G'day Aaron,

Sea to Summit says not to use these on a fire. The silicone-rubber grip of the handle and the polymer handle thumb latch could be damaged by the heat of a fire or contact with flames. The Sigma pots are made of stainless steel compared to the Alpha with Hard Anodised Alloy however, depending on the heat distribution you may cause irreparable damage to the handle and locking mechanism. If you were super careful to ensure that there was only heat under the pot, and not under the handle, then it might be ok, but there would be some risk, and not something we'd be willing to recommend.

G'day Mio,

Unfortunately, the Trangia 25 series is too big to fit into any of the Sigma pot range.

G'day John,

Yep, you'll have no trouble nesting the 1.9L and 3.7L Sigma pots.

G'day Andrew,

We don't currently have any stock to double-check this but based on dimensions, they should both just fit inside the Trangia Cooker Storage Bag. Alternately, you could use an X-Large size Sea to Summit Stuff Sack. The diameter of the bag base will fit the larger 3.7L pot, and the excess fabric can be folded down over the pot.

G'day Stuart,

Yes, the Sigma pots will work with the Jetboil. Ideally, this would work best for boiling water as the heat is fairly concentrated and may cause hot spots in the middle of larger pots.

G'day Craig,

The Delta Campset 4.4 Set nests inside the Sigma 2.7L Pot or 3.7L Pot, so you could buy one of each of those if you're happy with one pot. Unfortunately due to the design of the Sigma handle means that you can't quite nest the 2.7L inside the 3.7L Sigma.

G'day Vinh Le,

We've previously given the Sea to Summit team a call to confirm, and they've told us that unfortunately, these pots are not compatible with induction cooktops. 

G'day Jules,

Diameter wise, the 230g canister does fit into the 1.2L Sigma Pot, however its about 5mm too tall so the lid doesn't fit!
So close, yet so far!
Hope that helps.

G'day B,

I'm guessing you've watched Ben's handy video of the 1.9L and 2.7L pot, unfortunately the lid isn't the issue, it's the overall height of the pot itself. If you invert the lid the handle will still swing around at the same heigh and cause the obstruction that stops this fitting inside the 2.7L. The 2pcs Set that includes the 1.2L and the 3.7L tends to be the best option.

G'day Thai,

The Sea to Summit Sigma Pots are great, you can use them out camping or at home. They're even compatible with induction cooktops. 

G'day Rhona,

Yes, you can use the Sea to Summit Sigma Pots on a Coleman stove. The main thing you'll want to check is that the flame doesn't lick too far up the side of the pot toward the handle. So we'd probably suggest going for one of the larger two sizes.

It's not actually rubber on the bottom, Mick, it's a black coating that is pretty much flush with the stainless steel and it doesn't impede the ability to nest the pots together.

Keep an eye out on our YouTube channel, we have plans to produce a video showing these pots nesting together. One of the sizes doesn't fit as you would expect it to but I can't remember which one, and we don't have the full range in our store at the moment, once we do we'll shoot some footage to better explain this.

G'day Heather,

I've tried this out just to make sure and the Sea to Summit X Bowl will fit inside the 1.9L Sigma Pot. Just for reference, the Sea to Summit XL Bowl will only fit inside the 3.7L Sigma Pot. 

G'day Ned,

The Sea to Summit Sigma Pots are brand new to the range and as you indicate they look pretty similar to the Alpha Pots. The advantage of going to the Sigma Pot will be the added durability, the grippy black base that will absorb heat and prevent slipping, as well as the option to use a heftier scourer if you accidentally overcook your dinner and get it super stuck to the pot. The disadvantage of the Sigma Pot would be the extra weight as you indicate, but compared to other pots on the market these are still super light.
