A stretchy, weather-resistant softshell vest, keeping your core warm, dry and comfortable.
The Rab Vapour-rise Flex Men's Vest makes fantastic use of their lightweight Vapour-rise technologies, being highly breathable and weather resistant.
With a high wicking micro fleece liner that gives you lightweight core warmth, it's ideal for high energy activity, or as an extra-warm layer for summer evenings.
Matrix SWS stretch side panels ensure you have freedom to move when you're climbing or walking, and when not needed it stuffs away into its own inside pocket - perfect to clip to your belt or pack/harness.
I do really like this gilet - can be worn for almost anything (including keeping warm in the office). It is very effective at providing a convenient middle-ground where a long-sleeved top (jumper, fleece, jacket) would be too warm, but a little something additional is required. It would be especially useful as that first item to go on when climbing and a t-shirt is no longer quite enough - especially when said t-shirt is a bit damp and starting to cool down - but you are still generating quite a lot of heat and sweat
...However, I wore it for 4 days with a rucksack and noted that the back was covered in hundreds of little pills / bobbles of material as the surface degraded. So, great for general use (that chest pocket stores a kindle quite nicely), extremely breathable (only notice quite how good this is when you try a proper windblock gilet instead), not waterproof and in fact barely water repellent...but if it is not tough enough to wear a rucksack on top of then it just isn't good enough.
