Made in Ontario, the winter wraps are made with a heavy duty black plastic sleeve to soak up heat from the sun, with a layer of aerofoil on the inside for insulation. Super easy to put on and take off, no bunching of insulation or struggling to slip the cover over the hive.
Can be used on single or double brood chamber colonies. If using on a hive smaller than a double, just fold the excess material underneath the lid. You can easily cut the wrap to accommodate whatever style of upper entrance you use.
