Core features of the Marmot Trestles 15 sleeping bag
The Marmot brand is by no means new on the market, as the company has produced high-quality outdoor equipment for almost fifty years. So besides sleeping bags, you can also get a tent, a jacket, or hiking pants produced by the same manufacturer.
Also, you can choose between the brand’s synthetic bags like those from the Marmot Trestles series and down sleeping bags such as the Marmot Never Summer. The company offers sleeping bags for all types of weather conditions which enables you to choose the one that best fits the climate you live in.

Design and size
As a three-season sleeping bag, the Marmot Trestles 15 is designed to keep the sleeper comfortable even in damp weather conditions. This model has a SpiraFil LT insulation that weighs between 33 and 35oz depending on the size.
The manufacturer lets you choose between Short, Regular, Long, and Long X-Wide size options that all have different shoulder and hip grits. For instance, the shoulder grit on the Regular Mummy version of the Marmot Trestles 15 sleeping bag is 62 inches, while the hip grit is 57 inches.
There are three different bag shapes available, so you can either opt for the Semi-rectangular, Mummy, or Slim Mummy version of this sleeping bag. All versions of the Marmot Trestles 15 sleeping bag have a 47-inch footbox, as well as a 3D hood that keeps both your feet and your head warm.
Also, all Marmot Trestles 15 models have a two-way zipper that allows for easy access to the sleeping bag’s interior. This model is only available in the Cobalt Blue/Blue Night color and currently, there are no other color options.
Warmth and comfort
As we already mentioned, this sleeping bag has the SpiralFil LT insulation type that keeps you warm at temperatures higher than 15 degrees Fahrenheit, hence the label of a three-season sleeping bag.
Besides warmth, this insulation type also keeps the sleeper comfortable regardless of the position they are sleeping in, as the sleeping bag offers soft support for the entire body. The 3D hood is equipped with zippers that are sawn behind draft tubes which prevent the cold air from entering the sleeping bag.
The blanket bottom construction and the wave construction top provide both warmth and comfort to the user while unzipping the bag will ensure you receive the ventilation you need if you’re too hot. Unlike most mummy sleeping bags, the Marmot Trestles 15 grants you enough space to sleep comfortably.
However, you should keep in mind that this sleeping bag can be too warm for the summer especially if you are a hot sleeper. Read our guide to the best warm-weather sleeping bags if you think that this Marmot’s model may be too warm for you.
Weight and usability
One of the major downsides of synthetic sleeping bags is their weight, as they are heavier than down sleeping bags, which makes them a poor choice if you have to carry a lot of supplies with you.
The Marmot Trestles 15 sleeping bags weigh between 3lbs and 4lbs depending on the model, and despite being compressible their compressed volume is still 768ci. This means that a Marmot Trestles 15 sleeping bag is going to add a few pounds of weight to your backpack and it will take quite a bit of space.
Even so, this is one of the best sleeping bags you can get if you’re expecting to be sleeping in wet or damp weather conditions. The sleeping bags from the Trestles series are not water-proof but they dry quickly even if they get soaked.
These features enable you to use these sleeping bags in climates that range from dry and warm to cold and wet, but you should keep in mind that the Marmot Trestles 15 models are not designed for use in winter conditions.
All materials used to produce the Marmot Trestles 15 sleeping bags are considered durable, and there is very little chance that you can damage this sleeping bag even if you use it frequently. Also, using any of the models from the Marmot’s Trestles series in wet conditions won’t affect their durability.
The size and weight of sleeping bags make them only a good choice for short backpacking trips, since it may be difficult to carry a Marmot Trestles 15 bag at high altitudes for days. Chances are that you will be able to use this sleeping bag for years.
The Marmot Trestles 15 sleeping bags are machine washable which makes them easy to maintain. Read our guide to washing a sleeping bag to find out what you need to do in order to keep your sleeping bag clean.
Other noteworthy features
The Marmot’s Trestles 15 sleeping bags are stacked with features that are designed to provide maximum comfort to the sleeper.
So, besides excellent insulation capabilities, these sleeping bags are also highly functional as they feature zippers that glow in the dark which enables you to locate them during the night.
The stash pocket is located inside the sleeping bag which allows you to keep the necessities and valuables next to you. In case the Marmot Trestles 15 sleeping bag gets wet during the night you can use its hang loops to hang it and dry it.
All models of this sleeping bag come with a compression stuff sack, but you must purchase a storage sack separately.
The Marmot Trestles 15 doesn’t come with any additional accessories. What’s more the Marmot brand doesn’t produce sleeping mats that help you create separation between the sleeping bag and the ground.
You must purchase all accessories that will help you sleep better during your outdoor activities separately from the Marmot Trestles 15 sleeping bag.
Price and warranty
Models from the Marmot’s Trestles 15 series are affordable, as you can purchase them for less than $200. Their price depends on the sleeping bag model and its size but the price difference between different models isn’t too large.
All Marmot Trestles 15 sleeping bags are covered by the manufacturer’s limited lifetime warranty that enables you to replace a broken zipper or fix common defects. However, if the materials on your sleeping bag wear out over time, the manufacturer won’t offer you a free replacement.

