the smartwool jerseys are the lightest weight wool jersey i've come across, and very well suited for summer riding. sugoi had some thin wool in their line up, but not currently. also very good in the heat. Ibex are thinner than the traditional wool jerseys, which are more 3-season F-W-S than scorching summer ware.

if people are thinking 'woolistic' or 'kucharik' when you think 'wool jersey', you would be doing yourself a favor trying a new, lightweight summer wool jersey.

I've worn wool in hawaii and all summer on the mainland, but mostly north of the 45th parallel so my idea of 'summer' may be a bit skewed...
