Aer’s Travel Pack 3 (TP3) comes in two main material options: the more traditional 1680D Cordura® ballistic nylon and the X-Pac® sailcloth laminate. While both versions share the same overall design, organization layout, and dimensions, the differences lie in weight, weather resistance, feel, and price. Here’s a quick comparison of each material’s pros and cons.

Cordura® Ballistic Nylon Version

Pros

1. Ruggedness & Abrasion Resistance: Ballistic nylon has a long reputation for being tough and resistant to everyday wear and tear. It’s less prone to showing scuffs or surface scratches.
2. Familiar Feel & Look: Cordura ballistic nylon is often used in premium travel backpacks. It has a slightly smoother hand-feel and a more traditional “nylon” appearance.
3. Less Crinkle/Noise: Compared to X-Pac, Cordura ballistic nylon tends to be quieter – it doesn’t have as much of a “crinkle” or “paper-like” noise.
4. Usually Less Expensive: Typically, the Cordura version will cost a bit less than the X-Pac model.

Cons

1. Heavier Weight: The Cordura version weighs slightly more, which may matter if you’re striving for minimal carry weight.
2. Water Resistance Is Good (But Not as Good as X-Pac): Although the ballistic nylon is still water-resistant, it’s not quite as inherently waterproof as X-Pac laminates. Some water may seep through in very wet conditions if it’s not treated or sealed properly.
3. Less “Technical” Appearance: This could be a plus or minus, but some people prefer the more modern or sleek look of X-Pac.

X-Pac® Version

Pros

1. High Weather Resistance: X-Pac is a laminate material originally developed for sailcloth. It’s highly water-resistant, and often keeps contents dry longer under sustained rain.
2. Lighter Weight: The laminate construction is usually lighter than ballistic nylon, making the bag easier to carry if you’re counting every ounce.
3. Structured & Modern Look: The X-Pac laminate has a slightly stiffer structure, giving the bag a crisp shape. Many people also appreciate the distinctive grid pattern and the overall “technical” vibe.
4. Easy to Wipe Clean: Dirt and grime tend to come off easily from the laminate surface.

Cons

1. Price Premium: X-Pac is more expensive to produce; as a result, the X-Pac version of the Aer Travel Pack 3 usually costs more than the Cordura option.
2. Potential Crinkle Noise: The sailcloth construction can produce a slight “crinkle” or “rustling” sound, which some users find annoying.
3. Less Resistant to Abrasion in Some Cases: While X-Pac is very strong, repeated contact (like dragging on rough surfaces) can sometimes cause the laminate to show wear. The multiple layers are tough, but ballistic nylon can sometimes handle constant abrasion more gracefully.

Which One to Choose?

• Weight vs. Durability: If you prioritize a slightly lighter pack that offers higher water resistance and a distinctive modern look, the X-Pac version is for you. If you expect your bag to see a lot of abrasion or just prefer a quieter, more traditional carry, the Cordura version is an excellent pick.
• Budget: The Cordura model will generally be cheaper, so if cost is a factor, you’ll save money while still getting a robust bag.
• Aesthetics: X-Pac has more of a technical style and can show creases or folds more readily, while Cordura has a classic, understated texture.

Either way, both materials are very durable. It really comes down to how important weight savings, weather resistance, and that modern “technical” style are to you—and whether you’re willing to pay a premium for the X-Pac.
