Condom Types Explained: Latex, Non-Latex, Ultra-Thin & More
The condom aisle is... a lot. Different materials, thicknesses, textures, sizes, and usually very little guidance on what any of it actually means for you. The good news is it's not as complicated as it looks once you know what you're choosing between.
This article breaks it all down. For a more birds-eye view of the topic, start with our complete Condoms Guide.
First: External vs. Internal Condoms
This is the big fork in the road, and it's less about anatomy and more about how you want to use protection.
External Condoms
The classic. External condoms roll onto a penis/cock/dick, clit, or dildo before sex. They come in a range of materials, sizes, and styles. Correctly and consistently used, they're up to 98% effective at preventing pregnancy and significantly reduce STI transmission.
Internal Condoms
Internal condoms are inserted into the vagina or anus before sex, up to 8 hours in advance. They're made from nitrile (latex-free) and have a flexible ring at each end: one sits inside, one hangs outside. They're compatible with every type of lube and they put protection in the hands of the receptive partner.
According to Planned Parenthood, internal condoms are 79–95% effective at preventing pregnancy depending on how consistently they're used.
Condom Materials: The Real Differences
Latex
Natural rubber latex is the most common condom material: Latex is grown from rubber trees, primarily in South East Asia. It is flexible, strong, widely available, and effective against both pregnancy and STIs. Works with water-based and silicone-based lubes. Not compatible with oil-based lubes, which degrade the material.
The only limitation: latex allergies. Although they affect less than 1% of people, it can cause irritation, hives, or more serious reactions. Also worth knowing, some people who think they have a latex allergy are actually reacting to the additives in the condom, not the latex itself!
Best for: Most people, if there's no latex sensitivity. Safe for sensitive skin.
Polyisoprene
A synthetic rubber that feels almost identical to latex but contains no natural latex proteins, so it works for people with latex allergies. Same level of protection as latex. Use with water-based or silicone-based lube only.
Best for: Latex-sensitive folks who want the closest thing to a latex feel.
Polyurethane
Thinner than latex or polyisoprene, which means better heat transfer and a more skin-like sensation. Works with all lube types, including oil-based. Slightly less elastic, so the fit can feel different, and they tend to cost more.
Best for: People with latex allergies, or those who want maximum sensation and lube flexibility.
Lambskin (Natural Membrane)
Lambskin condoms are made from the intestinal lining of lambs. They do block sperm, so they prevent pregnancy, BUT they do not protect against STIs. The material is porous, which means pathogens can pass through. The research is clear: only latex and synthetic condoms reliably protect against STIs.
Best for: Pregnancy prevention only, and only in a mutually monogamous relationship where STI status is confirmed.
Thickness & Texture: Does It Actually Matter?
Ultra-Thin
Same protection as standard condoms, the thinner profile doesn't compromise safety, it just changes the feel. A lot of people find ultra-thin condoms are the closest to wearing nothing at all, for both partners. They're tested to the same standards as regular condoms, so breakage isn't more of a concern if you're using them correctly.
Standard
The reliable default. If you're not sure where to start, this is fine.
Textured — Ribbed or Dotted
Designed for extra stimulation, usually for the receptive partner. The texture is built into the condom itself and doesn't affect the barrier. Whether you like it is personal, some people love it, some don't notice a difference.

FAQ - Lingering Questions
Can I use an external and internal condom at the same time?
Nope. Using both creates friction between the two layers, which makes both more likely to fail. One condom used correctly is your best bet.
Do ultra-thin condoms break more easily?
No, not when they're manufactured to proper standards. Breakage almost always comes down to incorrect use: wrong size, no lube, wrong orientation. The thinness itself isn't the issue. Check for FDA, Health Canada or CE certification
