I have had the 5mm cork mat for many years and absolutely love it. I’m about to go overseas for 6-7 weeks and work away from home often, so I thought to give the 2mm a try. It is amazing! I was worried it wouldn’t provide enough cushion for the knees, but I bought another well known travel mat to compare (won’t name the brand, but the well known rubber one). And the cork is so superior. Amazing grip, so comfy. An absolute staple in my travel kit now! Thank you Zen Vibes ❤️❤️❤️
