The Black Diamond Mega Light is a workingman's ultralight tarp shelter. As guides, some of us have logged hundreds of nights in one of these simple tents, waiting out storms and keeping loads gear dry for the next day. We appreciate them for their livability, adaptability, and value. Oh, and the Mega Light is enormous! We can spend weeks in this tent because of all the space for gear and cooking, and it fits four with room to spare. On spring ski tours, this tent becomes the roof a snow palace you can stand up in while you stay out of the wind or hide from the retina-frying sun. The Mega Light has its flaws, and it's one of the heaviest tents in the ultralight category. It doesn't score as high as the Hyperlight Mountain Gear Ultamid 2, which has a similar one pole design, but the Mega Light costs less than half of price, making it an affordable option.

Our Analysis and Test Results
The Mega Light can't match the weather-resistance and weight savings its competitors constructed from Dyneema composite fibers. Dyneema is lighter and waterproof, and it doesn't stretch when wet, while SilNylon tends to stretch when it gets wet. Like its cousin the Best Buy Award-winning Black Diamond Beta Light, the Mega Light can set up high for increased airflow, or guyed tightly to the ground to block rain and wind, or for a little extra privacy.
With some strategy and rigging practice, the Mega Light is an effectively weather-resistant tent. Without a floor, you'll need a lightweight nylon tarp or a piece of Tyvek to keep your stuff off the wet ground. After spending many rainy nights under this tent in the forests of western North Carolina, our testers have a few techniques for staying dry without the optional floor. The key is selecting a site that's not in a depression, ideally at a slight angle, and then dig a shallow moat on the uphill side of the tent, causing water to flow around the tent.
Equally crucial in pre-rigging some adjustable guy lines to the tie off points located on the exterior of the tent wall; then you'll be able to tighten them if the silnylon starts to stretch. The seams need to be seam sealed, and Black Diamond does offer a pre-sealed option. A tube of seam seal will set you back around $7 and an afternoon. We know this may sound like a lot of work, but we feel like the cash saved makes up for it. The Hyperlight Mountain Gear UltaMid 2 doesn't need seam sealing, and it won't stretch when it gets wet, but it also costs $715.
Fifty square feet of living space is pretty posh for an ultralight tent; one or two can inhabit this area with plenty of room to spare for gear and cooking space. No tent manufacturer recommends cooking inside a flammable, meltable tent, but in bad weather, it can happen. Without a floor and a high center, we feel decent preparing meals inside this design, especially in windy conditions. There aren't many bells and whistles attached to this pyramid, but there are a few features that score it some liveability points. At the apex of the tent is a large hole for ventilation (keeps the condensation down from all that cooking) with a hood to keep the rain out. This tent doesn't have any pockets, but there are a few tie-in points on the interior at the top of the tent. We like to string p-cord through the tie-ins for a place to hang socks, jackets, or anything else we need to dry. The Mega Light has one huge door that can be rolled back and secured open for plenty of ventilation.
The Mega Light packs down tiny in its included stuff sack, but combined with its single pole and stakes, it weighs 2.81 pounds, or 44 ounces, making it a heavy tent for the ultralight category. If you carry trekking poles, you can use them together with the included pole connector and save money without carrying the pole. For ski touring, we like to bring the pole, as the Mega Light makes a great base camp tent that we like to leave up for days. The Hyperlight Mountian Gear Ultamid weighs about eight ounces less. If you're using this one shelter for four people, the weight savings add up.
There isn't much in the way of bug protection unless you purchase the additional floor and bug net, doubling the price of this beast. If you set the Mega Mid up low to the ground, and keep the door closed, it's way better than sleeping out in the open, as our testers found while camping the buggy woods of western North Carolina.
This ten can only set up if it's staked down or tied to some type of rock or snow anchors. Aside from not being freestanding, the Mega Light is one of the most adaptable tents we reviewed. Like the Black Diamond Beta Light, the Mega Light is great for snow camping, and you can dig out the snow underneath to construct a bench for sleeping. The Pyramid design sheds snow, but be sure you've guyed out the sided with adjustable lines in heavy snow.
Ease of Set-up
Stake out the four corners, crawl inside, set up the center pole, head back outside to adjust the corners, and you're done. That's the scenario when you have a good surface in which to drive the stakes. On bare granite, you can still set up the Mega Light prided you bring some extra cord to tie around rocks or stuff sacks filled with rocks. The corners have short, fixed loops for staking, but they aren't big enough for attaching to large rocks or logs, so we recommend carrying some supplemental cordage to expand your set-up options.
This big guy is great for backcountry base camps, offering ample room for gear and cooking. 2.8 lbs isn't super light for a one person tent, but it is if you've got four of your friends sharing it. We've carried this tent miles into the backcountry along with large packs full of climbing and photo gear, and are very happy with its small packed size, weight, and versatility.
This tent retails for $299.95, a great deal for a huge and a lightweight shelter. Again, if you need better performance and at an even lighter weight, check out the Hyperlight Mountain Gear Ultamid, but if you plan on spending some serious time in the backcountry and don't want to blow your whole paycheck, the Mega Light is the pyramid style tent to get. If you don't need as much room, check out the even-more-affordable Black Diamond Beta Light.
The Mega Light is the affordable ultralight tent that several of our testers have used professionally for years. The simple design is very adaptable, and with some extra cordage and a little practice, you can set it up almost anywhere.
