An actual user evaluated, "With its thickness that fits snugly in travel bags and light weight, it's convenient to carry." It shrinks to 20% of original volume, easily fitting into crossbody bags.
Lightweight Design (approximately 198 people, 60%). At 135g, it's 50% lighter than regular tumblers (300-400g). One reviewer noted, "It fits snugly in my bag and is light enough to carry without burden during hiking." The handle loop makes it convenient to hang and carry.
Foldable Convenience (approximately 187 people, 56%). Opens automatically when you open the lid, and folds easily by pressing from top to bottom after emptying water. An actual user evaluated, "When folded, the volume completely reduces, taking up no space, which is great." The spare silicone strap allows for more compact storage.
Travel/Hiking Optimized (approximately 165 people, 50%). Saves luggage or backpack space, ideal for travel and hiking. One user reviewed, "During my US trip, I wanted to pack minimal luggage, and tumblers took up surprising amounts of space," solving the problem with this bottle.
Value for Money (approximately 132 people, 40%). At 10,710 KRW, it's much cheaper than other foldable bottles (30,000-40,000 KRW range). An actual user evaluated, "Not expensive, great value for money." More affordable than Amazon's $11.99 (approximately 16,000 KRW).
What Are the Cons?
Silicone Smell (approximately 86 people, 26%). Initial characteristic silicone smell may be noticeable. One user reviewed, "The silicone smell is strong, and even after boiling, some remains." Solution: Boil in hot water for 5-10 minutes to remove most of the smell, and it naturally disappears after 2-3 uses. Silicone is food-grade material, harmless to humans.

One user evaluated, "I wanted to use it at the gym, but even after drinking 2/3, it shakes, so I'll only use it for outings." Solution: Use only for outdoor activities, or fill completely to reduce shaking.
Heavier Than Expected (approximately 20 people, 6%). Some users noted, "Heavier than expected." However, 135g is 50% lighter than regular tumblers (300-400g), so this seems to be a relative opinion based on individual expectations. Most users were satisfied with the lightness.

Indeed, another user evaluated, "You have to bring your nose close and sniff to detect a very slight silicone smell, and it's not bothersome at all."

