The Mayfly pitches rapidly and has many helpful particulars that enhance livability and make it straightforward to make use of whereas being priced considerably lower than NEMO’s different premium tent fashions.

Semi-Freestanding Design
The principle advantages of a semi-freestanding tent over a freestanding tent are weight financial savings from the diminished pole set and smaller packing measurement (see our FAQS on semi-freestanding tents and freestanding tents). The principle cons of semi-freestanding tents are that one finish depends on being staked out to carry the form of the inside, so you’ll be able to’t decide it as much as transfer it round, and it’s not as straightforward to pitch on a tent platform.
Material and Stakes
NEMO makes use of its proprietary OSMO cloth on the Mayfly, a mixture of polyester and nylon with the advantages of every (sturdiness for nylon, sag resistance for polyester). In my testing, I used to be impressed by how taut the OSMO cloth stayed in a single day and in moist situations, notably totally different from my expertise with nylon tents and tarps.
NEMO not publishes cloth denier info besides to notice the robustness of their heavier-weight flooring (68 denier), so we will’t communicate to the specs of the OSMO fly, the strong cloth on the underside half of the doorways, or the mesh. As is typical for NEMO tents, white mesh is used on the perimeters and black mesh on the roof to offer higher visibility for stargazing.
On the opposite tents I’ve used from NEMO, the flooring had been PeU-coated (polyether urethane), which doesn’t hydrolyze (break down and develop into sticky and smelly, particularly in storage) as PU (polyurethane) coatings can. Nonetheless, on the Mayfly, NEMO has gone to a PU ground. Whereas PU is cheaper than PeU, for those who’ve ever had a PU ground breakdown, you perceive why it’s known as PU. It is a step backward to decrease high quality, in my view. Right here’s an in-depth comparability of the 2 coatings.
NEMO’s different tents additionally include good stakes–powerful aluminum Y-shaped stakes with an upside-down J-shaped cutout to carry the rules securely. Nonetheless, the Mayfly comes with aluminum shepherd’s hook stakes–the sort that comes with a car-camping tent from a big-box retailer. So, a few funds selections have been made with the Mayfly, however at $400, this isn’t a funds tent.
Tent Setup
The Mayfly has a easy setup that may be accomplished rapidly with little observe. Unfold out the interior tent. Join the primary pole segments collectively into an enormous Y form, and insert the 2 arms of the Y into the Jake’s toes on the interior tent. Arc the pole excessive and clip the tail of the Y into the grommet on the foot finish. Clip the entire clips of the interior tent to the primary pole. Connect the crossbar excessive of the opposite pole, and clip the color-matched clip to it. Stake out the top and foot finish, pulling the fastened guylines to make the foot finish taut, with the pole struts at both nook standing up straight. Subsequent comes the fly.
On the head finish, the fly attaches to steel Jake’s toes with some distinctive {hardware}. The fly has a tensioner piece that appears like a key on a chunk of grosgrain ribbon, and the Jake’s foot has a keyhole. Put the important thing within the gap and switch it 90 levels to lock it in place.
I rapidly realized that if I attempted to attach the top finish of the fly first, the dearth of rigidity within the fly meant that the keys saved twisting and coming out of the keyholes as I moved from one facet of the tent to the opposite. However for those who join the foot finish of the fly first, slipping the guylines over the identical stakes holding up the foot finish of the interior tent, then connecting the loops on the apex of the fly to the crossbar, after which lastly attaching the head-end {hardware}, the fly is below sufficient rigidity that the keys maintain tightly of their keyholes. After all, that is all simpler in case you have two folks to arrange the tent and never only one.
Air flow
Air flow is that this tent’s sturdy swimsuit. One night time, I used it. It was 40*F with wind gusts of as much as 20 mph, and I may really feel the breeze on my face whereas mendacity down. The vestibules don’t come right down to the bottom; they’re catenary minimize to assist keep tautness and recent air consumption. Whereas there are strong cloth strips alongside the tent’s size above the bath ground (earlier than the mesh begins), these serve extra as privateness panels than as windblocks.
There’s additionally a scooped cutout of the fly on the head finish, NEMO’s signature, however this one is extra refined. You possibly can man it out to extend the house between the interior and the fly to get much more air alternate into the tent. The vestibules have two-way zippers and kickstand vents so you’ll be able to unzip them from the highest and prop them open for moist air to flee whereas nonetheless getting climate safety from the remainder of the vestibule being zipped up.
The air flow options make the Mayfly carry out very nicely on hotter nights and assist forestall condensation on wet ones. However exactly as a result of the airflow is so good, it’s not a tent I might take deep into the shoulder seasons. Additionally, one night time, I set it up within the rain, and in a single day, the temps dropped beneath freezing. Each vestibule zippers froze shut although there was a large storm flap protecting the zippers.
Tent Storage
The Mayfly’s primary stuff sack is rectangular formed for packability and has a rolltop closure. The identify “Divvy Sack” for these things sack has caught from the earlier design, primarily based on the concept that you could both pack the tent and poles collectively into an 18-inch lengthy package deal or break up the load between two hikers, with one taking the poles and the opposite one taking the tent and fly. With the poles eliminated, you’ll be able to compress the tent sack to about 13 inches lengthy by rolling the roll prime.
NEMO has accomplished away with the usual drawstring and cordlock closure on the stake and pole baggage in favor of an envelope development that works like non-zip sandwich baggage–you fold excessive to lock within the contents. It’s lighter weight and has nothing to interrupt, however it’s a little trickier to make use of with chilly arms or when carrying gloves.
Two Particular person Options
The Mayfly 2P is a snug tent for one particular person and a comfy match for 2 folks, with further room on the head and foot ends for a few of their gear and another storage options I element beneath. Every particular person has a C-shaped door, that means nobody has to climb over the opposite particular person to exit the tent and their vestibule, the place they will retailer their backpack, footwear, and water. As a result of the ground tapers right down to 42”, if you’re sharing the tent, neither of you need to use 25” extensive pads, which have gotten an increasing number of standard.
Notable Comfort Options
NEMO is excellent at together with little particulars and options that make their tents straightforward to arrange, enjoyable to make use of, and really livable. Listed here are a few of these design components on the Mayfly:
- Gatekeepers: A fast-stow function for rolling up the vestibule’s head finish and the interior tent doorways on either side. Slightly plastic two-pronged hook captures a twine lock on a grosgrain ribbon. It’s the quickest, best system I’ve ever used to maintain a tent door open, and you’ll function it with gloves on.
- Yellow light-diffusing headlamp pockets: Discovered at both facet of the tent’s head (one for every particular person). They solid a heat yellow glow that lights up the tent and that you could learn by whereas mendacity down.
- Gear loft: A triangle of tensioned mesh cloth on the tent’s peak is an efficient place to retailer bulkier (however nonetheless light-weight) gear off the ground and hold it simply accessible. I realized that whenever you put a down jacket up there, it could be damp with condensation from the nice and cozy, moist air that rises to the highest of the tent at night time.
- Gear loops: There are 7 small grosgrain loops, together with one on the heart peak that opens with a snap, across the ceiling for hanging glasses, small objects from a mini carabiner, or a clothesline.
- Cellphone/ Glasses pocket: A small, horizontal mesh pocket close to the height on the head finish between the headlamp pockets retains fragile objects from getting crushed or bumped.
- Coloured crossbar: It is a small pole, nevertheless it’s coloured vibrant orange to make it arduous to lose throughout setup.
