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!"

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."

Stephen S. (5/5)

A real find

"This tee shirt proves that you can stay safe and still look good 😊 Beautiful quality, light to wear, excellent fit and the extra arm length to allow you to slide your thumb through, bridges the gap between your gloves when driving! Sits extremely well at your neck under my Solbari shirt, Amazingly well thought out, thank you"
