Hot in leather, male (7)

I believe the answer is:

thermal

'hot' is the definition.
('thermal' can be similar in meaning to 'hot')

'in leather male' is the wordplay.
'in' indicates the answer is hidden within the clue.
'THERMAL' is hidden within 'leather male'.

(Other definitions for thermal that I've seen before include "which can take a glider up" , "Warm or hot, say air or spring" , "help for glider" , "Updraught for gliders" , "Up-current of air" .)

I've seen this clue in The Telegraph.
