RTC (Roll Top Closure)
Also: Roll Top Closure, roll closure
With Anfibio's RTC, the tube opens via a special roll closure. That lets you fill the whole interior with luggage.
According to the Packrafting Store, the RTC can't be compared to a normal dry bag roll closure: special materials ensure it doesn't lose pressure even on long trips. It weighs 167 g more than the version without and is fitted to the Anfibio Nano RTC.
