In reply to GarethSL:
We gave it Highly Recommended back in our 2018 Mid-Size Bouldering Mat Group Test and given that I've used it a lot in the intervening years - and it's still going well - I'd give it a double thumbs up. Obvioulsy not the cheapest, but it's lasted well, and the carry system, coupled with the fact you can put all your stuff into it without fear of it falling out, makes it worth the expense (in my eyes).
