These is probably the best set of warm weather gear I've ever had -->

More vents than you can shake a stick at....
Not too bad in the rain or cold, so a sort of three season set. The biggest problem is the internal/removable waterproof and thermal parts. But I use mine with some external waterproof gear so it works really well.
Also found a really nice pair of vented gloves from Held ->
