The UltraSpire SoftFlask 500ml is the perfect companion for your hydration vest or waist pack, designed to shrink as you drink. This eliminates air from the bottle, keeping your water quiet and your center of gravity stable. Equipped with a high-flow, self-sealing bite valve, it delivers effortless hydration when you're redlined on a climb, then tucks away easily once empty. It’s a simple, soft, and durable solution for runners who want to carry their water without the bulk.\n\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eCollapsible Design:\u003c\/b\u003e The flexible TPU material shrinks as you hydrate, significantly reducing water movement and \"sloshing\" while allowing the flask to be stashed in a pocket when finished.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eHigh-Flow Bite Valve:\u003c\/b\u003e Features a soft, self-sealing silicone bite valve that provides a steady stream of water with minimal effort and stays leak-proof between sips.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eUniversal Vest Fit:\u003c\/b\u003e Specifically shaped to slide easily into the front pockets of most major hydration vests and specialized running packs.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eBPA \u0026amp; PVC Free:\u003c\/b\u003e Constructed from food-grade, taste-free TPU that is rugged enough for the trail but safe for daily use.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eWide-Mouth Opening:\u003c\/b\u003e Makes it easy to fill at the tap, add ice cubes for those humid afternoon runs, or stir in your favorite electrolyte powder.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eEasy to Clean:\u003c\/b\u003e The soft material is durable enough for the top rack of the dishwasher (remove the valve first) for quick and easy maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eBest For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eThe Effort:\u003c\/b\u003e Daily training runs, trail racing, and hiking with a hydration vest.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eThe Goal:\u003c\/b\u003e Silent, bounce-free hydration that doesn't take up space once it's gone.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eThe Conditions:\u003c\/b\u003e Every adventure—from humid coastal road loops to dusty backcountry singletrack.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eCapacity:\u003c\/b\u003e 500 ml \/ 17 fl oz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eWeight:\u003c\/b\u003e 34 g \/ 1.2 oz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eMaterial:\u003c\/b\u003e BPA, Phthalate, and PVC-free TPU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eValve Type:\u003c\/b\u003e High-flow silicone bite valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eCompatibility:\u003c\/b\u003e Fits most standard running vest front pockets\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UltrAspire","offers":[{"title":"Default Title","offer_id":45550247837753,"sku":"210000010089","price":32.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0773\/3251\/2825\/files\/fyzzrnzma2px9ulyu14t.png?v=1772223935","url":"https:\/\/3mile.ca\/products\/ultraspire-softflask-500ml-w-bite-valve","provider":"3 Mile Outfitters","version":"1.0","type":"link"}
