Is the Triple Slope warm enough for skiing?

Yes for most resort days when both layers are zipped together. The puffer liner adds recycled-polyester insulation, and the shell blocks wind and snow. On very cold days add a midlayer underneath.

Can I wear the puffer liner on its own?

Yes. The nylon puffer unzips from the shell and works as a standalone jacket for milder days, travel or around town.

Does the hood fit over a ski helmet?

Yes, the hood is helmet-compatible. Without a helmet it sits large, so cinch the adjustments or wear a beanie.

It is designed to fit over a standard sweatshirt, so it runs roomier than a trim ski shell. If you want a close fit, consider sizing down.

Is it machine washable?

Yes. Wash on a gentle cycle and tumble low; avoid fabric softener so the shell's water repellency keeps working.

How does it compare with a single ski shell?

It is more versatile and warmer for the money in features, with two jackets and seven pockets. A dedicated shell is lighter and packs smaller if you already own a good midlayer.
