Query: Nice thickness, but could be grippier

I bought this mat because it's extra long and thick, both of which are solid wins with this mat. The extra thickness is definitely appreciated when on hardwood floors, and as a taller guy, so is the extra length. Keep in mind that the rolled up mat will be thicker, so it may not fit in your yoga bag. The only complaint I have is that the surface isn't as grippy as the other mat's I've had, but it's not bad to the point where I've slipped and fallen.
