Review on 🥶 Enhance Efficiency with San Jamar PB20 6 Commercial Insulated Product by Will Kern

Good quality. Good material and Velcro straps. Some criticize the lack of ventilation holes. But when it comes to airing, it's like this: too much, and the Bag lets the food cool down prematurely. If the ventilation is too low, the bag turns into a pizza steamer, which is not very good. The amount of food in a bag really determines how much ventilation you need. With more food, you need more Ventilation. The solution is this; The closing valve is your ventilation regulator. Make it tighter for less food and loosen it for more delay. Judge it and you have a solution. All in all a very good bag.