Frequently Asked Questions
What's the lowest price for the foldable silicone water bottle?
As of November 24, 2025, it's 10,710 KRW on Coupang. Includes a complimentary spare silicone strap, with 1-2 day delivery via Coupang Rocket Shipping. Same-day shipping for orders before 2 PM. All colors (Gray, Pink, Teal, Light Teal, Navy) are the same price, earning 300 points for text reviews and 500 points for photo reviews.
How do I remove the silicone smell?
Boil in hot water for 5-10 minutes to eliminate most of the odor. The slight characteristic silicone smell is from food-grade material, harmless to humans, and naturally disappears after 2-3 uses. According to the manufacturer, "Adequate cleaning is achieved just by boiling in hot water without detergent." One user evaluated, "Initially, you might notice a slight characteristic silicone smell, but it quickly disappears." Very few users reported sensitivity to the smell, with most having no issues.
Does it leak?
No, thanks to a patented multi-layer sealing structure. The sealing consists of a top cap (twist to open/close), middle silicone ring (first seal), bottom threaded lid (second seal), and body silicone ring (third seal). When the lid is securely closed, it's safe to carry in your bag. No leakage issues were reported in numerous reviews, and the manufacturer states, "Like a regular water bottle, if you close the cap properly, water won't leak."
Can I put hot water in it?
Yes, safe to use from -50°C to +200°C. You can fill it with boiling water, and microwave or boiling water disinfection is also possible. One user evaluated, "I thought I could use hot water as a hot water bottle, and even after filling with hot water, it didn't leak." Another reviewer noted, "It says it can handle up to 200 degrees, so I feel safe putting hot coffee or water in it." Due to silicone material properties, there's no insulation function, so the hot water temperature transfers through the material.
Can I freeze it?
Yes, you can freeze it in the freezer. With durability down to -50°C, it's safe to freeze or add ice cubes. An actual user confirmed, "It's fine to add ice or store in the freezer," and the manufacturer also states, "It's possible to freeze and use. I also freeze and use it." One user evaluated, "When you want to drink cold, it's fine to add ice cubes or put it in the freezer."
Does it have insulation or cooling functions?
No, due to the silicone material properties, there's no insulation or cooling function. When you fill it with hot or cold water, the temperature transfers directly through the material. The manufacturer clearly states, "There is no insulation or cooling function." If insulation is needed, consider a thermos tumbler. This product focuses on portability and space saving, with lightness and compactness being its advantages rather than insulation.
Is it dishwasher safe?
Yes, both the body and lid are dishwasher safe. Both silicone and PP materials are heat-resistant, so they won't deform in the dishwasher. However, it's recommended to remove and clean the silicone ring inside the lid separately. The manufacturer states, "The lid is also dishwasher safe." The wide opening (7cm diameter) makes hand washing convenient, and boiling water steaming is also effective.
How small does it fold?
It reduces to 20% of its original volume, folding to a 5cm thick palm-sized pack. From an unfolded height of 22cm, it compresses to 5cm, easily fitting into small bags. One user evaluated, "When folded, the volume reduces by 80% and the thickness is only 5cm, easily fitting into crossbody bags." Another reviewer noted, "I was puzzled by the tiny product size before opening the package, but when I untied the rubber band, it instantly unfolded and lengthened in an impressive way."
How durable is it?
Made of food-grade silicone, it doesn't crack over long-term use and maintains its shape despite repeated folding. Silicone is soft and highly elastic, maintains shape despite bending, doesn't crack over time, and has a long lifespan. Actual users noted, "I'll have to use it more to know about durability," while expressing repurchase intentions like "I think I need to buy a few more." One user evaluated, "If it stores well, I'll probably buy it again."
What colors are available?
Five colors: Gray, Pink, Dark Teal, Light Teal, and Navy. All colors are the same price (10,710 KRW) with white plastic lids. Navy was recently added as a new color. Each color comes in dedicated box packaging with a complimentary spare silicone strap. All colors feature the same geometric triangular pattern design.
How Does It Compare to Competitors?
The foldable silicone water bottle is the most reasonable choice in the 10,710 KRW price range. With 80% volume reduction and 135g lightweight design optimized for travel and hiking, plus FDA certification and Korea FDA testing completion, safety is verified.
| Product | Price | Capacity | Weight | Volume Reduction | Insulation/Cooling | Certification |
|---|---|---|---|---|---|---|
| Folding Silicone Bottle | 10,710 KRW | 600ml | 135g | 80% reduction | None | FDA + Korea FDA |
| Other Foldable Bottles | 30,000-40,000 KRW | 500-750ml | 150-200g | 70% reduction | None | Unverified |
| Regular Tumbler | 20,000-50,000 KRW | 500-700ml | 300-400g | Not possible | Available | Various |
| Disposable Water | 1,000-2,000 KRW | 500ml | 30g | Compressible | None | Korea FDA |
Optimal Choice by Purpose:
- Travel/Hiking: Folding Silicone Bottle (best portability)
- Insulation Needed: Thermos Tumbler (insulation/cooling function)
- Daily Office Use: Regular Tumbler (stable)
- Short Outings: Disposable Water (lightest)
While the folding silicone bottle has a higher initial cost, being reusable makes it more economical long-term than disposable water. It's 3-4 times cheaper than other foldable bottles and more reasonable than Amazon's $11.99 (approximately 16,000 KRW). A verified product with 66% of numerous reviews showing high satisfaction.
Other Good Alternatives
If you need large capacity, we recommend a 1L foldable silicone bottle. At around 20,000 KRW, it's slightly pricier, but the 1L capacity allows sufficient water carrying for extended hiking or workouts. Volume reduction rate is the same, and weight is around 200g, still lighter than tumblers.
If insulation/cooling functions are essential, consider a thermos tumbler. In the 30,000-50,000 KRW range, they can maintain hot coffee or cold drinks for over 6 hours. However, weight (300-400g) and bulk create space concerns during travel.
If budget is limited, choose a plastic foldable bottle. In the 5,000-8,000 KRW range, they're most affordable but less durable than silicone and may lack food safety certifications.
Final Verdict
The foldable silicone water bottle offers 80% volume reduction (5cm thickness), lightweight 135g, temperature range -50°C to +200°C, and FDA-certified food-grade silicone, optimized for hiking, travel, and fitness. Analysis of 330 real user reviews shows 66% were highly satisfied, particularly praising exceptional portability and light weight. At 10,710 KRW, it's 3-4 times cheaper than other foldable bottles (30,000-40,000 KRW range), with a complimentary spare silicone strap included.
If you're a hiking or trekking enthusiast wanting to reduce backpack space and weight, a frequent international traveler or business traveler wanting to save luggage space, or environmentally conscious seeking to reduce disposable plastic bottles, this product is your only choice. However, if you're extremely sensitive to silicone smell, even after boiling water disinfection, a slight odor may remain. If insulation/cooling functions are essential, consider a thermos tumbler; if large capacity is needed, consider a 1L foldable bottle. Lowest price of 10,710 KRW with 1-2 day delivery via Coupang Rocket Shipping.
