Will this fit a 6’7” 270lbs man?

My husband is a large man and it worked for him. He is 6'5" and 340 pounds. He said he had plenty of room in the sleeping bag.

Who is the seller? Also, does this unzip at the foot area for ventilation?

I'm the seller,Yes,you can unzip at the foot area for ventilation。

How do determine left or right zip? While your in it or looking at it from outside the bag?

I'm sorry that I didn't explain left or right zip clearly. Left Zip：When you lie in sleeping bag to rest, the zipper is beside your left arm; Right Zip：When you lie in sleeping bag to rest, the zipper is beside your right arm; And you can see the letter L or R at the bottom of the storage bag. L represents the Left Zip,and R represents the Right Zip.

How do I fully open this to be a mat. I got one with one zipper at the bottom but there are two zippers at the side going in opposite directions.

you can open this sleeping bag to be a mat,simply unzip the both bottom and side zip. How to open the side zipper? it is a two-way zipper, just move the two zipper heads together to the bottom of the zipper,must be the bottom and align two zipper heads,then you can unzip it.I hope my answer can help you. It is worth mentioning that side zipper can be pulled in two way directions to facilitate ventilation.
