      Super comfortable but is very big packed

      I bought the 30x80 system, it is the best system I have ever used, the only issue is I motorcycle camp off of a adventure bike and the mattress takes up waaayyyy too much room in the saddle bags, I was concerned about this before I bought it and called the company for advice and a recommendation. They recommended the flex d and I definitely should of went with the light mattress.

      Short answer: get it. Purchased this mat to upgrade my current sleep system. Just used it car camping for a weekend trip. Its definitely not a backpacking mat, but for car camping, it’s amazing. Easy to inflate and easy to adjust. Very comfortable and packs down smaller than other pads of similar dimensions. Highly recommend. Zenbivy is now my go to for sleep system gear.

      Best sleep in a tent ever

      I bought this for my husband, but he didn't want to carry it backpacking because it is much heavier than his tiny pad. I decided to take it, and I had the best sleep ever in a tent. I found it to be very comfortable and for me it is worth carrying a little extra weight. Sleep is so important! I will sacrifice something else, but not this pad.

      Not bad

      Good quality and construction. But not as comfortable as I would hope for the money spent.
