Non-latex condoms come in four main materials: polyisoprene (synthetic rubber), polyurethane (thin plastic), nitrile (synthetic rubber), and lambskin (natural animal membrane). Each has distinct tradeoffs in feel, protection, and lubricant compatibility, so the best choice depends on why you’re avoiding latex in the first place.
Polyisoprene Condoms
Polyisoprene is the most popular non-latex option on the market today. It’s a synthetic rubber that mimics the stretch and fit of latex without containing the proteins that trigger latex allergies. Because it’s stretchier than other non-latex materials, it conforms to the body more naturally and is less likely to slip during use. Many people find it difficult to tell apart from latex by feel alone.
The SKYN line (Original, Elite, Supreme Feel) is the dominant brand in this category. Durex Real Feel and Trojan’s non-latex condoms also use polyisoprene. These are widely available at drugstores and online, and they’re typically priced only slightly above standard latex condoms.
One important note: polyisoprene condoms are not compatible with oil-based lubricants. Oil breaks down the material, just as it does with latex. Stick with water-based or silicone-based lubricants.
Polyurethane Condoms
Polyurethane condoms are made from thin plastic rather than rubber. They’ve been on the market longer than polyisoprene options and have a couple of distinct advantages. The material conducts heat well, which many people say creates more natural sensation during sex. Polyurethane can also be made thinner than latex while maintaining strength.
The drawback is fit. Polyurethane doesn’t stretch the way rubber does, so these condoms don’t grip as tightly. That makes them more prone to slipping off. A systematic review of randomized controlled trials published in the journal Contraception found that non-latex condoms (primarily polyurethane in the studies reviewed) had significantly higher clinical breakage rates than latex, ranging from about 2.6 to 5 times higher depending on the study. That doesn’t mean they’re unreliable, but proper sizing and careful use matter more with this material.
A major practical advantage: polyurethane is safe to use with oil-based, water-based, and silicone-based lubricants. Oil won’t degrade the plastic the way it destroys rubber-based condoms.
Nitrile Condoms
Nitrile is a synthetic rubber commonly used in medical gloves. It’s newer to the condom market and is primarily found in internal (sometimes called “female”) condoms, though external nitrile condoms are now available too. Durex Intense is one example of an external nitrile condom currently sold in the U.S.
Like polyurethane, nitrile warms quickly to body temperature, which contributes to a more natural feel. It’s also compatible with all lubricant types, including oil-based. Nitrile provides full protection against both pregnancy and STIs.
Lambskin Condoms
Lambskin condoms are made from sheep intestinal membrane. They’re the oldest type of condom still sold and are sometimes marketed as “natural” or “sheepskin.” The material transmits heat and sensation better than any synthetic, which is why some people strongly prefer them.
However, lambskin has a critical limitation: the membrane contains tiny natural pores. These pores are small enough to block sperm, so lambskin condoms do prevent pregnancy. But viruses, including HIV, HPV, herpes, and hepatitis, are small enough to pass through those pores. If STI protection is part of why you’re using a condom, lambskin is not a safe choice.
Lambskin condoms are also the most expensive option, often costing several dollars per condom. They’re compatible with all lubricant types.
Lubricant Compatibility at a Glance
- Polyisoprene: water-based and silicone-based only (no oil)
- Polyurethane: water-based, silicone-based, and oil-based
- Nitrile: water-based, silicone-based, and oil-based
- Lambskin: water-based, silicone-based, and oil-based
If you want the flexibility to use any lubricant, polyurethane, nitrile, or lambskin all work. Polyisoprene is the only non-latex material that shares latex’s vulnerability to oil.
How to Choose the Right One
If you have a latex allergy and want the closest experience to a standard latex condom, polyisoprene is the most straightforward swap. It stretches similarly, fits similarly, and protects against both pregnancy and STIs. SKYN Original is the easiest to find in most stores.
If heightened sensation is your priority and you’re in a relationship where STI risk isn’t a concern, lambskin offers the most natural feel. Just remember it won’t protect against infections.
If you want to use oil-based lubricants and still need STI protection, polyurethane or nitrile are your options. Nitrile tends to fit more comfortably than polyurethane because it has better elasticity, though fewer product options exist in this category so far.
Regardless of material, proper sizing is the single biggest factor in whether a condom works well. A condom that’s too loose will slip. One that’s too tight is more likely to break. Most non-latex brands now offer multiple size options, so it’s worth trying a few to find the right fit.
