## Types of Military Surplus Sleeping Bags

Before diving into specific models, it’s helpful to understand the different types of military surplus sleeping bags you might encounter.

* **Mummy Bags:** These are designed to fit snugly around your body, maximizing warmth and minimizing dead air space. They often feature a hood that can be cinched down for added insulation.
* **Rectangular Bags:** More spacious and comfortable than mummy bags, rectangular bags offer more room to move around. However, they may not be as efficient at retaining heat.
* **Modular Sleep Systems (MSS):** These systems typically consist of multiple bags that can be combined to provide different levels of warmth, depending on the conditions. The US Military MSS is a very common and versatile option.
* **Bivy Sacks:** While not technically sleeping bags, bivy sacks are often used in conjunction with sleeping bags to provide an extra layer of protection from the elements. They are lightweight and packable, making them ideal for backpacking.

## Buying Guide: What to Look For in a Military Surplus Sleeping Bag

Choosing the right military surplus sleeping bag can be tricky, especially if you’re not familiar with the different types and features available. Here are some key factors to consider:

### Temperature Rating

The temperature rating is one of the most important factors to consider when choosing a sleeping bag. Make sure the bag is rated for the lowest temperature you expect to encounter on your trip. Remember, temperature ratings are often based on survival, not comfort. So, if you tend to get cold easily, it’s best to choose a bag with a lower temperature rating than you think you need.

### Condition

Military surplus gear can range in condition from “like new” to “heavily used.” Be sure to carefully inspect the bag before you buy it to make sure it’s in good working order. Look for tears, rips, or other damage that could compromise its performance. Also, check the zippers to make sure they’re functioning properly.

### Material

The material of the sleeping bag will affect its durability, weight, and warmth. Look for bags made from durable materials like nylon ripstop or polyester. These materials are water-resistant and can withstand a lot of wear and tear. The fill material is also important. Down is warmer and more compressible than synthetic fills, but it’s also more expensive and doesn’t perform as well when wet. Synthetic fills are a good option if you’re on a budget or if you expect to encounter wet conditions.

### Weight and Packability

If you’re planning on backpacking or hiking, weight and packability are important considerations. Look for bags that are lightweight and can be compressed down to a small size. Mummy bags are generally more compact than rectangular bags.

### Size and Fit

Make sure the sleeping bag is the right size for your body. If it’s too small, you’ll feel cramped and uncomfortable. If it’s too big, you’ll have extra dead air space that will make it harder to stay warm. Mummy bags are typically sized by height, while rectangular bags are sized by width.

### Features

Consider any additional features that might be important to you, such as a hood, draft collar, internal pockets, or a two-way zipper. A hood can add extra warmth in cold conditions, while a draft collar can help to prevent heat loss around your neck. Internal pockets are useful for storing small items like your phone or wallet. A two-way zipper allows you to vent the bag from the bottom, which can be helpful if you get too warm.

## Caring for Your Military Surplus Sleeping Bag

Proper care and maintenance will extend the life of your military surplus sleeping bag and ensure that it continues to perform well. Here are some tips:

* **Wash it properly:** Follow the manufacturer’s instructions for washing your sleeping bag. Down bags should be washed with a special down soap and dried on low heat with dryer balls to prevent clumping. Synthetic bags can be washed with a mild detergent and dried on low heat.
* **Store it properly:** Store your sleeping bag in a loose, breathable bag when you’re not using it. This will help to prevent mildew and maintain its loft. Avoid storing it in a compression sack for extended periods, as this can damage the fill material.
* **Air it out regularly:** Air out your sleeping bag after each use to remove moisture and odors. Hang it outside in the sun or in a well-ventilated area.
* **Repair any damage:** Repair any tears or rips as soon as possible to prevent them from getting worse. Use a patch kit or take it to a professional for repairs.
