  • 1.5 L hydration bladder included: Bladder connects via drinking tube routed over the shoulder for on-the-move hydration on trail runs, gravel rides, and MTB routes.
  • Built-in safety whistle on sternum strap: Emergency signaling always accessible without adding extra weight or attachment points — a critical feature for solo backcountry efforts.
  • 6-liter total capacity: Enough room for tools, tubes, nutrition, a layer, and a phone alongside the bladder for 2–4 hour efforts across all three disciplines.
  • Adjustable sternum slider: Fits S/M (31–37-inch chest) and M/L (36–44-inch chest) with a sternum slider that lets you position the harness exactly where it's most comfortable and stable.
  • Chest, shoulder, and side pockets: Multiple pocket locations keep nutrition, tools, and small items organized and accessible without opening the main compartment.

The RFP Hydration Pack is a 6-liter multi-sport vest for trail running, gravel cycling, and mountain biking. Includes a 1.5 L hydration bladder. Built-in safety whistle.

• Weight: 343 g
• Capacity: 6 liters
• Included: 1.5 L hydration bladder
• Sizing: S/M (31–37" chest), M/L (36–44" chest)
• Safety: built-in whistle on sternum strap
• Pockets: chest, shoulder, and side
• Sports: trail running, gravel cycling, MTB, hiking

Q: Does the bladder connect to a drinking tube?
A: Yes, the 1.5 L bladder connects to a drinking tube that routes over your shoulder. The tube and bite valve are compatible with most standard hydration accessories.

Q: Is this vest stable enough for mountain biking?
A: Yes — the four-way stretch materials and sternum strap stay close to your body during technical riding. The 6-liter capacity fits tools, tubes, nutrition, and a layer for longer MTB rides.

Q: What's the built-in whistle for?
A: The whistle is integrated into the sternum strap buckle for emergency signaling during solo trail runs or remote rides — always accessible without adding extra weight.

Q: How do I choose between S/M and M/L?
A: Measure around your chest at the fullest point. S/M fits 31–37 inches and M/L fits 36–44 inches. Runners typically prefer the smaller size for a tighter fit; cyclists often size up for freedom of movement.

My favorite pack.

I have three OM packs, the PFV, the Gear Vest, and this one. This one is by far the most functional and most comfortable.

Jason Wylie
Nothing better!

Orange Mud hydration vest is 100% quality and comfort all in one. Rugged and comfortable. I have 2 vests now and love them both!

Jaime
Worth it.

Got it to start doing trail runs to free my hands up. Ample pockets to fit everything you need. Would definitely buy again.

RFP hydration pack

This is the best purchase I have made in a while. Fit is perfect. Not much bouncing. Love it.

Holly Peterson-Herr
Best pack ever

This is the 6th hydration pack that I've tried in the last 10 years. Most packs sit high on my shoulders and end up cramping my neck. This one is the exception.

RFP Hydration Pack

New to running and looked at many options for hydration. So far I am very impressed with this pack. Fits great and not too bulky!

Very well designed

This vest is best yet. Well made, doesn't bounce unlike earlier versions and there are plenty of pockets. I'd buy it again.

Love the side pockets and change to the back

I have been using the RFP Hydration Pack for over a decade, but the addition of the side pockets and the change to the back has made the pack my go-to for longer runs.

The Mud, the blood, and the beer

Its still too early to tell completely but I like it so far. My only concern is that the fit will be too snug if I wear a shirt or sweat shirt when its colder.

R

Love this hydration pack!

Orange Mud knocked this one out of the park! I have a different pack that I've always loved, but I always wanted to try the RFP. It's very comfortable and fits and functions well.
