Feel like pyjamas, move like armour. The Runbolds are the lightest pair I tried (341g) and their stretchy, elastic design makes them really suited to mountain moves. Although they’re reliably windproof and reasonably water-repellent, they aren’t very insulated, so they work best if you run hot even on the coldest days. There’s a good high back which supports your lower abdomen and doesn’t get pushed down by the weight of a rucksack. I’d prefer more articulation through the knees, though: the fabric has a tendency to stick to my kneecaps on steep climbs. But if the day warms up, the elasticity of the fabric and lack of heavy abrasion padding means you can roll up the hem easily; I’ve often worn these as three-quarter capris in summer too. Plus you get properly usable hip pockets and a GPS-sized cargo pocket. And the build quality is outstanding, as you’d hope from a brand whose logo has become increasingly covetable in recent years. So at this price (and with decent discounts around), what you’re getting is a very sound investment. Target Price £54.
