Since Brodin introduced the "ghost" bags eight years ago, they have become the industry standard. Now it is time to set a new standard. The eco-clear net bags are made from an environmentally friendly material, similar to that used in baby bottle nipples and IV bags and are Made in the USA. Unfortunately all other net bags of this type are made in China and incorporate polyvinyl chloride which has the side effect of releasing dioxin in the production and disposal. These net bags will not yellow or harden in time and they are 25% lighter and softer than other net bags. You should also be aware that mice are attracted to PVC "rubber" and can destroy a net bag if it is left in the garage. Because of the high cost of creating a mold Brodin is starting with one size which is the medium net bag. These will retro-fit all Cutthroat, Gallatin and Stealth model nets and any net with a 39" circumference. Brodin is also committed to creating other sizes in the near future.
