How to get a woman camping - buy her this!

I have had a number of different camping mats in the past. I didn't find any suitably comfortable to really get a good night's sleep.

Either they were noisy and rustled - like the Thermarest Neo Air, or the thin 3.8 cm SIM mats my hips did not like and I'd have an uncomfortable night sleep and wake up achey.

I like the Exped Megamats and Sim Comfort mats, but they were too bulky, as what I wanted was to be able to fly-and-hire-car-and-camp, and on occasion do short hike-ins.

This mat is perfect. You get all the comfort benefits of the large Megamat style mats, in a much smaller package. A comfortable fabric sleep surface top, with 8 cm (yes 8 cm!) of thickness from memory foam with air pocket cut-outs. All at a respectable pack-down size of 27 x 15 diam for the regular, or 33 x 17 diam for the large.

This mat was honestly as comfortable as my own bed at home. So if you want to get a woman out camping who hates uncomfortable mats, this mat is absolutely deluxe. I own the bulkier Exped Sim Comfort 7.5 and find this Sea to Summit Comfort Plus SI Sleeping mat more comfortable than that!

So are there any cons, you ask?

A couple.

To roll it back into its little bag, you need to do two rolls of getting the air out. First roll out the mat with the one-way valve. Then have a 2nd go at it, whereby you fold it in half horizontally and roll it up a second time. I've read reviews of people who couldn't get it back in the bag - that's how you do it. (Although you should store it at home in its uncompressed open mat state, like under a bed opened out, and only pack it when you're going camping.)

It seems pretty durable, and it's 30D fabric rather than 20D. However if it does spring a leak, there isn't an enclosed repair kit.

At 900 grams for the regular, and 1.2 kg for the large, it's heavier than a lot of the modern-day hiking mats which are at 350-550 grams. And it's considerably bulkier than the air mats.

However if you love a woman - or the woman loves herself - and she loves comfort - this is the mat!

Ultra-comfortable, much lighter and smaller than Megamat models, and within the realm of possibility to take hiking. (I personally rather pay the weight penalty and take this, and save weight elsewhere like with a down quilt rather than heavier model sleeping bag. However I am using the mat mainly for fly-and-car-camping, and only a little bit for hiking and mostly overnighters.)

Best Sleeping Mat Ever!

I have in recent times slept on a range of thermarest mats but this new Sea to Summit Comfort Plus is amazing. Two weeks of camping and not one uncomfortable night!

Do you need a pump to inflate?1 answer

Need a mat which is kid friendly - easy to inflate.

G'day Simone,

No pump needed with the Sea to Summit Comfort Plus Self Inflating Sleeping Mat. You might just need to blow a few breaths in at the end to firm it up.
