{"product_id":"ultraspire-softflask-800ml-w-locking-cap","title":"UltraSpire SoftFlask 800ml with Locking Cap - High-Capacity Running Flask","description":"\u003cp\u003e\n  Sometimes 500ml isn't quite enough to get you through that remote stretch of the Bluff Trail or a humid July afternoon in the highlands. The UltraSpire SoftFlask 800ml is the \"long-haul\" answer to portable hydration. It provides that extra volume you need for self-supported efforts without the bulk or \"slosh\" of a traditional rigid bottle. This version features a secure, thumb-activated locking cap rather than a bite valve, making it the perfect choice for stashing in a pack side pocket or a large waist belt where you need 100% leak-proof security. As you drink, the flask collapses, keeping your water quiet and your gear dry, no matter how technical the terrain gets.\n\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eExtended 800ml Capacity:\u003c\/b\u003e Offers significantly more volume than standard 500ml flasks, perfect for longer gaps between water sources or high-sweat training days.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eLeak-Proof Locking Cap:\u003c\/b\u003e A secure, twist-to-lock or thumb-lock design that ensures your water stays in the bottle even when it's being squeezed inside a tight pack pocket.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eCollapsible Design:\u003c\/b\u003e The soft, flexible TPU material shrinks as you hydrate, eliminating air and preventing the annoying \"water-slap\" sound common with hard bottles.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eTapered Fit:\u003c\/b\u003e While larger in volume, the flask maintains a streamlined shape designed to fit comfortably in larger vest pockets, waist packs, or the side sleeves of your favorite daypack.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eSafe \u0026amp; Durable Construction:\u003c\/b\u003e Made from abrasion-resistant, food-grade TPU that is BPA, PVC, and Phthalate-free, ensuring your water tastes like water, not plastic.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eHigh-Flow Performance:\u003c\/b\u003e The wide cap allows for rapid drinking and fast refills, so you can spend more time moving and less time standing at the tap.\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 Self-supported long runs, fast-packing, and high-intensity hiking.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eThe Goal:\u003c\/b\u003e Carrying more water with less bounce and absolute leak-proof security in your gear.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eThe Conditions:\u003c\/b\u003e Hot Maritime summers, remote trails, and adventures where refill points are few and far between.\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 800 ml \/ 27 fl oz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eWeight:\u003c\/b\u003e Approx. 45 g \/ 1.6 oz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eCap Type:\u003c\/b\u003e High-flow locking cap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eMaterial:\u003c\/b\u003e 100% BPA \u0026amp; PVC Free TPU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eDimensions:\u003c\/b\u003e Designed to fit standard larger hydration pockets\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UltrAspire","offers":[{"title":"Default Title","offer_id":45550246854713,"sku":"210000011159","price":37.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0773\/3251\/2825\/files\/ylrwpulppbcbzmaagtdh.png?v=1772223926","url":"https:\/\/3mile.ca\/products\/ultraspire-softflask-800ml-w-locking-cap","provider":"3 Mile Outfitters","version":"1.0","type":"link"}
