Reviews

2nd purchase of these

"Bought for my son, and they are so good I bought him more. The fit is perfect, the fabric is really comfortable to wear and he needs the UV protection, so that is a bonus. We would like more colours please. It's a shame that men's wear is often only available in a very limited range of colours, none of which are particularly adventurous or pleasing. Not all men want to wear boring colours!"

Base Layer comes up trumps

"The base layers I bought are lightweight, comfortable and provide the sun protection that I was looking for. I play golf and the base layers are essential in helping me maintain high sun protection whilst also enabling me to enjoy the sport, and other outdoor activities"

"Great color in Mid Blue that sold out quickly. . . seriously don't hesitate the cloth does't feel suffocating and offers great sun protection."

Elizabeth C. (5/5)

Amazing

"My husband works all day under the sun even on hot summer days and this blouse is the only one he can wear for best protection! We always end up ordering it again, even if it has to cross continents to reach us!!"

Marina C. (5/5)

Great Tech, Amazing Product

"Can't recommend more as the base layer and technology applied are brilliant. It keeps you dry and protected even on a very warm/shiny day, exactly what they say in the product description. If you are worried about sun/UV protection and have a fresh ink like me, don't hesitate and just order one! Thanks Solbari :)"

Fatih K. (5/5)

I play lawn bowls and

"I play lawn bowls and sometimes we are in the full sun for 8 hours. My base layer UPF 50+ has fully protected my arms and under my bowls shirt. It is a light weight and ultra comfortable garment, almost a second skin and on those high thirties days, I feel it makes me cooler because it keeps the sun from beating directly onto my bare skin. It is an essential piece of clothing for most of my outdoor activities, including walking, bike riding, gardening, tennis and cricket."

George V. (5/5)

I want 10 of them!

"This base layer is perfectly lightweight and comfortable for activities in the heat. Its skin protection is great, I wore it all afternoon playing a round of golf and it was just what I’ve been looking for. Unmatched quality for a summer base layer that will keep your skin protected."
