I like mine a lot, I didn't get one for the 1800 cause I'm
using the little bag on the back of the Utopia backrest
instead of the little tank pouch on the 1500...

Notice the hardware closure on the cap-cover vs the velcro closure
on the little pouch... I'm pretty sure you could tell them which kind of
closure to use at each place if it mattered to you... I've seen their
non-cap-cover bibs that had pouches with hardware closures...
