Why?
Because they make a terrific difference to our outdoor experience. Basically, wind makes it feel colder than the air temperature around us and putting on a windshirt establishes the equilibrium once more.

Fabric
Of course it needs to be windproof but also breathable. Many today are also water resistant but not waterproof. Basically windshirts are lightweight (often smocks rather than jackets for that reason) if they were waterproof they would be heavyweight!

Don't be fooled by the flimsy nature of the fabric. It is designed to do the job and they are ideal for backpacking, hill walking, cycling and travelling etc. Some have a thin technical lining which adds comfort, warmth and wicks moisture directly off the skin.

Design
A smock style windshirt will be a more generous wider fit as they have to be pulled over the shoulders of the wearer. Certain activities demand a slim tailored fit and others more lose or baggy. For example you may want to wear it over a fleece or under a rucksack, so you won't want it too tailored. We've tried to give an indication of the 'fit' on each item.

Ventilation
Although windproof jackets are generally very breathable, extra ventilation is still an important consideration if the wind suddenly drops, so check out ventilation options. Front zips are essential for this and pockets are often of mesh, which of course is lightweight, but again helps with core venting.

Features
The great benefit of a windshirt is the weight and lack of bulk when packed, just in case. Once this little baby is in your sack it will never leave. Everyone we know who has one, swears by them. For the general UK climate they are perfect 90% of the time, as we get too hot inside a 100% waterproof and too cold with just a mid/base layer. Generally they all pack away into a small stuff sack and are kept in the rucksack side pocket.

Some have hoods which are useful and additional adjustments, but on the whole the simplest shirts are the best. Less weight and easiest to stash.
