The Summerlite is worth the extra cost says many Western Mountaineering customers because of the super comfort, protection, and high-quality. It includes a draft tube that is single, meaning that the zipper will not touch the skin when a person is inside the bag. This is really important and appreciated when the temperatures are bitter cold, and the wind is blowing. Frigid air can usually seep through the tiny spaces in-between the metal zipper teeth and cause a draft to the interior. You would not think that such small spaces could allow cold air inside, but just ask anyone who has ever slept in freezing temperatures in a traditional sleeping bag. They will tell you that just a small draft from the zipper can keep you from being warm and contented. This will not happen with the Summerlite because of this incredible draft tube. The goose down filling is another comfort measure that Western Mountaineering has engineered into this fabulous sleeping bag. Sleeping bags filled with down have the best skin contact and coverage, and they drape well on the body. Their lightweight form will keep you so warm because of their ideal qualities.


What gives the Western Mountaineering sleeping bags their incredible durability and long-lasting outstanding performance is a layer of Durable Water Repellant (DWR) on the exterior. This layer will remain useful until about twenty washings. Then it is time to reapply this special coating to protect your bag as long as you have it. even with this coating, you should always use a waterproof ground cloth to protect the exterior as much as possible. This prime condition of this amazing sleeping bag will last longer if you do not leave it in a plastic bag or stuff sack for a long time. It must be properly dried out for the best storage. Snags are prevented in the zipper because of the stitched stiffening tape along the zipper adding to the durability and long life of the Summerlite. Fraying of the Velcro closures and the material is prevented by the fabric backing, plus the Velcro is placed on parts of the bag where it will be most out of the way, such as the casing of the drawcord. All of these extra measures taken by the manufacturer add to the longevity and usefulness of the product.

Western Mountaineering wanted to create a sleeping bag that still had the same function and quality features as their regular high-quality bags but in a much lighter form.

The fabulous Summerlite sleeping bag protects to 32 degrees in temperature because the draft tube is well insulated, and the bag is fully baffled. It includes a four-inch loft that protects in the most frigid and windy environments with ten ounces of down filling.

Every part of your body will be protected when you are inside this impressive sleeping bag.

This mummy-style sleeping bag does take some precautions to keep it lasting a long time in great condition, but the directives are simple and easy to follow. You should always use a ground cloth that is waterproof before placing any Western Mountaineering bag on the ground. Especially if the area is moist or wet, you should not place this top-quality bag directly on the ground surface. It has a defensive covering to protect the outer shell, so you may think that this is enough. You would be wrong. Even with the shielding layer, the bag needs to be cared for in the best way. the particular style of the mummy bag and the quality materials make this necessary. You can protect the inside of the sleeping bag by always wearing at least shorts, socks, and a t-shirt, which will act as a sheet in the interior. In storing the bag in the storage sack, this specific style requires that it be breathable. Before storing the bag, be sure to either air dry it in the sun or dry in a dryer on tumble first. It must be hand washed or cleaned in a machine that is a front loader. A top loading machine will ruin the construction of the baffle, and the soap used should be specifically for down products. There are natural oils in the down that will be destroyed by the cleaning fluids of a dry cleaner so do not bring it there to be cleaned. With these precautionary steps, your Summerlite bag should last for many years of comfortable sleeping in the great outdoors.
