Perfect for 2P Dog, tight squeeze for 3P

Picked up this item on sale, and I see that it currently still is as of April 2026. For the price and weight, the mayfly 3p serves 2 people and a medium sized dog quite well. Setup/takedown was easy, and packed easily into a Durston 40L with a BV450. Inside the tent you get more than enough storage pockets, and the light diffusers worked as needed. No real complaints on trail, performed well in wet conditions and was easy to rinse/dry afterward. However, the previous comment is accurate — sleeping 3 would require climbing over each other at some point. The tent is definitely a tight fit with no floor space if sleeping 3. Granted, my expectations were tempered since my goal was a comfy 2p with room for a dog, but I’m very happy with the product. Fit an ExPed duo 6.5R with ample floor space for gear.

not good for 3 people

Tent is nice and light for 3 people but the doors are on the sides so the person sleeping in the middle always has to wake someone up to go to the bathroom…poor design for 3 people…doors should be at the feet. We will be returning this tent.
