Hybrid Stone Molds
Black

Developed by Rob Orlando at Hybrid Athletics in Connecticut, Hybrid Stone Molds have been trusted by Strongman athletes for the better part of a decade as a way to produce their own custom-sized Atlas Stones, be it for personal use or as complete sets for multiple athletes in a larger facility.

Unless you lived down the street from an Atlas Stone manufacturer, acquiring these implements in the past generally meant taking on astronomical shipping costs or working out a complicated pick-up. These durable, relatively lightweight plastic molds solve this issue while still enabling a wide range of training options. Molds can be purchased from as small as 10” in diameter (approx. 35 LBS) to as large as 19” (300 LBS), and setting the stones is quite simple.

Each Hybrid Stone Mold divides into two hemispheres. To create an Atlas Stone, start by opening and cleaning the inside of each hemisphere with a lubricant, then re-connect the halves securely via zip ties and position the sphere on a stable base (such as a turned over tire). Create your concrete mix + water at the desired weight corresponding to the mold, then add the mix to the mold using the included funnel, ensuring that the entire mold is filled.

After three days, you can use a tap stick to wedge off the hemispheres and reveal the Atlas Stone, which will also include a Hybrid “H” logo. Any unwanted edges can be smoothed over with sandpaper to complete the process.

Hybrid Stone Molds is rated 4.7 out of 5 by 27.
Rated 5 out of 5 by from Great Product! I use the mold to make atlas balls for my concrete fence. Molds are easy to use and durable material. Lots of complements from my neighbors as the balls were huge and smooth looking.

Rated 4 out of 5 by from Easy to use I've made a couple of Atlas stones using Hybrid molds, now. They're pretty simple to use, and they offer a funnel (I haven't used it) to make things even easier. Some criticism I'd give is that the seam isn't the best design. Slater molds have a better seam design, but they don't have the best options for weights, especially for beginners. Regardless, this will help you make a big heavy rock for picking up, and putting back down, and stuff.

Rated 4 out of 5 by from Quality molds but shrink your logo Hybrid. I’ve been making stones during the lockdown. I have mostly Hybrid molds. Easy to use, clean up nice. One thing stops me from giving 5 stars. The oversized ugly logo. I understand Hybrid want to promote their company. But a smaller logo would be better and wouldn’t effect the actual lifting of the stone. Also putting the weight number on the mold is odd. Depending on product, the stones always weight more. Usually 5-15 pounds more.

Rated 4 out of 5 by from Pretty good but some issues Just finished my Stone came out of the mold pretty easy The main issue is ring were the lips of the mold meet needs some grinding to make it smooth. You should also definitely use a concrete Vibrator when filling or you have quite alot of patch work to do

Rated 5 out of 5 by from Great quality Ordered a 15.5" mold at the start of lockdown. Item was delivered in a very quick timeframe. Unfortunately the mold was 15" . Rogue were very quick with responses when I emailed about it. They offered to send me a new one but i opted just to keep the 15". Rogue still very graciously refunded me the difference and sent me a voucher. Great customer service and product quality. Will be buying more when they come back into stock

Rated 5 out of 5 by from Great Molds These molds make great stones. Some people complain about seepage at the seam, I bolted them together and had minimal water loss at the seams. So far ive made a 95, 145, 215 and 275 and they turned out quite well. Just a little patching on the bottoms as air bubbles were not all removed.

Rated 5 out of 5 by from Works great I've made about 6 sets of stones from these mold so far. They come out great. The only downside was there were no instructions included on how to make the stones. The first 2 sets didn't come out super smooth do to me learning how to make them.
