ION's Neo Zip Top 1.5 women has a more detailed and technical construction than standard rashguards, providing 100% UV protection, efficient heat retention, and a reduction in irritation and bruising, often caused by the harness or surfboard.
I was thinking of a slightly thicker, more durable material because it stretches a little more than I expected. This is mostly annoying to me because although it is good in width, the waist and sleeves are longer, so it feels even more stretchy when I put things in the back pockets. I hope it doesn't stretch in the material either.
