S'well Stainless Steel Water Bottle 17oz Moonstone - Long-Lasting

In this review of the S'well Stainless Steel Water Bottle 17oz in Moonstone, the bottom line is simple: this bottle is for anyone who wants reliable temperature retention in a stylish, everyday carry. The biggest reason to buy is its triple-layered insulation, which keeps cold drinks cold for extended periods and hot drinks warm for hours, making it a practical companion for long commutes, gym sessions, and day trips. The design balances form and function, fitting most cup holders and keeping hands and bags dry thanks to its no-sweat exterior.

Key Features

• Triple-layered insulation: Therma-Swell Technology sustains cold for up to 36 hours and hot for up to 18, so beverages stay at serving temperature throughout the day.
• Premium stainless steel build: Made from 18/8 food-grade stainless steel for safe, reusable hydration without BPA or BPS.
• Wide opening: The mouth is large enough for most ice cubes, making refills and cleaning easier while still keeping a sleek silhouette.
• Condensation-free exterior: The bottle does not sweat, protecting bags and keeping the grip comfortable in handheld use.
• Designed for portability: The 17oz size fits most standard cup holders and backpack side pockets for everyday convenience.
• Hand-wash care: The bottle is crafted for durability and beauty but requires hand-washing to preserve the finish.

Who It's For

The S'well 17oz Moonstone is ideal for commuters, students, and gym-goers who want a dependable insulated bottle with a refined appearance; its long thermal retention and cup-holder-friendly size suit all-day outings. It also works well for anyone replacing single-use plastic with a reusable, BPA-free container.

Shoppers who need a dishwasher-safe bottle or require heavy-duty impact resistance should look elsewhere; some users report dents and finish wear over time. Those who prioritize ultra-lightweight materials for long backpacking treks may prefer a different style tuned specifically for weight savings.
