Product Overview

I recently tried the Coolflask Galaxy Large Metal Stainless Steel Flask with Carrier and was impressed with its features and design. The flask is made of stainless steel with a unique matte finish, gradient powder coat, ice speckles and laser engraved logo for an eye catching look. It has a double wall vacuum structure that keeps cold beverages cold for up to 48 hours and hot drinks hot for 24 hours. I also appreciate the three lid pack which includes a easy twist spout lid, flip up straw lid, and wide mouth handle lid so you can drink from it in different ways.

The flask is made of 18/8 food grade stainless steel which makes it BPA free, rust and corrosion resistant, and free from odor retention. It also comes with a lifetime warranty against manufacturing defects for worry free use. Plus, it s easy to clean by hand washing only.

I found that this flask is great for outdoor activities such as hiking or camping trips where you need to stay hydrated throughout the day without having to refill. It s large capacity 4 pounds means that you don t have to refill it often and its vacuum insulation keeps your drinks at the desired temperature. It also comes with a carrier strap which makes it easy to carry around when you re on the go.

Overall, I think this flask is great for anyone who needs to stay hydrated while outdoors or on long trips. Its stainless steel construction makes it durable and reliable while its insulation ensures that your drinks remain at their desired temperature for hours on end. The three lids make it easy to drink from while its carrier strap allows you to easily carry it around wherever you go. If you re looking for an insulated flask that can keep your drinks cold or hot all day long, then I highly recommend the Coolflask Galaxy Large Metal Stainless Steel Flask with Carrier.
