering if this will fit in a regular camp chair cup holder. I find I can't fit a beer with a stubby cooler on it, so just wondering?

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

Sipper lid 1 answer

Hi there, Can the sipper lid be closed? And does the lid screw onto the cup? If not, is it reliable/leak proof? Thanks very much

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.

Measuring units on the inside?1 answer

Hi. Does this mug have measuring units on the inside?

- Melbourne(1 year ago)

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.
