Soft Flask - 13.5 oz (400 ml) Hydration Pack/Running Vest Water Bottle

FITLY's SOFT FLASKS are a range of premium running accessories, first launched on Kickstarter, that are small, collapsible, and part of the brand's product line. These flasks are designed to be the ideal hydration solution for quick drinks on the move.

The FITLY Soft Flasks are versatile and can be used to quickly gobble up a gel, wet a dry throat, or re-hydrate during activities. Designed specifically for use while running, these flasks can be stored directly in the front, side, or back pockets, as they shrink as you drink, ensuring they never move, bounce, or rattle.

The product line offers five models to choose from: FLASK150 (5oz), FLASK250 (8.5oz), FLASK350 (12oz), FLASK400 (13.5oz), and FLASK500 (17oz). The FLASK500 comes with FITLY Sub90 and is too large for the FITLY Sub45.

It's important to note that the Soft Flasks are not designed for use with viscous substances like gels, but rather for flowing liquids. Many runners use a mixture of water and gel, as the thinner consistency travels better through the mouthpiece.

The flasks are all hand-sealed, and users can expect minor volume variations of up to 1 oz (up or down). To get the most out of the FLASK500, users can keep it cool by leaving it in the fridge or freezer, and even mix in a gel with water to add some extra energy or squeeze in a lemon for flavor.

The flasks are top-rack dishwasher-compatible and should be thoroughly washed before first use. If users experience any taste, they can rinse with baking soda until it disappears.

The key features of the FITLY Soft Flasks include: - Soft bite to quick flow - Leak-resistant and rigid cap ring for easy refill - Durable, built to last - No detectable plastic odor or taste - Compatible with FITLY's Innovative Running Packs, hydration vests, running belts, and backpacks

The flasks' durable and leak-resistant mouthpiece requires a gentle bite to allow the liquid to flow out. Users should twist the mouthpiece shut to prevent leaks and can apply natural oil to the threads to increase the seal if needed.

The variety of flask sizes cater to a wide range of activities, from 5oz to 17oz, and are surprisingly easy to use. The flasks have been thoroughly tested and re-tested, with the mouthpiece designed to have a hard and soft part, allowing the user to gently bite the soft part to enable a gushing flow of liquid.

The FLASK500 model comes with a 17oz soft flask, two mouthpieces (one for standalone use and one with a 45-degree rotating mouthpiece and a 23-inch tubing system).

Overall, the FITLY Soft Flasks have received positive reviews from customers, with many praising their functionality, durability, and ease of use during various activities.
