Balloon are very delicate and picky

Like humans, balloons like to be comfortable, they do not like hot or cold conditions. They like to be indoors where it is cool. Our balloons are of the highest quality, when they are first blown up they are glossy finish or translucent, this is temporary, sometimes by the time they get delivered they become opaque or matte finish. This is the result of oxidation. This is normal, because latex is 100% biodegradable.  On hot days, in direct sunlight, balloons may pop within an hour. So in outdoor decorating it is not possible for us to guarantee the balloons will not pop or last through the entire event.  We do however use a larger and more stronger balloon which fairs the heat better. Although wind conditions here in South Texas is not very kind to any of balloon.  So with that said, consider very carefully if you want balloons in your outdoor event.
