The Sierra Designs Flash 3 FL tent is an ultra-lightweight, roomy, freestanding, external pitch tent that provides ventilated refuge in a matter of seconds. Two doors and two gear closets supply easy access and storage, while steep walls give an open feel when you’re inside.

The Flash 3 FL offers 41.2 square feet of usable interior space, making it comfortable for two people and luxuriously spacious for solo campers. Dual gear closets are accessed from inside the tent to keep gear storage out of the way of the doors and provide an additional combined 14 square feet (7 sq. ft. per closet) of sheltered space for for stashing larger items like packs and boots.

When wet weather threatens, the quick, external pitch set-up provides a dry, well-ventilated space in a matter of seconds, while the reflective door trim and guy outs make finding your tent in the dark an easy task.

The hybrid double/single wall design of the Flash 3 FL adds stability without weight, while ultra-light clips, DAC NFL aluminum poles, 15" integrated awning poles that maximize the door openings and drip lines without the weight of a support pole and uncommonly large single drop doors add to the list of great features. The trail weight of the tent is 4 pounds, 2 ounces.

Ample mesh on the tent body and the dual doors maximize cross ventilation and provide circulation to fight condensation build-up in the Flash 3 FL. Coated with waterproof polyurethane, the 30D nylon ripstop floor and 20D polyester ripstop rainfly are lightweight and durable. The rainfly also has venting to create internal airflow. All of the Flash 3 FL’s seams are tape-sealed to protect the tent interior from the elements.

A custom-fit footprint (sold separately) can be used to further protect the floor of the Sierra Designs Flash 3 FL against rocks, exposed roots, mud and ground water.

  • Freestanding design can be pitched anywhere
  • Large double drop doors wide enough for 2 to sit
  • 15” integrated awning poles maximize door opening
  • Hybrid double/single wall reduces weight and provides quick, dry setup

New style of tent for me. Not perfect.

Likes: I have slept ten nights in this tent in CO and AR, conditions ranged from warm and sunny to low 20's and windy. The tent has seen rain, sleet and wind and came out of all these scenarios keeping us dry and out of the elements.

I really liked the large doors. Setting up the tent couldn't be any simpler because all the poles are joined together. The headroom is good and the walls don't have a very severe slant towards the peak. I have never slept with three people in this tent, two adults and medium sized dog was pretty comfortable though.

Dislikes: The big selling point for this tent is the wide open door with a view. To get that you give up the big vestibule. I would rather have the big vestibule. The gear closets are annoying to get gear in and out of. We mainly used them to store wet shoes and dog gear. The hybrid single wall/double wall is nice, but if you end up with lots of condensation inside the fly (or frozen condensation between the fly and the mesh ceiling), it's really hard to get back on the trail without packing a wet tent.

All in all this is a nice tent, but I will be going back to a tent with vestibules.
