Are rolled / roll-up chess sets legal for tournaments in the USA?

Hi everyone, I'm looking to participate in a few local tournaments and I'm looking to buy a chess set. I like the roll-up ones. Chess sets like this one say "This chess set meets all US Chess Federation tournament requirements" but the FIDE handbook says "...In all cases boards should be rigid" (page 6, section 3.1). Nothing is mentioned on the US Chess handbook (page 14, section 2). Any opinions? I had the same question for weighted or non-weighted pieces, but FIDE says as long as it's comfortable, it's fine. 

Thanks in advance!

Roll-up boards are allowed in US Chess rated tournaments and generally speaking, 90% of them are likely to be. They should be able to lay flat though.

ok, thank you! Do you know if the pieces need to be a certain style or something?

They need to be of normal colors and there are size ranges that acceptable.

You have to bring your own boards?

Sets with 3.75 inch King height are the "standard" size for "official" competition...

The FIDE Manual, Sections 2 & 3, also specifies board and pieces sizes (i.e., for FIDE events)...

Yes, at most tournaments in the US you have to bring boards, pieces, and clocks. In the last few years I've noticed that more events are supplying boards and pieces, but you normally have to bring them. And clocks are almost never supplied.
