NeoShell is made in 3 basic styles.
Although many jackets made today use the lightweight style – the inner is a simple nylon tricot making for a fabric 1mm thick – there is a middle weight and a heavyweight also.
Here you’ll see the inside of them. The middle is about 1.5mm thick and can be either a velour fleece inside or a grid pattern of fleece (and this fabric is the stretchiest of all of the styles).
The heavyweight version of NeoShell has a higher loft grid fleece inside and is about 2.5mm thick.
