I've been wearing my T1 and T2 for about a year now and they're both in great shape still. Took the T1 to L'eroica last October and it was a bit warm, but over here they're spot on.
Any insight into the new fabric you'll be using? Heavier/lighter weight? Same durability?
Fabric will still be merino SportWool, similar weight and durability, me and Al are testing them right now
