Perfect
I bought this model because I like a hip pack, but the quality far exceeds the other brand that starts with an o. I love the long magnet. Super important to feel secure in the fastening when the hose is that long!

Excellent product
Perfect size for 2-3 hour rides. Holds a lot of stuff, including my rain jacket. Plenty of pockets to keep your supplies organized.

Exactly what I needed
Great hip pack. I never ride with a backpack, but I am doing longer rides and needed a little extra space. This pack is perfect. Low profile if I need it, but enough room to stuff my rain jacket if needed. It is the perfect mix between 2 water bottles and some tools on the bike, and a full hydration backpack!

Phone pocket is great
I didn't expect the phone pocket to be that useful, but even with the pack totally stuffed, I can easily put my phone in and out while still on the bike. I also like that now it isn't a choice of when I have my phone in my pocket, do I face the screen out and risk breaking it in a fall or do I face it in to protect it, but then risk a pocket dial as it gets sweaty. The pocket takes that out of the equation and is a feature I didn't realize I wanted.

Great Pack!!
I recently purchase the Rail 2L pack after reading a review in MBA. I had been looking to move away from carrying gear on my back especially water I order to lighten my ride. The Rail 2L is light and comfortable. It can carry any needed tools, a light jacket and trail snacks along with 2 water bottles. I’ve used it on 4 or 5 rides now don’t plan to go back to the backpack style of carrier. Thule Rail 2L is a great pack!

Thirst Quencher!
Great product, a well thought out hydration hip pack with ample storage and a ton of adjustability. The magnetic hose is next level.

Didn’t know I needed a hip pack until I used this!
Rode some downhill laps with this and it worked great. Phone is easy to access in the padded zipper pocket. Holds the perfect amount of water without being too heavy with a multi tool and a couple co2 canisters. The waist belt is comfortable and kept the Rail 4 in place on rough terrain in Utah.

Functional water pack for biking
The 4L pack is functional with multiple pockets to store all the things you'll need while out on a ride. I love that the pack comes with a 1.5L bladder, and the phone pocket is easily accessible and secure. Like the product, but probably would have gone a size down in hindsight, the 4L is quite big!
