Crossword Genius

Peter, Len and Walter, swimming, like drysuits (5-9)

Ross

I believe the answer is:

water-repellent

'like drysuits' is the definition.
(drysuits are water-repellent)

'peter len and walter swimming' is the wordplay.
'and' means one lot of letters go next to another.
'swimming' indicates an anagram.
'peter'+'len'+'walter'='peterlenwalter'
'peterlenwalter' is an anagram of 'WATER-REPELLENT'.

(Another definition for water-repellent that I've seen is " Moisture-resisting".)
