Finding the right hydration system for you can be a bit of a dating game: Between handheld bottles, belts, and vests, there are plenty of options—but depending on how, when, and where you run, finding the one that works best for you can take some trial and error.

These are six of our favorite hydration products that we tested this season to keep you fueled on your next run. Seriously, don’t leave home without one.

Hydration Vests

SALOMON ADVANCED SKIN 8 SET

SALOMON ADVANCED SKIN 8 SET
Made specifically to fit a woman’s body, this vest comes with two 500ml Hydrapak soft flasks that sit comfortably beneath (and slightly to the side of) your chest; a new lacing system eliminates pressure on your girls when the vest is synched down, keeping you feeling balanced and comfortable no matter how many miles you’re tackling. $145, rei.com

LULULEMON ENLITE HYDRAFFINITY VEST
This new vest combines the convenience of run-ready hydration with the support of a high-performance bra. Guided by the same research that created the brand’s popular Enlite Bra, it features a back pocket that holds a 1.5L reservoir, as well as three-dimensional cups and taped seams to create a secure and comfortable fit that reduces bounce and chafing. $178, lululemon.com

Hydration Belts

Camelback Ultra Belt

CAMELBAK ULTRA BELT
This sleek belt is made of a flexible, breathable mesh; it stores a 17-ounce soft hydration flask that molds to the shape of your body, while an extra stretch pocket keeps gels, money, and keys safely tucked away. $55, camelbak.com

NATHAN TRAILMIX PLUS INSULATED 2 HYDRATION BELT
The brand’s best-selling belt just got an impressive update—now featuring two 10-oz insulated flasks to keep water cooler, longer, while keeping the same comfy, bounce-free waist position and zip pocket (that fits an iPhone 7 Plus!) from the previous model. $65, amazon.com

Handheld Bottles

HYDRAPAK SOFTFLASK 500MLHYDRAPAK SOFTFLASK 500ML
Short runs, travel runs, as a spare bottle on longer outings—this one comes with us everywhere. The soft bottle conforms to your hand and shrinks as you drink, reducing water movement on the run—plus it’s then super easy to crumple up and stash away in a waistband or pack when you’re done with it. $20, rei.com

AMPHIPOD HYDRAFORM FLASH HYDROSTROBE MINIMALIST 12OZ.

AMPHIPOD HYDRAFORM FLASH HYDROSTROBE MINIMALIST 12OZ.
Handhelds are a perfect hydration system when you’re heading out for a quick 30- or 45- minute run. This one’s especially clutch if you’re heading out at dawn or dusk. The patented ergonomic bottle design fits perfectly in the palm of your hand, with a soft and adjustable hand strap to reduce hand fatigue. Integrated LED lights in the sleeve turn on with the click of a button for added visibility on the road or trail in low-light hours. $29, amphipod.com
