Is the 686 Thermal Puff Jacket warm enough on its own?

It is a midweight puffy, not a deep-winter coat. With 160g synthetic fill it handles cold dry days over a base layer, but below freezing you will want a shell over it.

Can it zip into a 686 ski jacket?

686 markets it as a removable liner, so it is designed to pair with 686 shells that use the same zip-in system. Check your shell's liner compatibility before buying.

How does it compare with a down jacket?

The infiLOFT polyfill keeps some warmth when damp and costs less, but down packs smaller and lasts longer for the same warmth. For wet snow and budget, the synthetic fill wins.

What sizes does it come in?

XS through XL. The size chart lists chest, sleeve and length measurements per size, so compare those to a jacket you already own rather than guessing.

When is the best time to buy it?

Prices on insulated layers usually drop in late winter and early spring clearance. At $91.00 as of November 4, 2026 it is already near the bottom of its range, so waiting may not save much.
