When shoppers compare above ground pool liners, they usually see a mix of mil, standard gauge, and heavy gauge language. That is where confusion starts. The reason this CaliMar made by Doughboy liner collection earns the ProPools Pick is that it is positioned around true mil thickness, not vague gauge-only marketing, and additionally these liners are made with the best raw material quality and best seam-warranty positioning in the industry.
A mil is a fixed unit of thickness measurement. A gauge is not a fixed universal thickness standard in pool-liner marketing.That matters because many shoppers assume “heavy gauge” automatically means the same thing as a true 15 mil or 20 mil liner, and that is not the same comparison.
That is one of the biggest reasons this CaliMar made by Doughboy collection earns the ProPools Pick: it gives the customer a clearer, more legitimate thickness story.

Athena is the premium flat-bottom pick because it is positioned around true 20 mil thickness, Doughboy / HII manufacturing, and lifetime seam-separation warranty coverage. It is best for shoppers whose pool is already set up for a beaded-style replacement.
Rio is the best value pick for shoppers who want the HII / Doughboy build story and true mil-thickness positioning without stepping up to 20 mil.
Pebble Springs stands out because it is sold for both 52" and 54" wall heights, while also leaning into virgin vinyl and advanced seam-technology language.
Harbor Lights is the cleanest pick for shoppers who want to stay with a traditional overlap liner and still move into the stronger CaliMar premium-liner story.
Vortex is the right choice for pools with a deeper-center floor up to 60" max depth, combining 20 mil thickness with strong seam-warranty positioning.
Sunset Cove is the deepest expandable option in the collection and is ideal for shoppers who specifically need a premium 20 mil liner for up to 72" max depth.
This collection earns the ProPools Pick because it gives shoppers a clearer and more defensible value story: true mil thickness, stronger material positioning, better sidewall-and-bottom thickness story, and better seam-warranty positioning than more generic gauge-based options.
Start with the CaliMar / Doughboy collection, then use the broader liner catalog and measuring guide if you still need help narrowing the fit.
