Stroll over with most of linen -- it's suitable for jumpers (10)
I believe the answer is:
trampoline
'it's suitable for jumpers' is the definition.
'stroll over with most of linen' is the wordplay.
'stroll' becomes 'tramp'.
'over' becomes 'o' (cricket abbreviation**).
'with' says to put letters next to each other.
'most of' means to remove the last letter.
'linen' with its last letter removed is 'line'.
'tramp'+'o'+'line'='TRAMPOLINE'
(Other definitions for trampoline that I've seen before include "where pike may count in competition" , "Sprung gymnastic equipment" , "Trap oilmen (anag.)" , "Spring up" , "bouncer" .)
