Gear Review – Sea to Summit Delta Insul Mug

Sea to Summit Delta Insul Mug

Sea to Summit’s Delta mug is designed for campers and back packers, it is a lightweight, insulated mug for either hot or cold drinks making it ideal for the outdoors.

Before we left the UK we sold/donated all of our camping gear – that was back in 2004 and it’s fair to say that even then, some of it was pretty dated. Now with our new found enthusiasm for the outdoors again we need to replace it all.

Sea to Summit’s gear is reasonably priced for the quality that you receive, we are happy with the Delta mugs because they just work, are not fragile, easy to wash and they look good too.

The Sea to Summit insul mug has a moulded rubber sleeve [easily removable] that helps keep your drinks hot ro cold and it it also prevents you from burning your hands. The lid has a snug but not tight fit and has a small lanyard, while the drinking hole may take some getting used to the overall performance is more than acceptable and makes this mug suitable for a range of purposes.

Other features include a hexagon idented base – this prevents slippage on areas where your mug may decide to make a break for it such as smooth surfaces or perched on a rock, the downside to this patterned base is that it is difficult to wash and dry.

How we use them:

We have three Delta mugs, two are used for tea and coffee and one for soft drinks or water, while the mugs are large they fit perfectly into our overlanding storage setup, nor do they rattle around. The mugs never leave base and are used solely as part of our camping kitchen.

For the purposes of overlanding, stopping to make a quick coffee or a more permanent set up at home base the sea to summit delta insul mug ticks all the boxes. At 473ml in volume these mugs are pretty large too which for us is ideal as we like big coffees! For price expect to pay around €13 – 15 euros which is reasonable enough for decent quality gear.

Two years on: We’ve been using these mugs now for two years and they have held up pretty well. The outer rubber on one mug has started to split although these are available from Sea to Summit. Our mugs live in the back of the rig and are used almost every weekend outdoors. Overall, very happy with them.
