Hydro FlaskDown Shift Hydration Pack

I love the quality and build of this backpack. I initially was afraid to spend this much on a backpack made by a water bottle company as my experience with backpacks has always been with a reputable brand like Osprey. The Hydro Flask did not disappoint at all. The material is comparable to all of my Osprey bags and feels very premium.I love the carabiner attachment loops on the front as this is where I store my gloves and helmet when I am not using them. The loops are sturdy and of high quality stitching.The 2L water pak is made of premium materials and keeps my ice and water cold for up to 4+ hours. It is very well insulated and does not take up all of the bag storage space. I love how it sits low on the back so you don't feel it on your entire back like some hydration packs.The separator between the back and backpack keeps you AND your water from overheating while riding. This is key and a huge contributor to keeping your water cooler for longer.The hose is made of high quality material, has an ON/OFF dial and the plastic that you bite on is replaceable in case you chew on it and ruin it or happen to lose it.The strap system gives you the perfect fit whether you want it right on your torso and waist or loose.The bag has plenty of storage inside for a change of clothes, your keys, wallet, bike tools, sunglasses, an energy bar, etc.I wouldn't change this hydration pack for any other and highly recommend it for anyone on a mountain bike or just someone who loves to hike and lightweight hydration pack.

The bladder was hard to figure out how to open but otherwise very nice.

This thing is worth every penny! It’s super comfortable and feels lighter then it should be and it’s such a luxury to have cold water for my whole hike. I think there is room to put your snacks, maybe a light layer piece and sunscreen but know that there isn’t a ton of space in the backpack for a lot of things. Also, if you want a lot of water then this might not be for you since it only holds just under a gallon. But 100% would recommend for anyone. It also fits bigger girls, I weight 250 lbs and the straps fit around me so I was very happy to see it was plus size friendly.

5 L refers to the entire size of the pack, that includes all of the internal space.The bladder itself is 1.5 L. Therefore, there is 3.5 L in the bag for your supplies.

This works perfectly for day trips. I've wanted to get the weight off my back and prevent a sweaty back during day rides. This pack is perfect! Soft pouch up front that fits my oversized cell phone. Plus room for a CO2 inflator, cartridge, tools, some snacks and 2L of water. Wish I would've gone with the hip pack a long time ago!

Great item I doubted getting it but so glad I did, really great for running.

I like everything about it, couldn't find one with outer straps like this one which allows me to hook up a bike pump and or raincoat also if need. It might replace one of my USWE patriot pak lol unless i need more space...awesome lil bag.

Amazing product!!!!!! Keeps water cold for hours.
