Lightwave's Sigma tents have moved the goalposts with regard to single skin tents - the condensation issue has been effectively tackled, combine this with a stable and spacious 4 season structure and you have a very effective shelter.

Lightwave says:

In 2016 Lightwave launched it's first single-wall trekking tents; the Sigma range. Single-wall tents have always been a rarity in trekking. The age-old problem of condensation has traditionally inhibited their mainstream use. The Sigma range uses a new fabric technology that effectively resolves this fundamental issue.

The ground breaking X-tex fabric used in our sigma tents has an activated carbon coating which absorbs the humidity as it condenses and prevents it from forming droplets. Not only does the interior tent surface feel dry to touch, but the large surface area created by the activated carbon means water molecules remain in a greater state of disassociation and allows them to pass through to the outside more readily and continuously. 

The Sigma tents are optimised for trekking and feature a large porch for storage, easy access and generous headroom.

Lightwave's s10 Sigma Tent is a 4 season free standing shelter with its own poleset weighing in at just 1.1kg, it achieves this awesome statistic by being single skin construction. Single skin puts many people off, especially if they've had a bad night of condensation pooling inside the tent - we like single skin tents but are cool with the consequences - NOW THOUGH, Lightwave's Sigma tents have cracked the condensation issue.

The special fabric keeps the inside of the tent condensation free - feedback we've had from customers confirms this works and is a real breakthrough.

You also get an inner section of the tent made from substantially solid fabric as opposed to mesh - this is also important as it will keep the tent warmer in cooler weather. There's a decent amount of space inside and decent headroom, its a great option for typical UK conditions.

Great tent in so many ways but...

I was prepared to splash out on what is an expensive tent and many boxes are ticked. The design is great with plenty of space for all your gear, particularly when solo, along with my terrier. The tent is quick and easy to put up, pretty robust and not too heavy to carry for one person. A minor issue is that quite a bit of light comes through the lower walls material although it's only obvious when lying down. It wouldn’t put me off buying it however. I wanted to be sold on this tent and would have been but for two issues. After a heavy frost the inside surface will become frosted. This frost must be removed before packing away or it will simply melt Inside the tent. No problem if you have the time to allow the tent to warm up otherwise you will need to turn the tent inside out and shake off the frost. Not insurmountable of course. What seems more important to me was that some condensation is likely to trickle down the internal seams when conditions allow, and can end up on the tent floor. I experienced a downpour for perhaps an hour before ‘getting up’ and when combined with a blustery wind I found a significant accumulation of water, in the form of small puddles, on the ground sheet. This was being shaken off the walls as a fine spray and was not insignificant. Puddles can be mopped off the floor but, more to the point, my sleeping bag etc. was also affected. If I hadn’t experienced the combination of heavy condensation along with that blustery wind I might still have found this very appealing tent. It was with some reluctance that I returned the tent but then UOG provide an excellent service in this respect (issuing a credit).

Does what it says on the tin

Breathes as well as an eVent equivalent, this really is a genuine 2 person option. Plenty space internally though the vestibule and entrance is a little tight. Quiet in wind due to the thicker fabric, easy to pitch too. So far so good.
