Equipment belonging to us is made for severe weather (7)

I believe the answer is:

rigours

I'm a little stuck... Click here to teach me more about this clue!

'made for severe weather' is the definition.
I can't judge whether this defines the answer.

'equipment belonging to us' is the wordplay.
'equipment' becomes 'rig' (rig is a kind of equipment).
'belonging to us' becomes 'ours' (I've seen this before).
'rig'+'ours'='RIGOURS'

'is' acts as a link.

Can you help me to learn more?

(Another definition for rigours that I've seen is " Austere conditions".)

I've seen this clue in The Globe and Mail.
