Montane Slipstream Gilet 2011

At a minuscule 80g (size M), the Montane Slipstream Gilet packs down to the size of a golf ball and claims to be the world’s lightest core body protection. It feels almost weightless – but the Pertex Quantum fabric that makes up most of the gilet is windproof and water-repellent, making this a useful extra layer in blowy conditions.
Dryactive Mesh at the rear of the jacket wicks moisture away from the body, while the adjustable scooped tail protects your behind. The 360-degree reflective strips are a nice touch, increasing the visibility of the wearer in the dark.
The Montane Slipstream Gilet is perfect for trail runners and anybody keen to keep pack weight down, but other models are better for colder conditions. The lack of pockets helps to keep the Slipstream light, but could be a disadvantage if weight isn’t your top priority.
The other thing to note is that the elasticated armholes are on the large side, allowing some warm air to escape from the sides, but for its amazingly light weight and small size, this gilet offers excellent performance.
