Which style should I buy?

This is a matter of personal preference. We love the look and feel of down alternative inserts, but others prefer the luxe look of feather down inserts or the ease of machine-washable polyfill inserts.

Feather or down inserts: filled with goose or duck feathers or small, round clusters of feathers known as “down,” and typically the most expensive insert style
Down alternative or synthetic down inserts: filled with polyester fiber, but with the weight of a feather or down insert
Polyfill inserts: filled with lightweight polyester fiber, and typically the most economical insert style
Outdoor inserts: water-resistant shell filled with water-resistant polyester fiber
