Review: 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! Review: Like all My other hydroflask products- works well, as detailed, and certainly recommended . Note this is not a large capacity bottle- I use it in day pack but have a larger version in car . ## Features - 24 hours cold, 12 hours hot - TempShield️ double-wall vacuum insulation - Leakproof when closed - Pure taste, no flavor transfer - Durable stainless steel ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D3VKX2JP | | Additional Features | Vacuum Insulated | | Age Range Description | Adult | | Best Sellers Rank | #3,892 in Sporting Goods ( See Top 100 in Sporting Goods ) #226 in Sports Water Bottles | | Brand Name | Hydro Flask | | Cap Type | Flex Cap | | Capacity | 1 Fluid Ounces | | Color | Moonshadow Purple | | Customer Reviews | 4.7 4.7 out of 5 stars (237) | | Global Trade Identification Number | 00840394203737 | | Included Components | Bottle | | Is Oven Safe | No | | Is the item dishwasher safe? | No | | Is the item microwaveable? | No | | Item Dimensions W x H | 15W x 25H centimeters | | Item Type Name | Water Bottle | | Item Weight | 0.34 Kilograms | | Manufacturer | Hydro Flask | | Material Type | Stainless Steel | | Model Name | Standard Mouth Flex Cap Bottle | | Number of Items | 1 | | Pattern | Solid | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | Water | | Theme | Sport | | UPC | 840394203737 | | Unit Count | 1 Count | | With Lid | Yes | ## Product Details - **Brand:** Hydro Flask - **Capacity:** 1 Fluid Ounces - **Colour:** Moonshadow Purple - **Recommended uses for product:** Water - **Special features:** Vacuum Insulated ## Images ![Hydro Flask 21 Oz Standard Mouth Flex Cap Moonshadow - Image 1](https://m.media-amazon.com/images/I/61eFEyzPSHL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***S on 4 July 2023* I love Hydroflasks!

Note this is not a large capacity bottle- I use it in day pack but have a larger version in car . ### ⭐⭐⭐⭐⭐ Review *by N***A on 7 July 2024* Every time I buy another brand of water bottle, I am always disappointed. Hydroflask never disappoints - I like the wide mouth, easy to wash and sanitize design, and gorgeous colors that don't chip. I have had my Hydroflasks for years and the paint doesn't rub off with time. I just bought this cute new cactus color to tote around in my handbag and I'm drinking more water as a result. ## 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.fr/products/667394343-hydro-flask-21-oz-standard-mouth-flex-cap-moonshadow](https://www.desertcart.fr/products/667394343-hydro-flask-21-oz-standard-mouth-flex-cap-moonshadow) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-04-27*
