Decent yoga mat under £40

[SpikeyHousePlant]

I’ve been doing Yoga for years and my mat is awful now so want to treat myself to a new one.
can I have recommendations please! Can’t afford a Liform one :(

So I do have the Liforme and would recommend if you can afford it but I bought a yogamatters sticky may for my DS when he was a toddler and wanted to join in and I really rate it. We've had it around 7 years now still used regularly by my youngest (and me when she claims mine!) and it is as good as new. Really comfortable, really grippy.
