Similarities

Thirdly, EVA Cases are coming with more fabrics and linings to be chosen. For EVA Cases fabrics, there are Nylon, polyester, PU leather, Genuine Leather, PVC, lycra, spandex, 600D nylon, 1000 Denier Nylon and mutispandex.
For neoprene bags fabric, the most commonly used fabric is poly and nylon.
Fourthly, Neoprene bags are Easy to wrinkle, so most of the people need to buy another EVA case or nylon backpack to hold the neoprene bag.
Fifthly, EVA Case could have embossed logo on case mold, so there’s no extra cost for embossed logo. Neoprene bags needs to be printed with logo.
Sixthly, EVA Case, could be made as the large EVA case even the extra large EVA cases, such as the boom pole case for ORCA BAGS, fishing rod cases, luggage case, Resqtec NT Hybrid Bag and EVA travel case for ZAMP SOLAR.
For neoprene bags, if the size is too long or too large, it could not keep the shape, since the neoprene material is not rigid, so there will be some pad inside, such as the PP board or EPE foam inside to reinforce the hardness.
Seventhly, The explore Costs are not the same, Every EVA case needs a heat compression mold to yield the shape, but for neoprene bag, it just need the die cutting mold to cut as requested size and make the finished products, so the Development costs of EVA case is more expensive than neoprene bags.
Eighthly, Logo types, Eva case has the plenty of logo types to be chosen, it could have the logo on the EVA case mold, so nobody could use or copy this mold unless they set up a new mold.
But for Neoprene bags, Most of the Neoprene bags are with the silk screen printing logo.
Finally, the Scalability is not the same.
Eva case could be added with other accessories, such as the shoulder strap, carrying handle, carabiner, elastic band inside, mesh pocket, and most of the EVA case are coming with the molded EVA slot or die cutting EVA insert to hold the device and accessories.
But for neoprene bags, the construction is simple, just the pouch or sleeve with zipper or without zipper.
