Designed for winter conditions, the Fjällräven Keb Agile are seriously burly mountain hiking pants made from the brand’s G-1000 Stretch fabric, which is a form of heavyweight softshell. There’s a good degree of stretch here, and the soft backing makes the fabric warm enough for all but the most extreme winter conditions. I haven’t felt the need to layer long johns under them.

Fit is a little tight in the calves, but otherwise good, with a high rise – they sit at my natural waist. I’ve found them the most comfortable of all the trousers tested. Freedom of movement is superb. I like the heavy-duty reinforcement at the knees and ankles.

The ankles will fit over big boots thanks to the zip-expansion hem, and you also get a boot-lace hook. I’ve found that I only need to add gaiters in deep, soft snow. Support is provided by standard belt loops.

The pockets are a highlight. Although the hand pockets aren’t zipped, the two thigh pockets are huge and will swallow several cereal bars. You also get ventilation zips.

For winter use, it’s hard to fault the Fjällräven Keb Agile. But they are high in price, and I’d find them too warm from spring through to early autumn. There is also no women’s version of this precise trouser (the Keb Agile W is a slightly different model).
