The Shadow Mountain is an inflatable sleeping pad from Sierra Designs that, with a 1.3 R-Value, is specifically designed for warmer temperatures, unless pairing with a CCF (Closed-Cell Foam) pad. This compact product inflates and deflates quickly, and is ideal for beginner to intermediate overnight hikers who are on a budget. This sleeping pad could also be an ideal product for young campers! Note: This sleeping pad is not ideal for users above ~150lbs, or restless sleepers.
- Deflates/packs very quickly
- Interesting stow bag
- Comfort—Ground contact occurs when moving/sitting up
- Low R-Value makes it less versatile
Sierra Designs has been innovating apparel and outdoor gear since 1965, providing quality products to outdoor enthusiasts worldwide. The company currently has two offerings for sleeping pads, the Shadow Mountain and the Granby (insulated version of this pad). Trailspace's own LoneStranger reviewed the new Granby pad, which can be found here.
Sleeping pads are a new addition to the Sierra Designs line. At the price point of $79.95, the Shadow Mountain will suffice for most of the weekend-warriors that go backpacking in mild weather, or car-camp. Outside of these conditions, this sleeping pad rings in on the heavy and cold side.
- Price: $79.95 USD
- Gender: Unisex
- Dimensions: 72" x 20" x 3" (4" x 9" packed)
- R-Value: 1.3
- Weight: 14.5 oz (16 oz without storage bag recorded)
- Fabric: 20D Nylon
- Included stuff sack
The Shadow Mountain sleeping pad inflates/deflates very easily, thanks to an easy-to-use valve system. Both plugs simply press into their cylinders, and are permanently attached to the sleeping pad.
The Shadow Mountain sleeping pad fully inflates with approximately 8-10 breaths, however is not compatible with any inflation sacks.
There is a one-way check valve for easy inflation. With the valve open, the sleeping pad deflates quickly.
Rolling up the pad for storage is effortless, without the need to struggle removing trapped air. Sierra Designs includes a "Burrito Bag," a practical storage bag unlike most storage sacks one will find on the market today.
The Burrito Bag is like a typical stuff sack, however the drawstring is sewn the circumference of the entire length of the bag.
Sierra Designs boasts that "a 3" thickness means you'd be hard pressed to find the ground." Although the sleeping pad does indeed measure 3 inches when fully inflated, ground contact is frequently made when changing sleeping positions during the night. One's backside fully contacts the ground when sitting up, which is a disappointment from such a reputable brand.
It should be noted that the pad is being tested by a 5'10", 160-pound user. With Earth-lift being such a vital necessity with a sleeping pad, this concern is the primary basis for evaluating this product as "less-than-stellar."
Until design improvements are made, this pad is not ideal for light sleepers that toss and turn frequently. Pleasant nights testing this product have felt unnecessarily long.
Construction & Durability
This sleeping pad is constructed of a 20D Nylon using a grid style of chambers. Since the grid is not offset, it takes a bit of getting used to.
Sierra Designs suggests the Shadow Mountain "pairs well with 35°F bags" and promises to "deliver comfort in a lightweight, compact package."
This being said, by constructing the pad with a low 1.3 R-Value this is a summer pad not designed for use at or below 35°F. Pairing the Shadow Mountain with a Therm-A-Rest RidgeRest SOLite pad, temperatures down to approximately 18°F have provided sufficient insulation. Sierra Designs claims that the pad 'Pairs well with 35°F bags'- the brand's claims are likely accurate.
This pad has been tested in conjunction with several insulation setups—an REI Travel Down 45°F sleeping bag, a Double Black Diamond Down Blanket with a Sea To Summit Thermolite Reactor Sleeping Bag Liner, and a Rab Alpine Summit 20°F down sleeping bag with a Therm-A-Rest RidgeRest SOLite CCF (Closed-Cell Foam) pad.
Testing over the last six months (12 overnights) has shown no signs of wear. Typical of most Sierra Designs products, construction is very high quality.
The Shadow Mountain sleeping pad has been tested since May 2020 in the mid-Atlantic East Coast, USA, area, as well as an autumn trip in Maine. This pad has been used on several overnights on the Appalachian Trail, an AT section hike, and a week-long lean-to loop in Baxter State Park, ME. Temperatures have ranged from the upper teens to approximately 65°F.
Sierra Designs has made quality shelters for years, and it is good to see that they are branching out beyond the tent and apparel market. Although the Shadow Mountain sleeping pad has plenty of headroom for improvement, this product is still a potential contender at its lower price-point. Hopefully Sierra Designs will look further into the R&D of this pad to correct the ground contact concern that hinders this product from being a great product. At this point, this sleeping pad is best suited for lighter users, or people that tend to move less when sleeping.
Many thanks to the people at Sierra Designs for the opportunity to test the Shadow Mountain Sleeping Pad for the Trailspace Gear Review Corps!
After making the transition to air-inflated sleeping pads approximately three years ago, this has become a first choice when it comes to ground sleeping. After decades of using infallible CCF (Closed-Cell Foam) pads, a tired and aching back has not looked back, other than to double-up in winter temperatures, or for hammock sleeping.
