TRAIL BLAZER | The Loro Piana wool is treated to be water-resistant; There are 12 pockets, including an exterior smartphone slot; A half-lining makes for a lighter jacket that's easier to layer, easier to tote. F. Martin Ramin/The Wall Street Journal, Styling by Anne Cardenas

TRAVEL WEAR IS too often about trade-offs. Do you take the coat that is warm or the one that is light? The pants that don't wrinkle or the ones that fit? The Travel Blazer from Canadian menswear maker Samuelsohn takes some of the sacrifices off the table: It was designed to be functional, and fetching, too.

Consider the fabric from which this two-button model is cut: a Super 120s wool from Loro Piana. It's soft against the skin, drapes flatteringly and is suitable for all seasons. It's also wrinkle-resistant—crushing a sleeve in your hand (or an overhead bin) barely leaves a crease. Thanks to an imperceptible water-resistant treatment, rain beads off, as does wine. The buttons are durable metal. And the jacket manages to pack in a dozen pockets, including a little exterior smartphone slot and a zippered pocket on the inside that's a perfect place for your passport. You might not want to load up every compartment with gear—bulges look good on nobody—but it's always nice to have options. The blazer comes in navy blue and can be made to order in black. $1,195,
