Custom soft flasks for wholesale orders.
*Build a standalone bottle line or add a flask to the gear you already sell.*
Vancharli Outdoor manufactures custom soft flasks for sports brands, wholesalers, and importers. The styles shown hold 250 mL or 500 mL, and we can develop other capacities to suit your project. Choose a bottle shape, drinking spout, and branding for standalone retail, or pair your flask with a vest or belt from our hydration gear range.
*Compare six styles by capacity, bottle shape, and drinking design.*
This slim 250 mL (8.5 US fl oz) flask has a food-grade TPU body, a silicone bite valve, and a tethered dust cap. It weighs approximately 30 g (1.06 oz) and folds down when empty.
This slim blue flask holds 500 mL (16.9 US fl oz) and has a short drinking spout with a clear cover. Printed markings make it easy to check the water level when filling the flask or after a few sips.
This 500 mL (16.9 US fl oz) flask features a BPA-free TPU body and a silicone bite valve. A tethered dust cap covers the mouthpiece between uses and stays attached when opened.
This 500 mL (16.9 US fl oz) style pairs a squeezable cylindrical body with a short drinking spout. It folds down when empty and fits into fitness and everyday sports bottle collections.
This 500 mL (16.9 US fl oz) flask has a blue-to-lime gradient, a foldable body, and a short drinking spout. Its broad front panel gives you room for a prominent logo.
This translucent 500 mL (16.9 US fl oz) flask has printed volume markings and a short drinking spout with a clear cover. A woven loop at the neck makes the flask easy to pick up.
*Confirm capacity, materials, components, and branding before approving your sample.*
Tell us the capacity you need, and we can develop a flask around that target. A slim body is a good starting point for a narrow vest pocket, while a cylindrical profile can suit a standalone fitness range. For a vest or belt bundle, share the pocket opening and depth so we can check the filled flask against the intended holder during sampling.
Specify the bottle body material and any food-contact requirements early in the project. The 250 mL compact style uses a food-grade TPU body. The 500 mL bite-valve style shown as product 3 uses a BPA-free TPU body. If you need material documentation, share the destination market and specify which components it should cover, such as the body, cap, valve, or seals.
Choose from compatible bite valves, drinking spouts, caps, and other fittings for your selected soft flask model. Multiple styles are available, and component colors can be customized to match your product line. These accessories are supplied only as part of a soft flask order.
Match the bottle color and logo placement to your collection. If the design includes volume markings, check the placement and readability of both the logo and markings on a filled sample. Confirm the sales format early so the packaging suits an individual flask, a multipack, or a vest-and-flask set.
*Develop the flask around how your customers will carry, use, and buy it.*
Two soft flasks can hold the same amount of water and fit very differently in a running vest. At Vancharli Outdoor, we look at how the flask will be used, what gear it will be paired with, and how you plan to sell it. Those details guide the choice of flask, the sample review, and the final order specifications.
Start with a reference style or share a brief with your target capacity, carry method, and branding requirements. We can use those details to identify a suitable starting point for development.
We check how the filled flask sits in the intended vest pocket or belt holder. This helps catch issues such as a cap that sits too low or a bottle shape that is awkward to slide back into the pocket.
Review the body, cap, and valve together on one assembled sample. Check the finished dimensions, how the cap opens, and where the logo sits when the body is filled.
For a standalone retail flask, plan the branding around how the bottle will look on the shelf. For a vest or belt bundle, coordinate the flask’s colors and artwork with the rest of the set.
Confirm the model, components, print, and packing details before production. Your buying team can refer to the approved specifications when reviewing the finished order.
*Six design details that affect carrying, drinking, and refilling.*
The flexible body takes up less space as the flask empties and folds down for storage after use.
On selected styles, a protective cover helps keep dust and dirt off the mouthpiece between uses. A tethered cover stays attached to the flask when opened, so users can close it again after drinking.
Slim, cylindrical, and broader profiles give buyers options for different pocket shapes, carry setups, and retail collections.
A silicone bite valve lets users sip from the flask without unscrewing the main cap.
Compatible spouts and fittings vary by flask model. On a vest-mounted flask, the spout’s height and angle affect how easily the runner can reach it while the flask sits in the pocket.
Printed graduations provide a quick reference when refilling the flask or checking how much water remains.
*Match each flask to the way it will be carried and used.*
A compact 250 mL flask works well in a minimalist running kit or a race bundle. If the kit includes a hydration belt, check whether the runner can take the flask out and put it back without readjusting the belt.
A 500 mL flask gives runners more water per pocket. For a vest designed for in-pocket drinking, check where the mouthpiece sits when the flask is full and again when it is partly empty.
A collapsible flask can serve as a second bottle on day hikes and fold down after use. For a day-pack bundle, check whether the side pocket holds the flask securely once it is partly empty.
A cylindrical style suits a fitness bottle range, while the gradient style gives branded artwork a colorful backdrop. For standalone retail, review how the logo looks on a filled flask and how the bottle will be displayed in its packaging.
*We check production details against the approved sample and order specifications.*
We verify the bottle body material, cap, valve, and any specified seals against the approved configuration. When the order calls for material documentation, we check that it covers the relevant components.
We inspect the welded seams, base, and shoulder for visible defects and compare the finished shape with the approved sample.
We verify the agreed fill capacity and key dimensions. For flasks paired with a vest or belt, we check measurements such as the overall height with the cap fitted and the width when filled.
We check that the cap seats correctly and that the drinking valve and protective cover work as intended on the selected style.
We check the body seams, bottle neck, and drinking assembly for leaks using the inspection method agreed for the order.
We compare the logo, volume markings, and color with the approved sample, then verify the labels, packing quantities, and contents of any bundled sets.
*Answers to common questions about materials, fit, customization, and bulk orders.*
The styles shown hold 250 mL (8.5 US fl oz) or 500 mL (16.9 US fl oz). We can also customize capacity for wholesale orders. Share your target volume and any size limits if the flask needs to fit an existing vest pocket or belt holder.
Product 3, the 500 mL style with a silicone bite valve and tethered dust cap, has a BPA-free TPU body. If your specification also covers the cap, valve, or seals, list those parts when requesting material documentation.
The 250 mL compact flask shown as product 1 uses a food-grade TPU body. For orders with specific food-contact requirements, share the destination market and the components your documentation needs to cover.
Fit depends on the flask shape and the pocket or holder design. Share the opening width and depth, or provide a reference sample. We can check how the filled flask sits and whether the mouthpiece is easy to reach.
Yes. Share your logo artwork, preferred placement, and the graduations you need. We can check the print size and readability on a sample of the selected style.
You can order complete soft flasks on their own or bundle them with a vest or belt. For a bundled order, specify the flask style, how many flasks go in each set, and how the set should be packed for retail or distribution.
Yes. Use the sample to check the filled shape, cap operation, and fit with your gear. For a private-label order, confirm which color, print, and packaging details you want to see on the approval sample.
Custom soft flask orders typically start at 500 pieces. Share your preferred style, colors, and packaging requirements so we can confirm the MOQ for your order.
Lead times depend on the bottle configuration, artwork approval, packaging, and order quantity. For a vest or belt bundle, the schedule also includes time to approve the fit and packing of the assembled set.
Follow the care instructions for the selected model. After use, empty and rinse the flask and mouthpiece, then leave the cap off and let the parts air-dry before storing. For private-label orders, care instructions can be reviewed when you approve the packaging or insert.
