Review: Perfect! - I love Hydroflasks! I bought this to replace one that I had been using daily for years. The old one had taken a real beating! It had several dents, and the coating was starting to chip just a bit. I love my new one! Same great Hydroflask quality and vibrant color! I really like the top which is easy to loop a finger or two though for carrying! It also fits well into my car's cupholder and the cupholder of my day pack!

Same great Hydroflask quality and vibrant color! I really like the top which is easy to loop a finger or two though for carrying!

Have been a long-time Nalgene person, but wanted something thin that fit inside a Jean jacket inner pocket. Saw this color and hit purchase without even thinking, however I had a hard time choosing a size. Chose the smaller size because I wanted the shorter height. Bottle came and is definitely lighter than expected. Color is vibrant and DISHWASHER SAFE!! Wooooo! Can’t wait for my first flight to flex. ## Frequently Bought Together - Hydro Flask - Water Bottle 621 ml (21 oz) - Vacuum Insulated Stainless Steel Water Bottle with Straw Cap - BPA-Free - Standard Mouth - Moonshadow, Fossil - Hydro Flask - Flex Straw Cap for Standard Mouth - Leakproof - Honeycomb Insulated Cap with Flex Strap for Easy Carrying - BPA-Free and Toxin-Free - Dishwasher Safe - Black --- ## 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.tw/products/667394343-hydro-flask-21-oz-standard-mouth-flex-cap-moonshadow](https://www.desertcart.tw/products/667394343-hydro-flask-21-oz-standard-mouth-flex-cap-moonshadow) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-08-13*
