Rather than rating our hammocks for overall breaking strength, we go by a Comfort Rating.
Comfort Rating is a maximum weight weight that will still allow you to lay reasonably flat without too much excess stretch. For a firm and flat lay, you should try to stay well below the Comfort Rating of the hammock. This will provide you with the most comfortable nights sleep.
Below is a link to our Comfort Rating Calculator.
Please keep in mind the 1.0oz MONOLITE and 1.2oz MTN XL are ultralight fabrics. Even though they offer good strength for their weight, these fabrics will not offer the same durability and long lasting service that the heavier fabrics will provide. Even if you fit within the comfort rating of a particular fabric, it may not be the right fabric for you. If in doubt, go heavier on the fabric and enjoy the added comfort and durability. We stand behind our workmanship 100%, but because of the limited durability of ultralight fabrics in general, we cannot provide any sort of warranty coverage for failure of these lighter weight fabrics. Please use these ultralight fabrics at your own risk.
