Is Futurelight actually waterproof?

Yes. The Futurelight membrane is fully waterproof and windproof, with taped seams and a storm-flapped zip. It is designed as a rain shell, not a water-resistant softshell.

How does it compare with a Gore-Tex jacket?

Futurelight is more air-permeable and softer to the touch, so it breathes better on active days. Gore-Tex shells generally use tougher face fabrics and hold up longer under abrasion and heavy packs.

Does it run true to size?

It runs roomy to allow layering. If you want a closer fit over a base layer only, consider sizing down; if you wear a fleece or puffy underneath, take your usual size.

Can it be packed into its own pocket?

It packs down small enough for a daypack, though it does not have a dedicated stuff sack. The thin fabric rolls compactly.

What is the mesh lining for?

The mesh lining keeps the membrane off your skin, which improves comfort and airflow. It adds a little warmth, so it is best for cool to mild wet weather.
