Underquilts for Cold Weather: Stay Warm Hammock Camping
Underquilts for Cold Weather: Stay Warm Hammock Camping
Hammock camping is a fantastic way to connect with nature, offering a unique and comfortable outdoor experience. However, one of the biggest challenges is staying warm, especially in colder temperatures. Unlike traditional ground camping where your sleeping bag compresses its insulation underneath you, a hammock allows cold air to circulate. This is where an underquilt comes in – it’s a crucial piece of gear for comfortable, cold-weather hammock camping.
An underquilt is essentially a sleeping bag designed to hang *under* your hammock, providing insulation from below. It prevents heat loss caused by compression and air circulation, keeping you cozy throughout the night. This article will delve into the factors to consider when choosing the best underquilt for cold weather, covering insulation types, shapes, temperature ratings, and more.
Understanding Insulation Types
The core of any underquilt is its insulation. Two primary types dominate the market: down and synthetic. Each has its pros and cons.
Down Insulation
Down is renowned for its exceptional warmth-to-weight ratio. It’s incredibly compressible, making it ideal for backpacking. High-quality down (measured in fill power) traps a significant amount of air, providing excellent insulation. However, down loses its insulating properties when wet. While treated down options are available, they still require careful protection from moisture.
Synthetic Insulation
Synthetic insulation, such as PrimaLoft or polyester fibers, retains its warmth even when damp. It’s generally more affordable than down and easier to care for. However, it’s bulkier and heavier for the same level of warmth. Modern synthetic insulations have significantly improved in recent years, closing the gap in performance with down.
Underquilt Shapes and Coverage
The shape and coverage of an underquilt significantly impact its effectiveness. Here are the common options:
Full Underquilts
These provide complete coverage underneath the hammock, offering the most warmth. They typically have a curved or asymmetrical shape to eliminate cold spots. Full underquilts are ideal for colder temperatures and longer camping trips.
Partial Underquilts (Bridge Quilts)
Bridge quilts cover the area between your back and the hammock, reducing drafts and providing a noticeable warmth boost. They are lighter and more compact than full underquilts, making them a good choice for milder temperatures or when weight is a concern. They often work well in conjunction with a top quilt.
Brazilian Quilts
Brazilian quilts are a hybrid design, offering a balance between full and partial coverage. They wrap around the ends of the hammock, providing good insulation without the bulk of a full underquilt. They are a versatile option for a range of temperatures.
Temperature Ratings and Considerations
Underquilts are rated based on the lowest temperature at which they are expected to keep you comfortable. However, these ratings are subjective and depend on several factors, including your metabolism, clothing, and the specific conditions. It’s generally advisable to choose an underquilt rated for a temperature lower than what you anticipate encountering.
Consider these points when evaluating temperature ratings:
- EN/ISO Ratings: Look for underquilts tested to EN or ISO standards for more reliable comparisons.
- Your Cold Tolerance: If you tend to sleep cold, opt for a warmer rating.
- Layering: You can always vent an underquilt if you get too warm, but you can’t add warmth if it’s not there.
Suspension Systems and Features
How an underquilt attaches to your hammock is crucial for its performance. Common suspension systems include:
- Suspension Straps: These are adjustable straps that wrap around the hammock suspension.
- Whoopie Slings: Lightweight and highly adjustable, whoopie slings offer precise control over the underquilt’s position.
- Buckles: Simple and easy to use, buckles provide a secure attachment point.
Other features to consider include:
- Draft Collars: These help seal the gap between the underquilt and your hammock, preventing drafts.
- Baffles: Baffles keep the insulation evenly distributed, eliminating cold spots.
- Storage Sack: A compression sack makes it easier to pack the underquilt.
Choosing the Right Underquilt: A Summary
Selecting the best underquilt for cold weather hammock camping requires careful consideration of your needs and preferences. Here’s a quick recap:
- Temperature: Match the underquilt’s rating to the expected conditions, erring on the side of warmth.
- Insulation: Down offers superior warmth-to-weight, while synthetic provides better performance in damp conditions.
- Shape: Full underquilts provide the most warmth, while partial quilts offer a lighter, more compact option.
- Suspension: Choose a suspension system that is easy to use and provides a secure attachment.
Investing in a quality underquilt is essential for enjoying comfortable and safe hammock camping in cold weather. By understanding the different options available, you can choose the perfect underquilt to keep you warm and cozy all night long.
Frequently Asked Questions
What temperature underquilt do I need?
The temperature rating depends on your personal cold tolerance and the expected conditions. As a general rule, choose an underquilt rated 10-15°F lower than the lowest temperature you anticipate. Consider layering with additional clothing if needed.
Can I use a regular sleeping bag as an underquilt?
While technically possible, a standard sleeping bag isn’t designed for the compression and airflow of a hammock. The insulation will be compressed, reducing its effectiveness. An underquilt is specifically designed to wrap around the hammock and maintain its loft.
What’s the difference between a top quilt and an underquilt?
A top quilt goes *over* you, providing insulation from above, similar to a sleeping bag. An underquilt goes *under* the hammock, insulating you from below. Both are essential for cold-weather hammock camping.
How do I properly hang an underquilt?
Ensure the underquilt wraps completely around the underside of your hammock, with no gaps. Adjust the suspension system to achieve a snug fit and eliminate drafts. A properly hung underquilt should have a slight sag to maintain its loft.
Are down underquilts worth the extra cost?
Down underquilts offer a superior warmth-to-weight ratio, making them ideal for backpacking and situations where weight is a concern. However, synthetic options are more affordable and perform better in wet conditions. The best choice depends on your budget and priorities.
