## Description

The SoftFlask Speed is specifically designed to be compatible with the widest range of vests and packs. Replacement or upgrade, the pinch-welded bottom makes loading into pockets a cinch. Its secure, single-handed SpeedFill™ flip top makes filling fast — both water and fuels — and the self-sealing silicone bite valve delivers sips, not drips. And all this weighs just grams. Included in the package: - SoftFlask 500ml Flask - SpeedFill Cap - Bite Valve - Basic Care & Use Instructions Specifications: - Capacity: 500 mL / 17 fl oz - Weight: 46 g / 1.6 oz - Dimensions: 260 mm x 80 mm / 10.2 in x 3.1 in - Material: TPU, PP, Silicone, POM, 304SS.

Review: Well thought out design and quality build - Only a month into using these, but they have been fantastic bottles. I do wonder how the flip cap seal will hold up over time, but so far they have been flawless. PROS: - easy to screw on/off cap even after being in the freezer (stored there to avoid mold) - flip cap is very useful on quick pit stops - fit in all of my hydration vests
Review: quality - This water bottle is a great size for what I need — I usually cycle for about 1–2 hours a day. The only problem is that the main cap got stuck and I couldn’t get it unstuck, but it has a small lid that still lets me fill it with water. I didn’t return it because it’s actually the best one I’ve had so far, and it doesn’t give the water any smell or taste, good quality, and easy to carrying. I like it.

## Features

- FITS HYDRATION VESTS AND PACKS: Soft material and an innovative pinch-welded base creates a low-profile tapered flask. Fits easily in most hydration vests, belts or pack pockets.
- COLLAPSIBLE FLASK: Soft material conforms to any pocket, and shrinks as you drink to reduce movement and pack away easily when empty.
- PERFECT FOR AID STATIONS: SoftFlasks are equipped with our SpeedFill Cap designed for quick and easy refilling at aid stations. A side tab pops open the cap in one motion and snaps shut with a click.
- FILTER COMPATIBLE: Compatible with 42mm threaded backcountry water filters including the HydraPak 42mm Filter Cap.
- BEYOND LIFETIME WARRANTY: If you experience any issue, we’ll repair or replace the item for free. Whatever it takes to keep your adventure going.
