Tramping Equipment: Sea to Summit Ultralight Insulated Sleeping Mat

 A new Sea to Summit sleeping mat for 2023

Here is another new piece of kit Karen brought me for my birthday back in August of 2022. It is a Sea to Summit Ultralight Insulated sleeping mat. I have already used this beauty and it made for a comfortable night's sleep.

Sea to Summit Ultra Light sleeping mat

Sea to Summit are one of the larger outdoor gear brands and they make a range of tents, packs, sleeping bags and other outdoor kit for the backcountry adventurer. I have quite a bit of their gear mostly cooking equipment like cutlery, plates, cups and mugs but this is the first sleeping mat I have owned from this company.

Various inflation settings for the Ultralight Mat

The Ultra Light Insulated comes in a number of sizes from X-Small through to Large. My mat is the large size and it is plenty wide and long enough to fit my 6'3" frame onto with space to spare.

Part of the comfort and warmth of the mat is provided by the air cells in the mat. They make small pockets of air under you as you are laying on it which protect you from the ground. The mat has a soft finish to the outer material and it was reasonably quiet when you roll around on it at night. 

Air cell construction adds comfort and warmth

When packed the mat is about the size of a large Nalgene bottle so it is a compact item. There is a stuff sack/pump bag for inflating the mat which is becoming a standard feature for most sleeping mats. It only required five bags of air to fully inflate so it is a breeze to use.

My mat has a insulation layer inside and its R-Value (or measure of how warm it is) is 3.1. This means it would be good to down around 2 degrees Celsius but it would not provide enough warmth for temperatures lower than this. The R-Value can be extended by adding a foam mat underneath but you should really be looking at a mat with a 4.5 or above R-Value for proper winter camping. 


The Ultra Light Insulated has a 3.1 R-Value

This mat would be best suited for use in summer and the shoulder season either side so here in New Zealand that would be from November through March. When inflated it is about 2" thick (5 cm) so it is actually quite comfortable to sleep on. It is thick enough for people like me who sleep on their side to keep your hip up off the ground. 

Technical specifications of the Ultralight Mat

My mat is 600 gm's in total which is not super light but is quite competitive when compared to other brands like Klymit and Thermarest for the same size and R-Value. Sea to Summit are certainly cheaper with this mat retailing for around $320 as compared to the $550 price for a NeoAir XLite from Thermarest. 


All in this looks like a really good sleeping mat and I look forward to using it in the future. 


The Ultralight in use...

So far I have only used this mat on one trip which was my Hawdon Valley camp back in January. As I said at that time I am looking to do more camping trips before I get to old to handle them. My intention is to do several tramping trips a year solely as camping tramps as well as some overnight "Wild Camping" trips.

The sleeping mat performed well and I had a good nights sleep using the mat and my Big Agnes Tent. It is an excellent summer weight mat and it could probably be used down to temperatures around 5 degrees with ease. It was 15 the night I was out and I was actually a bit warm...

The mat fitted into my one person tent and it is a good size to allow me to store gear at the head of the tent with the mat laying flat on the tent floor. For most of the day I had it folded up or stashed behind me so I could sit on the floor of the tent to read, cook etc. 

Gear packed on the last day of the Hawdon Valley camp

This will now become my go to summer sleeping mat and will replace my older Pacific Outdoor mats I have been using for the last 10 years. I am still in the market for a warmer autumn/winter sleeping mat and I am looking at another Sea to Summit product the Ether Light XT. It has a slightly higher warmth rating and is 10 cm's thick so it would be more comfortable.

As always cost is a factor i.e. I need to save up some money to be able to buy another mat so we will see what happens. Keep an eye out for future trips where I am using this piece of equipment.

Tramping Equipment: Lixada alcohol/wood stove system...

 ...more goodies for the gear cupboard...

I received another new piece of kit just after Christmas and it is a real beauty. Karen and I were talking about alcohol stoves one evening and about a week later she presented me with a wood/alcohol stove she purchased from AliExpress. It was the Lixada wood and alcohol stove system.

My Lixada wood/alcohol system

The Lixada company is based in China and they produce commercial cooking equipment and outdoor gear both for their own brand and others. They make a range of cookers, stoves and outdoor dining equipment in a variety of materials. 

Brass alloy cooker from Lixada

Their products are readily available on AliExpress, Amazon, Trade Me and from their online store. I have never seen any of their products in stores here but that is not uncommon with these smaller niche producers. 

While Trangia are the most respected producers of this kind of stove there are a multitude of smaller cottage companies producing good outdoor cooking equipment. Quality is often comparable to Trangia without paying for the name/brand on your gear.

Lixada fit right into this category...

Cooker can be sealed with a cap

I thought we could have a look at my stove and see what the build quality and features are...


The Lixada wood/alcohol stove:

The stove comes as a complete package but the individual components can be purchased separately if required. This kit consists of a stainless steel wood stove which also doubles as a stand for the Trangia style alcohol stove. 


Lixada system: part one is the alcohol stove

Lixada system: part two is the wood stove/stand

The wood stove is of the folding type and can be folded down into a square approximately 12 cms by 10 cms. There is an outer frame and two shelves which fit inside the frame to act as grate and alcohol stove holder. There is an attached pin which fits through a hinge to hold the whole stove together.

The alcohol stove is the classic Trangia style with a brass alloy burner with a cap and simmer ring. The burner can be filled with de-natured alcohol, Methylated Spirits or alcohol gel to preference. Once lit the simmer ring allows you to regulated the size of flame and hence the heat. 

The shelves can be detached from the main stand

There is a separate shelf  that is designed to hold the alcohol burner unit at the right height to heat a pot, frying pan or cup. The whole kit weighs in at 340gms empty which is a decent weight compared to some cannister stoves or pressurised gas stoves. 

