The Koulin’s synthetic fabric is light and stretchy, fitting the body well. Ideally it would be longer in both the arms and the body, both of which felt too short (the sleeves were particularly noticeable, especially when moving the arms). The fabric wicks moisture away from your skin well and is very quick drying. The two side panels add extra ventilation under the arms when you are really working hard and the flat seams ensured there were no sore spots from rubbing. Alpkit have treated the Koulin range with Polygiene to help reduce odour which I found worked well. After several days of heavy activity, the top didn’t feel like it needed washing. The only smell I found was of deodorant but no bad smells, and after washing the top smelled fresh and did not change size. The long-sleeved crew neck was tested but it is also available as a t-shirt or with a half zip neck. Overall it performed very well in both hot and cold climates to wick away sweat and remain breathable. You may not be bowled over by the unsurprising colour options for women – pink and blue – but the Koulin would be a solid addition to anyone’s kit bag based on its performance.
► Verdict: A comfortable base layer which doesn’t need regular washing.
► Best for: Any activity where you’ll get hot and sweaty.
