How to choose
Decision guide
Handhelds, soft flasks and reservoirs — choose carry format by volume, bounce and distance.
Product types
- Handheld. Simple short/medium carries.
- Soft flasks. Vest/belt compatible volume.
- Reservoirs. Higher volume for ultra/adventure days.
What matters
- Volume for your longest session without aid
- Bounce and bounce control
- Whether you also need soft flasks in a vest
Specs that matter
- Capacity. Match distance and heat, not Instagram kits.
- Bite valve / cleanability. Hygiene and flow reliability.
Common trade-offs
- Vest volume ↔ Belt simplicity. Belts win phone+gels; vests win flask + jacket storage.
When use case changes the choice
- Road long <2h. Handheld or belt often enough.
- Trail ultra. Vest + soft flasks become default.
Beginner start
Start with a handheld or simple belt. Move to a vest when you regularly carry >500 ml plus layers.
