Keeps drinks warm for a 3 hours or cold all day. No valve in the straw which we prefer as easier to drink and clean. So strudy, used daily for a year and still fine. But this bottle!! ### ⭐⭐⭐⭐⭐ Excellent flasks for the girls school water bottles *by on Reviewed in the United Kingdom 31 August 2016* Excellent flasks for the girls school water bottles. Keep drinks nice and cold in the hot weather. Also does not leak. I think I'll have to order a new top in the future though as my daughter bites the straw. Think it's good that you can order the tops seperately. ### ⭐⭐⭐⭐⭐ Worth the money *by on Reviewed in the United Kingdom 28 March 2026* It’s hard nowadays to get a good water bottle for the kids. It’s a good size, not too small, not too big. Keeps the water inside hot or cold! Really worth it! ## Frequently Bought Together - Thermos - Blue Water Bottle (355ml) - BPA Free, Stainless Steel, Spill Proof, Pop-Up Straw, Kids Flask with Personalised Name Labels & Carry Handle for 12-Hour Cold Drinks - Football FUNtainer Bottle 335ml - Thermos Replacement Straws for 12 Ounce Funtainer Bottle, Clear, one Size (F401RS6) --- ## 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/47892842-thermos-blue-kids-boys-drinks-flask-355ml-12hrs-cold-stainless](https://www.desertcart.us/products/47892842-thermos-blue-kids-boys-drinks-flask-355ml-12hrs-cold-stainless) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-14*
