We designed our vacuum bags to achieve the professional results hunters and master chefs demand. Our innovative parallel channel design prevents hidden air pockets while the sturdy 3.5 mil puncture-resistant plastic makes these bags ideal for the big jobs. All bags are reusable, include a space to label the date/contents and are compatible with major vacuum sealer brands. Quart bags have an easy open tear notch. Pack a season's worth of salmon, use for sous vide cooking, even keep your camera dry. These bags are up to the task and all at a price that makes sense.
