Raide Locking-Cap Flask
If you have transitioned from a vest to a running belt, there's a good chance you've also transitioned to soft flasks. There's an even better chance they had bite valves and got your shorts wet. The Locking Cap Flasks from Raide Research come with a lifetime warranty, won't get your bum wet, and you won't have to give it a second thought once it's stowed away. If one-stop shopping is your thing, a single 650 mL Locking Cap Flask is included with Raide's LF 2L Running Belt, and you can grab the 360 mL version for an even liter. Go ahead; you deserve a leak-free Locking Cap Flask, and you won't regret your decision.
- Locking cap for leak-free stowage.
- Available in various sizes to accommodate different belt and vest configurations.

Questions & Reviews

Is the 650ml soft flask compatible with a Salomon Adv Skin 5 vest?
9/24/2026
Yes, it can fit in due to the stretch of the material, but the oval-shape of the mouth could make the flask ride up if it is completely full. I would recommend a 500mL HydraPak UltraFlask for a better fit that isn't Salomon-branded.
