Are they suitable for full spring, summer and autumn or are they to hot for full summer use?

They’re new this season aren’t they? Doubt may folk have had the chance to use them in hot conditions. That said I’m sure they’ll be fine in the great british summer

They’re winter tights, what conditions do you think they’re appropriate for?

They’ve brought out a bibshort with the thicker material, I assume that’s what th OP is about.

yes the bib shorts.

Just trying to choose between the F1 Mille S5 and these T607 Mille S5 -both bib shorts, having not purchased Assos before.

I use the standard F1 mille from march to October and have never had a issue(great shorts btw). If you use the code NLR-20 at Primera-sports you’ll get them less a extra 20% off or £112.31. 😉

anc – thats the plan 😉 ta though.
