Love the color. It is also perfect for my daughter. I have had a hard time finding one that the straps could since up and not be too big for her. She is 70 lbs and is 4'9". It fits me perfectly as well. We had trouble at first with the water bladder leaking. The company contacted me by email after leaving a less than 5 star review due to being disappointed with the hydration bladder leaking. They immediately sent me another hydration bladder. We have used it a few times over the past week and so far it is great. No complaints with the backpack it is awesome. The hydration bladder is great as well. Would recommend the company and there product. ### ⭐⭐⭐⭐ Good *by A***S on September 7, 2016* I ordered this hydration pack in preparation for a three day music festival. The product came in a timely manner, however when my boyfriend went to use it, the bladder started to leak water. We couldn't see the hole but it ended up being useless.---After leaving the above review, the seller contacted me and said that they are willing to send a new bladder because of the faulty bladder.Besides the faulty bladder, overall a good hydration pack. I would recommend. There is a clasp to hold the hose down and there is a mouth guard and nozzle cover. Overall good quality. ### ⭐⭐⭐ the backpack fits comfortably; i have a 48 chest so the straps ... *by K***N on October 8, 2016* i don't understand why some manufacturers don't include instructions with the package. do i need to rinse/wash the pouch before first use? the backpack fits comfortably; i have a 48 chest so the straps make their way around just enough. gotta seal the hose really tight otherwise you'll have leackage in the bag and not realize it until later on. plenty of space for phone, wallet, keys, etc. draw on the hose is decent.before i ever took it out on the run (and I haven't yet), i put 1.75L of water in the pouch and walked around the house with the backpack on for a few minutes....realized that i hadn't tightened the hose enough.....the back of my shirt ** and whatever I would have put in the bag ** would have been soaked. I have never used these before....and i can't figure out what the hell that stupid little hole is in the top (blue) part of the bag. of course, instructions would be awesome!!!looks like a decent product but i would have given 4 (maybe 5) if instructions were included on best ways to use the product. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/31973869-sports-hydration-backpack-water-reservoir-bladder-2-liters-70-ounce](https://www.desertcart.us/products/31973869-sports-hydration-backpack-water-reservoir-bladder-2-liters-70-ounce) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-17*
