Wondering if anyone knows a way of transferring gear from a hardcore character to a softcore on?
No way of doing that. Softcore and Hardcore are two separated game modes, with no way of transfering gear/gold/gems/etc between them.
The ONLY thing that is shared are available character slots, which is account wide (Non-season\Season\Hardcore\Softcore).
That does make sense, only character slots are decent enough.
