Montane Alpine Edge £100

“Very lightweight & great freedom of movement”

Not everyone needs a chunky, heavy, bombproof pair of trousers for autumn and winter climbs, especially when the conditions are likely to be mild and the pace is going to be fast. Instead you’ll need lighter, more flexible trousers that suit high-energy movement in the mountains. Step up the Montane Alpine Edge pants. They don’t score highly in terms of warmth or durability, but at just 286g they are wonderfully lightweight – half the weight of other pairs on this list – with an athletic cut, comfy fit and great freedom of movement.

Made from Montane’s Chameleon Lite soft shell fabric, which is rustle-free, soft, wicking and breathable, the Alpine Edge pants also feature a reinforced fabric known as Granite Extreme over the knees, seat and in-step. All fabrics have a DWR coating for showerproof protection.

The waist is pre-elasticated and cinchable via a toggle, while the ankles are gusseted with zippers.

IF WE’RE BEING FUSSY

They’re too thin and not warm enough for winter. The pre-elasticated waist isn’t compatible with a belt and the toggle adjustment might not suit all body shapes. They’re only available in one leg length, and there’s no way to tighten the trousers at the ankle or attach them to your boots.

■ MEN’S SIZES S-XXL

■ WOMEN’S SIZES n/a

■ LEG LENGTHS One size

■ WEIGHT 86g (men’s medium)

Verdict

Lightweight trousers for autumn adventures where weight, breathability and comfort are your priority – but they’re not warm enough for the height of winter.
