Rain storms have long been a conundrum for cyclists. The dreaded rain cape keeps precipitation off your back initially, but as you get warmer can leave you wetter inside than if you’d left it at home – and also risks catching the wind as you're basically riding in a tent. Likewise, while a standard rain jacket keeps the rain water out, it also seals perspiration in.
For more than 40 years, Gore-Tex has set the gold standard for breathable waterproof performance membranes, offering a solution to the wearable sauna issue. But with its new Core Construction technology, small Colorado-based firm Voormi is aiming to change things up a little.

Voormi's Core Construction claims to bring the advantages of a three-layer laminate fabric down to a single layer
Until recently, laminate fabrics that involve bonding waterproof breathable membranes between two layers of fabric, which have been standard in ski outerwear for some time, have been too heavy for cycling use – and glueing also hinders air permeability. However, with advances in fabric technology we're now seeing more laminated materials used in cycling-specific garments, combining the opposing qualities of waterproofing and breathability.
Gore-Tex, Windstopper, and eVent are all internal membranes, which are sandwiched between two other materials – usually something abrasion resistant on the outside, with a soft liner on the inside. Even the game-changing Castelli Gabba Jersey is made using a Windstopper laminated fabric.
