Very compact when empty so easy to carry on hikes upthe mountains before flying down with the empty bottle in my pocket. However still a steep price. ### ⭐⭐⭐⭐⭐ Review *by B***R on 1 July 2025* These are a life saver while out hiking. The pack light when not in use and also do a good job of keeping your drinks a little cooler than some other products I've used in the past. Quality made and very durable, no leaks at all after months of use. ## Frequently Bought Together - Hydrapak UltraFlask Speed 600ml - Collapsible Soft Flask Water Bottle for Hydration Vests and Running Packs with Easy Open Cap (600 ml/20 oz), Malibu Blue - HydraPak 42mm Filter Cap - Water Filtration Accessory - Fast Flow - Perfect for Hiking, Endurance Sports, Camping, Travel, and Emergency Preparedness --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/436758364-hydrapak-ultraflask-speed-500ml-or-600ml-collapsible-soft-flask-water](https://www.desertcart.vn/products/436758364-hydrapak-ultraflask-speed-500ml-or-600ml-collapsible-soft-flask-water) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-18*
