Dry suit hose

[DRE]

This is the kinda hose DUI offers with their suit - just make sure that you can also connect that hose to your BCD inflator. Some of the bigger nipples will be in the way of your corrugated, thus negating the redundant inflation you have between drysuit and wing (disclaimer: there's a lot of different scenarios that would preclude doing this, and a lot of things that need to go wrong before this might be necessary - too many to outline in this post, but my attittude is always to keep all the bases covered, so personally I prefer not to use the oversized nipples on inflator hoses).
