Don't buy roll-ups
The ones with the vacuum system work far, far better.  This is clumsy and hard to use.  They don't compress well enough and save little space.  Wish they made the ones with the vacuum system in all sizes.  I'd much prefer to just order the medium and large in bulk.  But, they kind of force you to buy various sizes in a single package when you don't need them.
