I would be very wary about using a lid that the manufacturers describes as "aid to help protect against the elements eg wind, rain, cold etc"..
I spent a while looking for a helmet for use on water and on land, and found that in the most instances they are either - or.
The one helmet i found that can be used for both ( Wind Things in Edinburgh use them I think) is the Xtreme helmet. It's EEC approved which you need for land, and is also designed for kitesurfing ( has non absorbent foam and covers the back of the neck..)
I spoke to a few shops about this, and they recommended it. £59 from most places, but that's peanuts if it saves your head.
