## Overview

The FITLY Soft Flask is a 5 oz (150ml) collapsible, BPA-free hydration bottle designed for runners, hikers, cyclists, and outdoor athletes. Its lightweight, flexible TPU body shrinks as you drink to reduce sloshing and bulk, fitting seamlessly into running vests, belts, and hydration packs. Featuring an easy-sip bite valve, it enables quick hydration on the move during short to medium workouts. Freezable, leak-proof, and reusable, this flask is the perfect minimalist companion for active lifestyles.

## Description

The FITLY Soft Flask is built for active hydration when a hard bottle feels too bulky. This compact 5 oz / 150ml collapsible running water bottle gives runners, hikers, cyclists, skiers, and outdoor athletes a lightweight way to carry quick sips without adding extra weight to a vest, belt, pocket, or hydration pack. Its soft, flexible body shrinks as you drink, helping reduce sloshing, bouncing, and empty-bottle bulk during movement. The bite valve makes it easy to sip while running, riding, hiking, or moving through race-day intervals, while the compact size works well for short to medium sessions, quick hydration breaks, gels, or supplemental fluids alongside a larger bottle or hydration bladder. The packable design folds down small when empty, making it easy to store in running belts, hiking packs, bike bags, luggage, and event-day gear. BPA-free reusable materials make it a practical choice for regular workouts, travel, outdoor adventures, and active daily use. For best results, rinse before first use, clean after each outing, and let the flask air dry fully before storing. Choose FITLY when you need a soft water bottle that stays light, saves space, and fits naturally into your running, hiking, cycling, skiing, and outdoor hydration setup.

Review: Cok iyi - Maraton ve orta mesafe koşulları için çok güzel.
Review: Water is super important - I live in Fl, and I run outside. Those two components demand that I hydrate or die. I prefer the land of the living for now, so gimme the H2O. I already had the Fitly minimal pack, just not this particular flask. I originally thought I would have to bite the bullet and get a new pack altogether, but then I found the flask available by itself. I ordered, it arrived, and I have been using it for a couple weeks now. A decent amount of water for daily runs, depending on speed and sun exposure I would say 1-2 hrs. The only hiccup I have noticed is the screw on top with the hose attached can be a little tricky to get on without spilling some water. Other hydration packs have a slide that seals the reservoir; I can see why the screw top here, based on minimalist approach. It is worth the small effort with closing to be able to have a smaller pack to carry.

## Features

- SOFT FLASK FOR RUNNING: Compact 5 oz / 150ml soft flask gives runners quick hydration for short runs, race day fueling, gym sessions, hiking, cycling, skiing, and outdoor workouts without carrying a rigid bottle.

- RUNNING VEST COMPATIBLE: Slim soft water bottle is made for active gear setups and fits many hydration vests, belts, and pack pockets, giving runners and hikers a lightweight way to sip while moving.
- BITE VALVE HYDRATION: Easy-sip bite valve helps you drink on the go during runs, rides, hikes, and races, so you can hydrate between intervals, trail sections, or workouts without stopping to unscrew a bottle.
- BPA FREE AND REUSABLE: Made for repeated active use with BPA-free materials, this reusable hydration flask is a practical choice for runners, cyclists, hikers, travelers, and outdoor gear bags.
- LIGHTWEIGHT PACKABLE DESIGN: Folding water bottle packs down small when empty, saving space in running belts, hiking packs, bike bags, luggage, and race-day kits while staying easy to carry and store.
- IDEAL 150ML COMPACT SIZE: Small 5 oz capacity is best for short to medium sessions, quick sips, gels, or supplemental hydration, helping avoid extra weight when you do not need a larger 250ml or 500ml flask.

### ⭐⭐⭐⭐⭐ Ideal for running!
*by T***X on 19 March 2023*

I love using soft water bottles because they don't take up much space. They are lightweight, flexible and collapsable which is ideal for when I go running! And this one fits perfectly into my waist bag :) It's also leakproof and I did not notice any bad taste in my water plus I really like this type of mouthpiece!
