How does the 3-in-1 system work?

The jacket is a waterproof shell with a puffer liner that zips out. Wear the shell alone in warm or wet weather, the liner alone as a light jacket, or both together for cold days.

Is it warm enough for cold resort days?

With the liner in, it handles typical winter ski days. On very cold days, add a midlayer under the shell.

Can I wear the liner on its own?

Yes. The puffer liner works as a standalone jacket for everyday wear, though it is not waterproof like the shell.

Is it good for snowboarding as well as skiing?

Yes. It is built for both, with 686's snow features and a cut made for riding.

How does it compare with a single shell?

A single shell is lighter and less bulky. The Spellbound trades some of that for insulation you can add or remove, so one jacket covers more conditions.