The cons of the Marmot Trestles 15 sleeping bag
Heavy and bulky
The compressed size of Marmot Trestles 15 sleeping bags can make it difficult to find space for them in your luggage.

The best alternatives to the Marmot Trestles 15 sleeping bag
Backpacking and hiking enthusiasts can choose from a broad range of differently shaped and insulated sleeping bags that are designed for different weather conditions.
The Marmot Trestles 15 sleeping bags can be used from spring to autumn but some backpackers can find them too warm hot weather and too cold for rainy nights.
We’ve shortlisted a few alternatives to Marmot Trestles 15 sleeping bags so let’s take a look at what they have to offer.
Nemo Disco 15
Unlike the Marmot Trestles 15, the Nemo Disco 15 is a down sleeping bag which means that it is considerably lighter than any of the models from the Trestles series. This Nemo’s model weighs 2lbs and 10oz and it is available in sizes up to 6’6’’.
This is a spoon-shaped mummy sleeping bag that offers more sleeping room than conventional mummy models.
You can use these ISO and EN tested sleeping bags at temperatures higher than 15F, but you should keep in mind that they don’t perform well in humid wet, and damp weather conditions, despite having a 30D Nylon Ripstop Exterior shell with DWR and a 30D Nylon Taffeta lining.
The Nemo Disco 15’s hood is large enough to house a pillow and keep it in place while you’re sleeping. This lightweight sleeping bag is a perfect choice for long hiking or backpacking trips as it doesn’t require a lot of storage space, and you can use it in both cold and hot weather conditions.
RAB Mythic Ultra 180
In case you are looking for an ultra-lightweight sleeping bag that is designed for warmer temperatures, you should take a closer look at the RAB Mythic Ultra 180. This down sleeping bag weighs just 14oz due to the Super lightweight 7D Ripstop nylon that features the Thermo ionic lining technology.
The shape of this sleeping bag is trapezoidal which efficiently eliminates the cold spots. Despite these remarkable features the RAB Mythic Ultra 180 has a 32F sleep limit that makes it only suitable for use in warm climates.
Also, this RAB’s model is only available in regular size, and it may be too small for people taller than 6 feet. The sleeping bag has an anti-snag zip guard as well as an internal collar and hood that prevent cold air from reaching the interior of the sleeping bag.
The zipper is located on the left side of the sleeping bag and currently, there are no dual-zipper models in the RAB’s Mythic Ultra series.
Therm-a-Rest Vesper 45
The 900 fill Goose Nikwax Hydrophobic down insulation and 10D Nylon Ripstop shell with DWR are among the features that make Therm-a-Rest Vesper 45 an attractive option for hikers and backpackers that like to travel light.
This down sleeping bag weighs just 12 ounces and it is easily compressible to the size of 4.5 x 6 inches, but its sleep temperature limit is 40F. Hence, the Therm-a-Rest Vesper 45 is a poor choice if you live in a cold climate where temperatures are often below 32F.
This model is not water-proof although it absorbs 90% less water than similar down sleeping bags and it also dries much faster than sleeping bags with similar features. The Therm-a-Rest Vesper 45 is equipped with SynergyLink™ Connectors that enable you to attach this sleeping bag to a mat.
You can choose between Regular and Long sizes that can accommodate people shorter than 6’6’’.
Answer: Yes, you can. You just have to place the right zipper of one sleeping bag next to the left zipper of the second Marmot Trestles 15 sleeping bag. Also, you can zip these sleeping bags with any other model that is equipped with a YKK#5 zipper.
Answer: You will get a stuff sack with your Marmot Trestles 15 sleeping bag, but a storage sack must be purchased separately.
Answer: Although these sleeping bags perform well in wet or damp conditions they are not water-resistant and you shouldn’t leave them exposed to rain for a long time.
Answer: These three-season sleeping bags are designed to be used from spring until autumn, as temperatures can easily drop below 15F during winter.
Final Thoughts – Is the Marmot Trestles 15 a good choice for all backpackers?
The quality of the rest you get while camping or hiking largely depends on the sleeping bag you have. That’s why it is important to opt for a sleeping bag that provides you enough room to sleep comfortably and keeps you warm at the same time.
These sleeping bags are suited for both wet and dry weather conditions, while their insulation ensures that you’ll remain warm even if the temperature drops to 15F. A sleeping bag like the Therm-a-Rest Vesper 45 may be a better option for hikers and backpackers that live in warmer climates.
