Our Verdict

The Mountain Laurel Designs Grace Tarp Duo in Pro SilNylon, is the best value ultralight shelter that we've tested. It is larger than most two-person, A-frame style tarps, and the pronounced catenary-cut ridge makes a taught A-frame pitch easy to achieve. When pitched close to the ground, the coverage provided is enough for two folks to stay nice and dry in all but the windiest rainstorms. While its design limits the way it can be set up to simple A-frame mode, we loved that Mountain Laurel Designs gives you the option of upgrading, or adding on to, nearly every aspect of this tarp. If you are looking to enter the ultralight realm without breaking the bank, we highly recommend this exceptionally well-built tarp. Weighing in at only 15.1 ounces, it's very light on the scale as well. We've previously tested the much lighter DCF fabric version of this tarp, which we also highly recommend if you have the extra cash.

We have tested the Mountain Laurel Designs Grace Tarp Duo many times, and no matter who uses it or in what conditions, it is still a tarp that we come back to with fondness. As a catenary cut tarp, it can really only be set up in one way, A-frame mode, which is one of the simplest and most common ways of pitching a tarp anyway. This leaves two ends open, although it is common to have the feet end of the tarp significantly closer to the ground, offering more shelter than the head end. Regardless, these limitations caused it to rank lower than most in this review for weather protection and adaptability, two important metrics for assessing performance of an ultralight shelter, and thus its cumulative score was in the lower third of the review.

That said, we still love this shelter and think it presents excellent value! We also love that virtually everything about it is either upgradable, or can be added on for a slight upcharge. For instance, you can choose to buy this tarp made of Pro SilNylon, as we did, or three different thicknesses of DCF fabric (+$130, 7.5oz. total! Or 10oz. or 11oz. ). Likewise you can pay to have them seam seal the SilNylon version for you ($30), add two carbon fiber poles so you don't need to use trekking poles (+$50, 2.6oz.), add titanium skewer stakes (+$25, 2.6oz., not the quality or durability we would want to use), or upgrade to reflective guy line (+$6). This tarp also comes in both Duo size, which is what we tested, or solo size.

Like many of the products in this review, the Grace Tarp Duo is not available from major retailers - only directly from the small manufacturer in Virginia. We only had to wait more than a few weeks for the SilNylon version that we tested, which MLD reports is typical for SilNylon. However, if you're looking for DCF, you'll probably have to wait a few weeks longer.

Performance Comparison


The MLD Grace Tarp Duo scored in the bottom half of our overall comparative rankings, as you can see below highlighted in blue. This was due mostly to lower scores for weather protection and livability, drawbacks of using a tarp as your primary shelter.


If you're seeking an ultralight shelter for backpacking that won't break the bank  this top quality SilNylon A-frame cost about a third of what the most expensive models do.

Weather Resistance


The Mountain Laurel Designs Grace Tarp Duo provides good enough weather protection in most backpacking environments. The two open ends can be a drawback though if you select an exposed campsite and it turns rainy and windy. We find that almost all established campsites are in well to moderately well-protected areas where an A-frame works great. Eight perimeter Line-Locks allow you to securely stake out and tension this A-frame. There are no field guy outs on this tarp; it would be nice to have mid field guy outs on the sides. SilNylon stretches when wet, but having the adjustability of the Line-Locks within reach from inside allows you to tighten things up without going out in the rain.

The catenary cut of the Grace Tarp means that it really only works in A-frame mode  leaving two openings for wind and rain to enter. This setup has the rear pole adjusted shorter than the front  and the left side staked closer to the ground to protect against the wind.

The catenary cut makes it easy to pitch this tarp very tight to resist the wind. The ability to set it up low against the ground, while still having headroom to sit, is a significant advantage in foul weather compared to smaller tents that don't allow as much headroom. In exposed sites, it can be important to pitch one end of the tarp near a rock or bush that blocks the wind. Alternately, you can block the open foot with your backpacks and partially cover the head end with a rain jacket. If you know you are going to face bad weather, or for the greatest protection and safety for long journeys, pairing this with a lightweight water resistant bivy sack is a good idea. The fixed set up with two open ends meant we couldn't rate this tarp as high as the Hyperlite Mountain Gear Square Flat Tarp, which can be set up in storm mode, but we felt it was much better than the MSR Flylite 2.

Livability


The Grace Tarp Duo is a LARGE A-frame tarp. It is much larger than the Hyperlite Mountain Gear Square Flat Tarp. The added coverage is important for comfort in high winds and downpours because it provides lots of space for two people and their gear, even when the tarp is pitched tight against the ground. Depending on steepness of pitch, we had about four inches overhead at the peak for our 5'11'' testers when we pitched the Grace low to the ground for maximum weather protection. That's a lot more headroom than most tarps would afford.

Pitching this shelter between trees takes a little longer than using trekking poles  but frees up more livable space at the front entrance. We love the large size  even with the sides staked right down to the ground  there's plenty of headroom for 5'11" Brandon to sit inside the front entrance.

