Great Warmer Weather Top

Wear it as a base layer in warmer weather or alone as a T-shirt. Dries very quickly. Not sure of the stink factor when worn multiple days. But when sweat soaked on one day pretty much stink free.


Awesome shirt! Can’t wait to wear it on a hike and see how it works in action. Amazing quality!!!

Great sun shirt

First day on Hobe Sound Beach and first day for sun shirt yesterday. Both were excellent. Shirt dries well. Very comfortable swimming in. And no sunburn.

Patrick S. (Prospect, US)
Sunseeker T-Shirt

This is a comfortable tech shirt that is very light. Wore it on a 4 hour hike and it maintained a comfort level beneath the original Sunseeker hoodie and backpack. It won’t be the last one I buy!

Absolute best warm weather shirt

First, I ordered the shirt on pre release last Friday, USPS attempted to deliver to my office near Boston the next day! Second, the shirt is available in tall sizes (as are many of Burgeon's products). Bring 6'4", thank you for not ignoring those of us who need stuff slightly longer. Just flew Into LA this morning to visit my son, and instead of crashing decided instead to go for a 5 mile walk over to Eaton Canyon in the LA heat. The shirt performed superbly in the heat, my baseball cap was drenched but not the shirt. I am amazed how well it did. Best $60 I have spent in a long time.
