Top TSA-Approved Quart-Size Toiletry Bags
Why a TSA-Compliant Quart-Size Bag Matters
The Transportation Security Administration (TSA) requires all liquids, gels, creams, and aerosols in carry-on luggage to be in containers **3.4 ounces (100 mL) or smaller and packed into a single, clear, quart-size bag**. A good bag here isn’t just about passing security—it’s about **durability, leak resistance, and usability in tight travel situations**.
> Fact check: TSA defines “quart-size” as approximately 7” × 8” (18 × 20 > cm), though minor variations are typically allowed.

Key Features to Look For
1. True TSA-Approved Dimensions
- Stay under 1 quart (946 mL) capacity. - Fully clear body for quick visual inspection. - Avoid oversized "cosmetic bags" that may cause secondary screening.
2. Leak-Proof Zippers & Seals
- PVC or TPU material for waterproofing. - Double-sealed zippers reduce the risk of liquid leakage.
3. Durable, Flexible Material
- TPU: more eco-friendly, UV-resistant, and less prone to cracking in cold conditions. - PVC: affordable but can stiffen over time.
4. Structured vs. Unstructured
- Structured: Keeps bottles upright, reduces leaks. - Unstructured: Packs flatter, better for ultralight travel.
5. Ease of Cleaning
- Wipe-clean interiors for spills. - Rounded corners prevent liquid buildup.

Common Mistakes to Avoid
1. Overstuffing — TSA agents must be able to seal the bag; a bulging zipper can lead to a manual bag check. 2. Using opaque pouches — Will likely trigger extra screening. 3. Bringing full-size products — Even if under quart size, 150mL+ bottles will be confiscated.
