I contacted Baen Sendi because I thought there was supposed to be an O-ring on the screw cap to prevent leaks. After rereading reviews on Amazon and getting a response from Baen Sendi I found out there is no O-ring. I apparently just received a defective product. After getting a refund and ordering a replacement I found that the new bladder also leaked from the screw cap - when I first filled it. I then tightened the screw cap and it held with no leaks. I believe I tried tightening the first one I received and I couldn't get it to stop leaking. So bottom line, I like the product for it's two openings (fold top and screw cap). The plastic seems to be much heavier than the bladder this is replacing. The tube has a valve cover and neoprene insulating wrap. Users need to know that the screw cap needs to be on very tightly. This does make it leak free but it also makes it somewhat difficult to unscrew. Perhaps this will work easier with use. ### ⭐ wish it would have worked out. *by T***N on Reviewed in the United States on June 28, 2019* I'm sad. I purchased this after reading all the positive reviews. I'm going camping tomorrow so I paid to have it expedited. Tonight I was filling it with water and prepping all my gear and discovered what looks like staple holes in it. I'm not going to bother returning it because I like the cleaning kit that came with it and plan on keeping those. I ended up just going to an outdoor store here in town and paying $50 for the same size bladder. I wish quality control had done a better job as I'm sure this would have worked great. ### ⭐⭐ Hose Came Loose *by _***_ on Reviewed in the United States on July 27, 2020* This bladder survived maybe 6 long hikes before finally failing. I never had issue with the bladder or cap. The problem was the point where the hose connects. It wedges in and twists/locks into place with little triangular teeth. The problem is they're plastic, and over time the teeth wear down causing the hose to slip. I recently replaced it with a different system that uses a spring-loaded button hose connector, and it works much better. --- ## 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.pl/products/87503421-hydration-bladder-3-liter-100-oz-2-liter-70-oz](https://www.desertcart.pl/products/87503421-hydration-bladder-3-liter-100-oz-2-liter-70-oz) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
