zhàngpeng fángshuǐ.

• 帐篷 = zhàngpeng
  • zhàng: fourth tone, falling
  • peng: neutral tone here, so it is light and unstressed
• 防水 = fángshuǐ
  • fáng: second tone, rising
  • shuǐ: third tone

A natural rhythm is:

zhàngpeng fángshuǐ

The main stress is usually on zhàng and fángshuǐ, while peng is lighter.

In Mandarin, words describing a quality often act like verbs in the sentence, so you usually do not need 是.

So:

• 帐篷防水。 = The tent is waterproof.

Compare:

• 他很高。 = He is tall.
• not usually 他是高。

With 防水, Chinese treats it as a property the tent has, so 是 is often unnecessary.

A more expanded version is possible, such as:

• 这个帐篷是防水的。

But the short sentence 帐篷防水 is completely normal, especially in product descriptions, labels, or concise statements.

For learners, the easiest way to think of 防水 here is: it works like an adjective, meaning waterproof.

But Chinese grammar does not match English grammar exactly. Many words that translate as adjectives behave more like stative verbs in Mandarin.

So in:

• 帐篷防水。

防水 is the predicate of the sentence, meaning the tent is waterproof.

You do not need a separate verb like is.

Learners often notice sentences like:

• 他很高。

So they wonder whether this should be:

• 帐篷很防水。

Usually, 很防水 is not the most natural basic way to say it.

That is because 防水 is more of a functional property or product feature than a simple descriptive adjective like 高 or 漂亮.

So these are natural:

• 帐篷防水。
• 这个帐篷防水。
• 这个帐篷是防水的。

很防水 can appear in some contexts, but it sounds more like very waterproof and is less neutral.

It can be a complete sentence, but it sounds especially natural in product descriptions, ads, labels, or short factual statements.

For example, on packaging or in a sales context, Chinese often uses very concise wording:

• 帐篷防水。
• 外套防风。
• 鞋子防滑。

In everyday conversation, people might also say:

• 这个帐篷防水。
• 这个帐篷是防水的。

Those feel a little fuller and more conversational.

You may have seen:

• 这个帐篷是防水的。

Here, 的 helps turn 防水 into a descriptive attribute in a very natural way.

But in short predicate sentences, especially concise statements, Chinese often leaves 的 out:

• 帐篷防水。

Both can be correct, but they feel slightly different:

• 帐篷防水。 → short, direct, factual
• 帐篷是防水的。 → a bit fuller, more explicitly descriptive

So 的 is not required in this short structure.

Mandarin usually follows a topic/subject + comment/predicate pattern.

So:

• 帐篷 = the tent
• 防水 = waterproof

Together:

• 帐篷防水。 = As for the tent, it is waterproof.

This is the normal order in Chinese: first say what you are talking about, then say something about it.

It can mean either, depending on context.

Chinese nouns usually do not show singular vs. plural the way English does.

So 帐篷 could mean:

• the tent
• a tent
• tents / tents in general

In this sentence, the exact meaning depends on the situation:

• on a product tag: probably this tent is waterproof
• in a general statement: possibly tents are waterproof

If you want to be more specific, you can add words like:

• 这个帐篷 = this tent
• 那些帐篷 = those tents
• 一个帐篷 = one tent

A common measure word is:

• 顶

So:

• 一顶帐篷 = one tent
• 两顶帐篷 = two tents

This is useful when you want to count tents.

帐篷 防水 uses:

• 帐篷 = simplified
• 防水 = same in both simplified and traditional

The traditional form of 帐 is:

• 帳篷

So:

• Simplified: 帐篷防水。
• Traditional: 帳篷防水。

The pronunciation and meaning stay the same.

Yes, you can absolutely say:

• 帐篷是防水的。

Both are correct, but they have different style/feel:

• 帐篷防水。 → shorter, more direct, more like a feature statement
• 帐篷是防水的。 → fuller, more explanatory, often more natural in careful speech

If you are describing product features, 帐篷防水 is very natural.

If you are answering a question or speaking more fully, 帐篷是防水的 is also very common.

Yes: the second syllable peng is usually neutral tone in 帐篷.

That means you should not pronounce it with a strong full tone like péng in careful dictionary-style isolation unless your teacher specifically teaches that variant. In everyday speech, it is commonly lighter:

• zhàngpeng

Also, make sure zh is pronounced as a retroflex sound, not like English z.

So try:

• strong falling tone on zhàng
• light, quick peng

Yes, especially in the right context.

Chinese often allows very compact sentences when the meaning is obvious. For example:

• 衣服防水。 = The clothes are waterproof.
• 手机防水。 = The phone is waterproof.
• 这双鞋防滑。 = These shoes are slip-resistant.

So 帐篷防水。 sounds natural if you are describing the tent’s feature.

If the context is less clear, a speaker may add more words, such as:

• 这个帐篷防水。
• 这个帐篷是防水的。

Both simply make the sentence more explicit.
