Merino wool is a better fiber for temperature regulation and moisture management because its fibers are finer than other types of wool.  This means they feel softer to the touch when woven together and used to create garments - so right away they are more comfortable to wear.

VIDEO: The hot models and a crowd approaching of mob-like status, just attracted more onlookers for a sneak peek at Castelli's 2019 Spring & Summer cycling apparel collections at their Eurobike 2018 Fashion Show. But I got a PEZ-Clusive first look at the Castelli Alpha RoS cycling jacket.

You've almost certainly seen PRIMAL's custom hoodies, cycling jerseys and bibshorts at a gran fondo, charity ride, or big cycling event you've been to recently, because with over 25 years experience making some of the coolest custom kits around, they're a go to brand for teams, clubs, and corporate events across the US & Canada.

DeFeet Founder Shane Cooper talks socks from DeFeet's newest line - the Evo Mont Ventoux, the new sublimated sock where graphic design is unlimited, and the Wooleator - all while wearing the new UnDLite Sleeveless sublimated base layer designed by Alexander Julian.

Pez talks with Pietro Caucchiolli about the new Alé Bike Wear Cracle jersey & bib shorts for road cycling at Sea Otter 2018. It's a full kit for about $230 - including the jersey and bibshorts - which is a great price for kit that's made in Italy.

Most of us have our favorite kit to wear on when the temperature soars or when it drops during dead of winter. But what about when the temperature is neither blazing hot nor freezing cold? Enter the kit – appropriately named after the Spring Classics when the weather can be cold and windy with a little rain thrown in just for fun.

Designed for going uphill but also excellent for hot rides, the Castelli Climber's 2.0 jersey and Inferno bibshorts have proven worthy accomplices to my summer exploits. Here's my full review, with a long-term look at the bibshorts.

Primal's pro-tour level Helix jerseys and bibshorts are on sale right now at the Primal online shop.

With each piece of gear I test or review, there's usually a eureka moment where I "get it".  For Castelli's Perfetto Light jersey, mine came at the Cyclosportif Megeve in France - on an overcast day in the French Alps where rain came and went.
