Likely for that price you've gotten "premium" mulch which isn't the double milled stuff. Premium is just really a dressy way to call grade B cypress so do watch that for being wet packed and having those slivers I mentioned. Grade A cypress is good stuff, the best I've ever found is sold as "play ground cypress mulch". It's double mill/double shred cypress and is more expensive generally but saves me the incredible hassle of messing about with those darn big slivers.

I think you'll find the mix of cypress and aspen is a very nice balance in some enclosures. It's also quite visually appealing with the blend of the light aspen and the more reddish cypress.
