For 2022 we have evolved the award winning Magic Shell by adding bonded and taped seams. Previously overlock (stitched) seams were used to construct the jacket and while the fabric is waterproof, the seams and thread would allow some moisture to seep in during heavy and sustained rain.
The new construction has critical seams bonded (no thread) and then taped. this creates a smooth transition between panels to improve comfort where the seams touch you and improve water repellency. We're still not going to call it 100% waterproof, but it's in the 99% zone.
• Extremely breathable microporous hydrophobic membrane.
• Perfect from 55 degrees to below freezing with appropriate layers.
• Stretchy and Quiet - Doesn't flap in the wind.
• PFAS Free DWR coating + bluesign®-approved fabric.
• 99% windproof and waterproof.
• Active air exchange: (.5cfm) significantly enhances breathability.
• Reflective detailing on front and back.
• Bonded and taped seams (new for 2022) / YKK 2-way double zipper / Made in California.
• Packs down to the size of a water bottle.
Claims of windproof, waterproof, and breathable are typically red flags and met with high levels of skepticism. This was our reaction and only after rigorous testing in which the materials demonstrated significantly better breathability than all other softshell materials did we make our final choice. Due diligence was performed in everything from California sun to California hail. Critical seams on this jacket are bonded and taped, and the main focus of this jacket weather resistant breathability for rides in storms that are not categorized by a number. However, if you find yourself out when the weather turns, this jacket will be your best friend.
Polartec® NeoShell® features a proprietary, patented construction process creating a new hydrophobiac, microporous membrane with a tightly controlled range of pore sizes. It has the durability and stretch of a polyurethane film plus the breathability of a microporous structure. This unique construction allows for positive air exchange to drive moisture vapor release while remaining completely waterproof. It does all of this at a fraction of the weight of current membrane technologies so a garment made of Neoshell is lighter, softer, and more supple.
Dynamic breathability refers to the ability of a fabric to allow movement of body moisture vapor through it; the process is called diffusion. Breathability can be increased by air movement through or around the fabric; the process is called convection. To test for this, one must simulate this environment in a lab mimicking real world condition. The water vapor flux is measured in g/m2/24hours. Higher numbers mean a fabric is more breathable. Polartec Neoshell is 100% more breathable than the best waterproof breathable shells on the market in dynamic or active conditions. Additionally no perceived loss of warmth or windchill is involved within this effect.
