Please note that while this product can be used anytime of the year it is still sensitive to air density.
In colder weather air in the Balloons will contract causing the balloon to deflate a little. Filling the balloon all the way might help it stay inflated. Slight deflation does not mean the Balloon is defective. Keeping the Reusable Balloon inflated in a controlled climate (such as an office) is a good way to test the Balloon.
