6 Best Leakproof Seals For Travel That Actually Work
Stop messy spills in your suitcase with these 6 best leakproof seals for travel. Read our expert guide to find reliable solutions and pack with confidence today.
A leaking water bottle or a spilled bottle of delicate wool wash can ruin a project bag in seconds. For those who travel with expensive hand-dyed yarns or delicate lace projects, the integrity of a container is just as important as the quality of the needles. Choosing the right seal means moving beyond generic kitchen storage toward equipment built for pressure and movement. Here are the most reliable solutions for protecting fiber arts supplies on the move.
Stasher Silicone Bags: Best for Wet Projects
Silicone bags offer a flexible, puncture-resistant alternative to flimsy plastic bags. The patented pinch-lock seal provides a surprisingly airtight closure that withstands the jostling of a carry-on bag.
These bags excel when transporting wet blocking mats or damp, freshly washed swatches that need to travel before drying. Because they are heat-safe, they can even be used to hold a project while steaming or blocking in a pinch.
Be aware that these bags are heavy compared to traditional zipper-top storage. They are best suited for smaller items or specific tools rather than an entire sweater quantity of bulky wool.
Zojirushi SM-KHE Travel Mug: The Ultimate Seal
The Zojirushi mug features a locking mechanism that creates a genuine vacuum seal. It is the gold standard for carrying liquid wool wash or even a small amount of tea while knitting in transit.
When the lock is engaged, the lid cannot pop open even if it gets buried under a heavy project bag or a stack of circular needles. This level of security is unmatched by standard sport bottles that rely on simple friction-fit caps.
While it is an investment, it eliminates the risk of catastrophic spills near delicate, untreated fibers. For the knitter who requires a caffeine boost while working on intricate colorwork, this represents total peace of mind.
humangear GoTubb: For Notions and Wool Wash
GoTubbs are designed for easy, one-handed access, which is ideal when knitting in tight spaces like an airplane seat. The pop-open design is surprisingly secure and keeps stitch markers and measuring tapes organized.
These containers work exceptionally well for small portions of specialty soaps used for soaking fibers during a trip. The lids are designed to stay shut under normal pressure but are not meant for long-term submersion.
Use these for notions and dry items, as the seal is not designed for vigorous shaking with liquids. They are the perfect size for carrying a few spare tapestry needles or a folding pair of embroidery scissors.
Nalgene Leakproof Jar: Best for Bulk Liquids
Wide-mouth Nalgene jars are the workhorses of the travel world for a reason. The heavy-duty threads on the cap ensure a seal that is essentially impossible to break by accident.
These jars are the best choice for storing larger quantities of wool wash or liquid detergents. Their thick walls prevent them from cracking even when packed into a crowded suitcase full of needles and notions.
If space is at a premium, look for the smaller, short-profile versions. These fit easily into a project bag’s side pocket while still providing the heavy-duty protection necessary for liquid supplies.
Unwasted Silicone Lids: Seal Any Container
Silicone stretch lids offer a versatile way to turn any existing mug or small bowl into a travel-ready container. They are highly elastic and grip the edges of rigid surfaces firmly to create a suction seal.
These are particularly useful for knitters who reuse containers to hold supplies while traveling. They effectively cover odd-shaped items that don’t have a matching lid, keeping dust away from yarn.
Do not rely on these for pressurized environments or items that will be inverted for long periods. They are best for upright storage during commutes where accidental splashes are the primary concern.
Sea to Summit Dry Sack: Protect Your Projects
A dry sack is constructed from waterproof fabric with a roll-top closure to keep contents completely dry. It acts as an insurance policy for a hand-knit project, ensuring that external water cannot reach the fibers.
If traveling to damp climates or participating in outdoor knitting retreats, this is a necessary layer of defense. It protects yarn from rain, humidity, and the potential spills of others in a communal knitting space.
While highly effective, remember that these bags trap moisture inside as well as out. If a project is even slightly damp when sealed, ensure it is removed as soon as you reach your destination to prevent mildew.
How to Pick the Right Seal for Your Project Bag
When choosing a seal, evaluate the contents first. Dry notions require quick access, while liquids require mechanical locking mechanisms.
- For notions: Prioritize speed of access, such as the GoTubb.
- For liquid wash: Prioritize locking seals, such as Nalgene or Zojirushi.
- For project protection: Prioritize fabric integrity and water resistance, such as the Dry Sack.
Avoid settling for basic sandwich bags, which can easily tear when catching on the sharp points of bamboo or metal needles. The initial cost of a high-quality seal is negligible compared to the cost of replacing a project ruined by a leaking soap bottle.
Silicone vs. Hard Plastic: Which is Better?
Silicone is pliable and resilient, making it better at absorbing the impacts that occur inside a busy project bag. It is less likely to crack than hard plastic, but it can be more prone to picking up lint and dust from yarn fibers.
Hard plastic, such as that found on a Nalgene or Zojirushi, offers a more reliable, permanent seal for liquids. It is easier to clean and sterilize, but it can be brittle if dropped against a hard surface like an airplane floor.
Choose silicone when you need versatility and shock absorption for delicate items. Choose hard plastic when you need an absolute, leakproof barrier for liquids.
Keeping Your Seals Clean and Truly Leakproof
The most common cause of a “leakproof” failure is actually debris trapped in the seal. Even a single strand of mohair or a speck of dust can create a channel for liquid to escape.
Regularly inspect the gaskets of your travel containers. If a seal looks flattened or shows signs of wear, replace it immediately to maintain the integrity of the unit.
Wash all containers with mild soap and warm water, but avoid harsh abrasives that could scratch the sealing surfaces. Always dry the seal completely before closing the lid to prevent the growth of mold or bacteria inside the container.
Pro Tip: Preventing Leaks on an Airplane
Air pressure changes during flight can cause air trapped inside a container to expand, forcing liquids to push past a seal. To mitigate this, always leave a small amount of “headspace”—a pocket of air—at the top of any liquid container.
For extra security, place your liquid-containing jars inside a secondary Ziploc bag. This provides a final layer of protection if a container fails during the pressure changes of takeoff and landing.
If you carry specialized wool wash, consider transferring it to the smallest container possible to reduce the volume of air that expands during the flight. Minimizing the contents relative to the container size is the best way to ensure your bag stays dry.
Investing in high-quality storage is the final step in ensuring your hand-knits arrive at their destination in the same condition they left your needles. By selecting containers that match the specific risks of your travel environment, you protect both your time and your materials. Proper care and smart packing habits will keep your project bag safe, dry, and ready for your next knitting adventure.
