The v-Konstrukt ($70) is a light weight breathable garment with some unique features.  The jersey is long sleeve with vents at the shoulder.  The sleeves are unpadded.  The collar is open and comfortable.

The jersey is constructed of a polyester wicking material.  In addition, there are vents under the arms, front and back.  The collar is a unique horseshoe shape.  This feature works well for donning/doffing the jersey.  For players that prefer higher collars, an under garment will fit comfortably. 

The v-Konstrukt is available in graphite, violet, sulfur and gold.  All colors have the same graphite vent patches.  The v-Konstrukt is true to size, but runs a bit slim.  The arms and waist are a bit narrower.  For players that like to push up the sleeves or prefer a more fitted feel, this is welcome.  For players who like a looser fit, this may be uncomfortable.

There are heat transfer patches on the sleeves.  The outer patch is standard vinyl.  The inner patch is a much stickier silicon intended to aid in stabilizing the ball.  The silicon patches have more of an effect in wet conditions, but were not a hindrance at any time.  They do tend to increase sweat in the area as most heat transfers do.

After several games, we have noticed a few grass stains that will not come out of our gold example, even with a pre-treater.  The fabric does not show any signs of wear, stretching or snags.
