New Aerolight
I recently purchased an Aerolight quarter zip. I was looking for a light weight top layer for golf that I could also wear around town. I really like the new quarter zip. Great fit, light weight but still keeps me warm for early morning golf. I highly recommend this top.

Looks good feels goof
What I’ve come to expect from Straight Down. Solid.

5 Stars for Aerolight!
I need sun protective clothing due to skin cancer issues. I like to play golf, even on hot summer days, so need something that light and cool. Your Aerolight material is perfect, assuming the SPF 40 factor is accurate. Please keep making these products. Would be great to see this material in other long sleeve shirts.

Sun protection or base layer
I’m not sure if I will keep it, appears too confining for sun protection but might be perfect for a truly light weight base layer at Bandon Dunes?
