Lost in dust and without gear (6)

I believe the answer is:

nudist

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

'without gear' is the definition.
I can't tell whether this defines the answer.

'lost in dust' is the wordplay.
'lost' is an anagram indicator.
'in'+'dust'='indust'
'indust' is an anagram of 'NUDIST'.

'and' is the link.

Can you help me to learn more?

(Other definitions for nudist that I've seen before include "he reveals all" , "S/he prefers to be naked" , "Streaker?" , "Sun worshipper" , "Person committed to going unclothed" .)

I've seen this clue in the Sydney Morning Herald.