This tarp also has three plastic clips on the underside of the ceiling. A mesh inner tent with bathtub floor can hang from these, or they can be used to rig up a clothes line, or for other gear storage. Without adding a modular inner tent, like the Serenity Bug Net Shelter ($205, 16oz. for Duo SilNylon), there is no bug protection or floor. And regardless there will not be much privacy with this tarp. With these thoughts in mind, we ranked it near the bottom in livability, roughly the same as the Big Agnes Fly Creek HV2 Platinum.

There are three little plastic rings sewn into the eave of the Grace Tarp that can serve as clips for hanging a modular net tent  or for setting up a close line if you need to dry out your socks.

Weight


At a measly 15.1 ounces for our SilNylon version, the Grace Tarp Duo is the second lightest shelter in this review, second only to the DCF HMG Square Flat Tarp. If you want the lightest version of this tarp, then upgrading to DCF is possible for an extra $130. The SilNylon tarp itself weighs in at only 12.4oz. and the 40' of included 2.7mm guy line weighs only 2oz. It also comes in a SilNylon stuff sack that is unfortunately far too large for the Duo, meaning that it fits easily, but could fit in a far smaller stuff sack that would be more efficient for packing. In order to complete the setup you need to add two adjustable trekking poles (or buy the carbon fiber poles available from MLD), and eight stakes.

The Grace Tarp comes with line locks sewn in place  and an uncut piece of cord for you to slice up to your own desires. Unfortunately  the SilNylon sack  shown  is far larger than it needs to be  and this tarp could easily be stuffed into a small sack half the size -- one you will have to buy on your own! You will need to add two adjustable trekking poles and a minimum of six stakes to this setup.

Adaptability


A-frame tarps offer an advantage over traditional tents and pyramid shelters in that the pitch can be adjusted in both height and width. If a campsite is narrow you can bring the walls in and pitch it tight against the ground, something that you can't do with the fixed size of the Six Moons Designs Haven Tarp. Raise it up and spread it out for more headroom and coverage if you don't anticipate any wind. However, flat tarps are much more versatile because their pitching configurations are limited only by your imagination. The Grace Tarp Duo is a great tarp for most backpacking environments, but if you want to become an expert tarp camper, or want to travel as light as possible in the most exposed and rugged areas, we highly recommend our favorite ultralight tarp, the Hyperlite Mountain Gear Flat Square Tarp.

Here is the tarp component of the Echo II Shelter made by Hyperlite Mountain Gear  tensioned over the top of the this model. As you can see  the true Duo size of the Grace provides significantly more coverage.

Ease of Set-up


The Mountain Laurel Designs Grace Tarp Duo, due to its generous catenary cut at the ridgeline, is the easiest to set up A-frame tarp that we have tested. All things considered, we find it about the middle of the pack for ease of set up, roughly the same as the Hyperlite Mountain Gear UltaMid 2 or the Nemo Hornet 2P. Our first pitch in the backyard took right about four minutes with adjustable trekking poles. Four minutes is a good set-up time for one person, and two can do it faster. Forty feet of cord for staking and guying out is included, but must be cut and added to the Line-Locks, preferably before you are out in the field. We found set-up using trekking poles quicker than pitches where the ridge lines were secured to trees.

Sewn in grommets at each end of the eave make it very quick and easy to insert your pole tip  and then tension out the tarp. This setup is much faster and easier than needing to tie off your poles individually  making this a quick setup for the practiced rigger.

One feature that really added to the simplicity of set up was grommets sewn into the tabs at each end of the ridge crest, which easily took the tip of our adjustable trekking poles, and are also designed to accept the end of carbon fiber poles that are sold separately. This was a faster and simpler method of rigging poles than needing to tie clove hitches, like we do to set up the Square Flat Tarp.

Best Applications


The Grace Tarp is perfect for ultralight backpacking and thru-hiking on a budget. If you seek three-season protection in an affordable ultralight shelter, this one is hard to beat. It is also a good option for those who prefer tarps but aren't carrying trekking poles, as carbon fiber poles can be purchased for only $50.

On a relatively calm evening where no rain is expected  we set up the Grace Tarp high above the ground in the Sangre de Cristo Mountains of Colorado before an epic peak bagging session the next day.

Value


At a mere $165 for the Duo size, this is hands down the most affordable shelter in this ultralight review. We think the quality of materials used and the construction is excellent, so of course we think this shelter presents a great value.

Conclusion


The Mountain Laurel Designs Grace Tarp is a very large, catenary cut shaped tarp that comes in either SilNylon (cheaper) or DCF (more expensive) versions. While it doesn't provide the same level of weather resistance as pyramid or dedicated pole tents, it still offers generous coverage for a tarp, and set up in sheltered places will easily protect the user in all but the windiest rain storms. It is the most affordable shelter in this review, presenting a great value, and is also quite easy to set up for a tarp. If light weight and affordability are primary concerns, we encourage you to check out this high quality tarp.

This SilNylon A-frame tarp is larger than most 2-person tarps; MLD calls it 'true duo' size. The generous dimensions create more headroom when pitched close to the ground for wind-driven rain protection. Vedauwoo  WY.
