Bike trousers for the long of leg and slim of waist

He’s 6’3″/6’4″ and 32″ waist.

Lighter weight and breathable end of spectrum.

What bargains are out there?

Alpkit Floe in a long leg might work. I’m 6 foot with a 31″ waist and a pair of 30″ regular leg is pretty good. Tight rather than loose fit but stretchy so not bad. Maybe a 32″ long would be good? Light weight but windproof so seem warmer than some. Think they’re about 80 quid so not a total bargain but not horrific either.
