My thoughts and review

The Stanley Master Flask: A bold flask for bold adventures

What you see here is exactly what you get. Rather than being just another stylish flask like many others, the Master Flask is Stanley’s heavy-duty makeover to entertain those with hardwearing lifestyles. This is a thicker flask that can take a beating and get tossed around without any concern for leaks or damages. With that being said, its toughness comes at a price. The Master Flask is a going to be a little heavier and bulkier than other flasks on the market. This is by no means a deal breaker as it doesn’t make a significant difference, but it is going to be a little unsubtle to be carrying around on your person, especially while wearing lighter clothing.

Aside from its stout build, Stanley implemented a few features that add a nice tough. The Master Flask has a wider mouth opening compared to other flasks which makes it a little more convenient to pour or drink. The Foundry black powder coating not only gives the flask a nice look but it also adds a nice textured grip. The Stanley Master Flask currently has an MSRP of $35. Not a bad price for a burly flask that can handle your rough excursions and take some serious abuse.
