The 2 included foam windscreens have been upgraded to feature a rubber gasket that keeps it snuggly in place and prevents it from slipping on the lavalier head. The 5 disposable adhesive disks are designed to be used with the 2 pieces of faux fur to create a seal around the lavalier head. The 2 black fluff balls are there in case you need even more wind protection. Using the WLP Deluxe accessory kit alongside the W.Lav Pro will allow you to record in most conditions without fear. The WLP Deluxe accessory kit has enough accessories to cover the Dual-Head WLP and keep stereo setups protected.
