Frequently Asked Questions (FAQs)

1. Are nylon sleeping bags good?

Nylon, Polyester, Taffeta – found in the most basic bags, these materials are perhaps the least durable used. They are best for indoor or family oriented camping trips – i.e. nothing that will test the durability. They are, however, breathable and low-cost. Recommended for drier conditions.

2. For what conditions is the rectangular sleeping bag appropriate?

Rectangular sleeping bags are ideally suited for car campers, where bag warmth, weight and size are not as high a priority as they would be while backpacking in the backcountry. Comfort is the highest priority, and rectangular sleeping bags, with their roomy design, shine for this purpose.

3. Why is nylon good for sleeping bags?

Sleeping bags are made with fabrics like nylon, polyester, or ripstop, making the shell fabric quite slippery. Also, they are often finished with a durable water repellent, which helps to minimize the amount of moisture that the sleeping bag can absorb, keeping the sleeper warm and dry.

4. What are the three types of sleeping bags?

Sleeping Bag Types Bags fall into three basic categories: summer, three-season, and winter. Summer bags are suitable for temperatures of about 30°F and higher. They're lightweight (because less insulation means less weight), and they pack down tiny (often as small as a cantaloupe).
