Reviews

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 :)"

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."

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."

Gregory L. (5/5)

Tight and Light

"Tight and Light Holding up the Solbari logo very close to a light bulb indicates that no pinpoint of light is detectable (only visible light bouncing through the white cloth as an afterglow). This is a great indication that damaging wavelengths in sunlight will not get through the high-quality super-tight very light weight weave. A nice design touch is the slit for your thumb which keeps the sleeve from riding up your arm. Perhaps a future design may have a similar slit (with flaps) over your wrist where you might wear an exercise monitor or watch. This will allow a careful peak without compromising the UPF 50+ to the skin of your wrists."

Troy K. (5/5)

The Solbari fabric is extremely

"The Solbari fabric is extremely light weight yet offers protection against the elements yet very cooling even on the hottest days. Each Solbari garment fits like a clove yet moves with you which makes it ideal for sport, leisure and going out. Solbari garments are SBF 50 which is ideal for sun protection and each Solbari garment fits perfectly against your skin."

Base Layer UPF 50+

"Very light and soft material which feels lovely to wear and dries quickly after washing. Exact size as ordered. I purchased this top for my son who is a builder and in the sun all day. I thought it would save him from having to re-apply sunscreen regularly. He has worn it twice and said that he found it to hold in the sweat. He would recommend wearing it if you were in the sun without doing too much physical activity. However, I would still buy this product again."

Tricia B. (5/5)

Amazing

"True fit and very good material looks nice and very light have cold feeling which is amazing and make it light layer"

Diyar H. (5/5)

I know they are called

"I know they are called base layers, but my son uses them instead of t shirts. They are so comfortable, light weight and cooling. This is the second pair I have bought him. He literally lives in them."
