Sunglasses are fairly compact accessories as it is, but there are just some situations where it couldn’t hurt for them to be a bit tinier. The latest specs fold up to about the size of one lens—perfect for stowing in a jacket pocket or that fabulous-but-miniscule new bag. Once unfolded you’d never even  know their secret.

Stealth Folding Risky Sunglasses $18 at urbanoutfitters.com.

Ray-Ban Folding Aviators from $189, at ray-ban.com.
