Hi Nemix,
Latex can oxidize faster with exposure to air and ozone and ultraviolet light along with other substances that can damage it (see here) so it’s always a good idea for a latex topper to have a dedicated cover to give it the best possible protection and to help maximize it’s useful lifetime. It can also help protect the topper from tearing when you handle it.

[quote]Below is a comparison specs on both Latex toppers I have in mind:
(Memory Foam Canada)
2" Organic Dunlop Latex @ 20 iLD - $280 (pouring process unknown, not zoned)
Terry Cotton Cover - $70, Blended Bamboo Cover (50/50) - $110
(Ton Furniture/Dreamstar Bedding)
2" Talalay Latex @ 28 iLD with Cover - $400 (cover fabric material/zippered unknown will ask, pouring process unknown, might be zoned will ask) [/quote]
I can’t speak to whether either of the toppers you are considering would be a good “match” both for you and the mattress you would be using it on but both of the toppers you are considering are certainly good quality and would be durable choices. The choice between Talalay and Dunlop would be a preference and budget choice rather than a “better/worse” choice (see post #7 here for more about the differences between them).
Just like with a mattress the only way to know for certain whether a mattress/topper combination will be a good “match” for you with any certainty will be based on your own personal experience.
Also like purchasing a mattress … the most important part of the “value” of a topper purchase would be …
-
Careful testing (hopefully using the testing guidelines in the tutorial) to make sure that the mattress/topper combination is a good match for you in terms of “comfort”, firmness, and PPP (Posture and alignment, Pressure relief, and your Personal preferences) … and/or that you are comfortable with the options you have available to return or exchange the topper and any costs involved if you can’t test it in person or aren’t confident that it would be a suitable choice.
-
Making sure that the topper is made from good quality and durable materials (and in this case they would be closely equivalent in terms of durability)
-
Comparing your finalists for “value” based on #1 and #2 and all the other parts of your personal value equation that are most important to you.
There are more comments about mattress/topper combinations in my previous reply in post #4 here.
