Altura Apex longs are no more, so what baggy longs for off piste trails?

As it asks but you must be able to fit knee pads underneath and not waterproof but do need to cover a big pair of thighs, calves and arse and not too hot for XC rides. My skin on my shins is getting a bit tissue paper like with age and diabetes and the biting insects just love my rotten blood so I get savaged and gorse etc etc shredding my shins. I have an existing pair of Altura Apex longs which are nice and light but they don’t make them anymore and Enduras offerings are a touch confusing as to what they’re aimed at (as well as such mixed reviews regarding sizing and the fact I couldn’t even get a pair of the XXL shorts over my backside and done up).
Google doesn’t seem to have been any help but I’m sure STW will ( but I ain’t wearing veggie wraps either as they don’t come big enough!)

What about 3/4 baggies with knee and shin pads?

I’ve got hard knee shin combo but not for 2-3hrs pedalling plus it still leaves skin exposed for the bloody horse flies/ mozzis that’s why I’m switching back to wearing longs.

I bought some Fox riding pants (trousers) a couple of years ago after a recommendation here but can’t find them now, only their heavy duty downhill versions.

Ground Effect Ranchsliders are great too – I have a pair;

Ranchsliders

Race face ambush: Utterly brilliant fit, very durable, great pocket location, can use real belt with them, good zips and vents.

I pair mine up with some endura undershorts.