There is a Titanium version of this stove system which would take that weight down below 200 gm's but of course it is more expensive.

Both items fold down into small packages and both have a supplied carry bag to protect your gear from soot you might get on the outside of the cooker. You could easily carry the stove in its two bags but I am exploring an alternate carry method...probably a separate 1-2 liter canvas or nylon bag which would hold the stove, cooker and a small bottle of fuel. 


Both Lixada items have a carry bag

The stove can also act as a smaller twig/stick burner with a separate shelf to build your fire on. These type of burners are light as they require no fuel to be carried or separate burners. You just find small, dry sticks and twigs when you stop for the day and light a small fire with them.  

Lixada stove configured for wood

Obviously the disadvantage of this is you must find dry wood which would sometimes be quite tricky in our damp Beech forests. You also need to maintain the fire just like you would a wood burner in a hut...you cannot just leave this and walk away. 

I am not a great fan of wood stoves but I will be using this function in the future. 

You can leave the top shelf inserted using wood 

The alcohol stove comes in three pieces...the main cooker body, a cap and a simmer ring. All are in the same brass alloy and they screw or clip together to form one compact package.

The alcohol stove can accept a number of different fuels including de-natured alcohol, Methylated Spirits and alcohol gel. Meth's is readily available but the gel and de-natured alcohol will only be available from specialist stores in the larger centers. I will primarily use Meth's in my stove. 

Methylated Spirits is the main fuel for the stove

One liter of Meth's is about $3.50 NZD

I was using my old NZ Army cups canteen when I was filming this vlog (it was the only thing I could find) but it is not the ideal pot to use with this stove. It is a bit too high and narrow so the flames tend to curl up the sides. A large diameter and low pot/pan would work best...

A round pot/pan would fit the Lixada stove better

This cup is old...I got it from the NZ Army back in 1987 and I have used it since. Versions of this cup have been in use from the late 1940's right up to the present day and I think it shows the soundness of the original design that it is still useful. This particular pattern is from the Vietnam War era (mine has a manufacturing date on it of 1972).

US cups canteen...over 40 years old now!

The Lixada wood stove is of a folding design and the frame is held together by a pin that fits into an open hinge on one corner. It has a length of wire attached so it can be secured to the frame. If you ever lost the pin it would be easy enough to fashion a new one from some wire.


Preparing to disassembly the Lixada stove

Here is the Lixada wood stove disassembled into its various parts...there is the main frame, a pin and two shelves. You remove the pin and then fold down the main frame into a flat shape using the hinges on each of the corners. The components then fit in the nylon pouch provided with the kit.

All the necessary elements of the Lixada system

This is a decent looking stove and I decided I would find an opportunity to use it as soon as possible. 


Using the Lixada alcohol stove:

There was a fire ban at Kaituna Reserve where I was taking these photos so I could not trial the stove there. It has been hot here in Canterbury and all of the grass and under growth is super dry. I don't fancy the moniker of "man who burnt down 600 year old forest' attached to my name... 

There was a fire ban at Kaituna Reserve

Instead I drove over Gebbies Pass on the way home and stopped at the Allandale Reserve near Governors Bay. There was no fire ban here so I sat at one of the picnic tables and fired up the stove.

I was only using Methylated Spirits this time but I will take the stove out soon and try it burning sticks and twigs to see how it works.

Boiling water on the Lixada stove...alcohol stove being used

I filled my cups canteen and set about boiling some water to hydrate a Cup Noodle I had in my bag of gears. I would probably use this stove for heating water so boiling a litre and then making some noodles seemed like a good trial.

...Alcohol stoves have a slow boil time...

These stoves are not the most efficient means of heating food or water. In all it took nearly 7 minutes for the stove to heat up a liter of water in my old cups canteen. If I was using a wider more shallow pan it would heat quicker but you would still be looking at 5-7 minutes to boil. 

Water starts to boil in the Lixada stove

Eventually the water reached a boil and I used the supplied simmer ring to douse the stove. There is a useful handle on the ring to make it easy to place it over a flame. You need to wait for the stove to cool before screwing the cap back on as it gets really hot. If you do it too soon you will melt or perish the rubber O ring on the cap which makes it leak proof.

These Fantasic Noodles need about 5-10 minutes to fully hydrate so cover them back up with the lid and leave them till they are ready. 


Water added to my noodles from the cups canteen

Once cool the alcohol stove can be removed

This photo shows how the pin holds the whole unit together...it has a large coil of wire on the end to make it harder to loose. If you ever lost the pin it would be easy enough to fashion a new one from a length of heavy grade wire. 

Note: Pin holding the stove together

After use the wood stove folds down into the nylon pouch supplied with the kit and it is a compact item to put into your pack. I will be buying a new bag for this stove so that I am able to carry the wood stove and the alcohol cooker in the same bag.

Fantastic Noodle time....I like these noodles but they are nowhere as good as a genuine English Pot Noodle. You can sometimes buy Pot Noodle from supermarkets here in Kiwiland but I haven't seen any for a while now...Tomato and Beef are my favorite. There are also some cheap off brand local versions available as well as good quality Japanese and Asian noodles here in New Zealand. 

Bon apetit folks...!

This is the sum of all the items you need to use this stove...the stoves, alcohol and wood. I am in the market for a small resealable bottle to carry my Meth's in and I will be looking for one that holds about 500 mls of fuel. That would be enough for 5-6 boils...


Final look at the Lixada stove system

This is a decent stove system and I will taking it out on a few excursions going forward. It is probably best suited for camping trips when I have time to spare for the slow heating times. I will be sure to showcase it the first time I take it out for an actual trip.
