ThuleUnisex's Rail Hydration Pack

awesome bag , light weight, very spacious 1❤️❤️❤️

Both me and my husband are avid cyclists (like many in San Diego thanks to our great weather and environment). We are biking way more than before with this whole Covid situation. we both have mountain bikes, beach cruisers and also road bikes, so basically half our garage is bikes.If you know Thule, you know none of their products are ever bad, they do an excellent job designing and manufacturing their products. This one is another one their great products.The most important feature of this back pack obviously is the vertical pouch inside that allows you to carry the extra battery for your e-bike. Most older models have smaller batteries and instead of paying arm and a leg to upgrade, you can just get this back pack and add more juice to your e-bike. Just keep in mind that the pouch is barely 15" deep and anything larger than that won't fit in there. It has a hook and a loop and some straps to really fit the battery in place and fix it so that it won't move around when riding. If you use a relatively large battery to fill the pouch, it should be very very stable, if you use something very small, I can see how it might wobble a little bit in there.Like all other backpacks, it has multiple storages pouches and compartments for snacks and spares and ... 18L is a lot of room so you'll be able to fit everything you need in there, very very high capacity. tools, hand pump, inflator, gauge, food, jackets ... can all go in there if properly placed.We usually use the outside pockets for food and snacks though, there are two pockets in front that have enough room for small snacks and there are two zipper pockets on the back of the rail that you can put cell phones, car keys or more valuable stuff.The hydration compartment (water reservoir) is 2.5L which is equal to 5 regular Costco water bottles. The hose is magnetically connected to the right shoulder strap and is pretty firm and holds well in place.There's a damage control system on the back that is supposed to absorb the impact on your back and make it slow and disperse. It works very well, very light and effective. However, I've heard from friends that if you get into a hard impact, you'd have replace it because its energy absorption system destroys with a big impact to save your back. luckily it hasn't happened to me yet but sure how it needs to be done if needed.It is very comfortable and very adjustable. it does fit and strap very well but remember, with the extra battery and water, you're probably looking at an extra 20lbs minimum so expect some weight on your back. We don't do serious mountain biking but I can see even on small falls, the weight on my back is noticeable. Let alone a jump, I can see if one jumps with this, the weight difference can cause some balance issues and you have to do it slowly to earn experience jumping with this on your back. Don't do a big jump first time you use this or it might throw your balance off.The price is obviously a little high but you're getting a name brand that is well known and is very reliable. Overall, a great product specially if you need to carry extra battery for your mountain e-bike. Very very comfortable and great design and nice features.

I am a huge fan of Thule and own many products manufactured by the company. You know you are going to pay a premium when you purchase the Thule brand, but the quality you receive never fails to disappoint! This backpack is no exception! I also own the Thule Rail Hip Pack and it is equally as impressive!PROS:(1) The magnetic strip which secures the hose is the best solution I've ever seen by any manufacturer. The hose grips perfectly to the magnetic strip every single time, with virtually no effort by the user. With this system, you can easily grab a drink with just one hand while hiking or riding your bike.(2) The bladder is large and made of a durable material which should last for years without leaking. It is easy to clean.(3) Despite being compact in size, this backpack has a ton of storage space for all of your personal items, even when the bladder is full. There is plenty of room to fit a jacket, change of clothing, cell phone, keys, wallet/purse, hairbrush, glasses, and snacks along with the filled bladder. (4) The item description does not mention water resistance, but I briefly ran the pack under my kitchen faucet and it held up well, with no water escaping into the compartments. It should do well in light to medium rain situations. In addition, it comes with a removable rain cover which adds a second level of protection if the weather turns very unfavorable.(5) The materials used to construct this pack are all very durable and should last for years, with normal use.(6) I am 5'4", 155 pounds. My husband is 6', 250 pounds. We both found this pack comfortable to wear. For those who suffer from back problems a removable Level 1 back protector is available.(7) STABILITY - This bag does not move once it is properly secured. You will never have to worry about it coming loose or falling off.Unlike most products that I review, I don't have any CONS to list about this backpack. Thule really thought of everything when they made this product. There's even a dedicated spot for a spare battery for those who use e-bikes! Overall, you can put your trust in this Thule backpack just like you do in all Thule products. It's a great addition to the Thule line.
