Is the iXS Laminat ST-Plus fully waterproof?

Yes. It uses a laminated Gore-Tex membrane bonded to the outer fabric, so rain runs off rather than soaking the shell. Seams are sealed as part of the laminated build.

How does it compare with a drop-liner Gore-Tex jacket?

A laminated jacket like this one does not absorb water, so it stays lighter and dries faster in sustained rain. Drop-liner jackets are usually softer and cheaper but can get heavy when wet.

What sizes does it come in?

It is listed from XS up to 5XL in men's sizing, with half sizes in the US size run. Check the iXS size chart, since European sizing runs differently from US sizing.

Is it good for hot summer riding?

It is built for wet and changeable weather rather than extreme heat. The membrane breathes, but riders in very hot climates may prefer a well-vented summer jacket with a separate rain shell.

iXS textile jackets of this line typically include shoulder and elbow protectors with a pocket for a back protector. Confirm the included armor with the specific listing before buying.
