As a long-time backpacker and outdoor writer, one of the most common questions I get is about packing. Specifically, people want to know how to lighten their load. A crucial first step in achieving that is understanding what is base weight. Your base weight is the weight of your backpack before you add food and water. It’s everything else – your tent, sleeping bag, clothes, cooking system, first-aid kit, and all the other essentials. Getting this number down is paramount to enjoying your time on the trail, and it directly impacts what best clothes for backpacking you’ll even be able to comfortably carry. A lighter base weight translates to more energy for enjoying the scenery, less strain on your body, and a more positive overall experience. This article will break down base weight, how to calculate it, and guide you through selecting the best clothing for backpacking, focusing on strategies for minimizing weight without sacrificing comfort or safety.
Why Does Base Weight Matter?
Think about it: the average person can comfortably carry around 20% of their body weight. Exceeding that consistently leads to fatigue, increased risk of injury, and a generally miserable trip. Reducing your base weight allows you to carry more food and water for longer trips, or simply enjoy shorter trips with less physical stress. It’s the foundation of a comfortable and sustainable backpacking experience. According to the National Park Service, proper preparation, including weight management, is critical for backcountry safety.
The Impact of Every Ounce
It’s easy to underestimate the cumulative effect of small weight gains. That extra can of beans, the heavier water bottle, the slightly bulkier jacket – they all add up. A good rule of thumb is to aim for a base weight under 20 pounds, and ideally closer to 15 pounds or even lower for experienced backpackers. This allows for a total pack weight (including food and water) of around 30-40 pounds, a manageable load for most people. REI’s Expert Advice section has excellent resources on calculating and reducing pack weight.
Calculating Your Current Base Weight
The first step is to know where you stand. Here’s how to calculate your current base weight:
- Gather Everything: Lay out everything you typically take backpacking.
- Weigh Each Item: Use a kitchen scale or a dedicated backpacking scale to weigh each item individually. Don’t skip anything – even small items like your toothbrush and headlamp.
- Record the Weights: Create a spreadsheet or use a backpacking weight tracking app (there are many available for smartphones).
- Total It Up: Add up the weights of all the items. This is your current base weight.
Be honest with yourself! It can be eye-opening to see just how much weight you’re carrying. Once you have a baseline, you can start identifying areas for improvement.
Choosing the Best Clothes for Backpacking: A Weight-Saving Strategy
Clothing is often a significant contributor to base weight. Selecting the best clothes for backpacking requires careful consideration of layering, material, and versatility. The goal is to stay comfortable in a variety of conditions without carrying unnecessary bulk.
The Layering System
The layering system is the cornerstone of backpacking clothing. It allows you to adapt to changing weather conditions by adding or removing layers as needed. Here’s a breakdown:
- Base Layer: Moisture-wicking fabrics like merino wool or synthetic materials are essential. Avoid cotton, which stays wet and can lead to hypothermia.
- Mid Layer: Provides insulation. Fleece or a lightweight down jacket are good options.
- Outer Layer: Waterproof and windproof shell jacket and pants.
Material Matters: Prioritizing Lightweight and Quick-Drying Fabrics
The materials you choose significantly impact weight and performance. Here’s a comparison:
| Material | Weight | Dry Time | Pros | Cons |
|---|---|---|---|---|
| Cotton | Moderate | Very Slow | Comfortable when dry | Heavy when wet, slow drying, poor insulation |
| Merino Wool | Moderate | Moderate | Excellent moisture-wicking, odor-resistant, warm even when wet | More expensive, can be slower drying than synthetics |
| Synthetic (Polyester, Nylon) | Light | Fast | Lightweight, quick-drying, durable | Can retain odors, less warm than wool |
| Down | Very Light | Moderate (requires proper care) | Excellent warmth-to-weight ratio | Loses insulation when wet, requires careful cleaning and storage |
For most backpacking trips, a combination of merino wool and synthetic fabrics offers the best balance of performance and weight. Down is excellent for cold-weather trips, but requires extra care to keep it dry.
Essential Clothing Items (and how to minimize weight)
Here’s a suggested clothing list for a 3-season backpacking trip, with a focus on weight reduction:
- Hiking Shirt: 1 lightweight, moisture-wicking shirt.
- Hiking Pants/Shorts: 1 pair of convertible pants (zip-off legs) or shorts and pants.
- Base Layer Top & Bottom: 1 set of merino wool or synthetic.
- Mid-Layer: 1 lightweight fleece or down jacket.
- Rain Jacket & Pants: Essential for protection from the elements.
- Underwear: 2-3 pairs of quick-drying underwear.
- Socks: 2-3 pairs of hiking socks (wool or synthetic blend).
- Hat & Gloves: Even in summer, bring a hat and gloves for cold evenings.
- Hiking Boots/Shoes: Well-broken-in and appropriate for the terrain.
Consider multi-use items. For example, your rain jacket can also serve as a windbreaker. Pack only what you need, and avoid bringing “just in case” items that you’re unlikely to use.
Beyond Clothing: Other Areas to Reduce Base Weight
While clothing is important, reducing base weight involves looking at all aspects of your gear.
The "Big Three"
These are the heaviest items in your pack and offer the biggest opportunities for weight savings:
- Backpack: Choose a lightweight backpack that fits properly.
- Tent: Consider a single-wall tent or a tarp shelter.
- Sleeping Bag/Quilt: Down is lighter than synthetic, but requires more care.
Other Weight-Saving Tips
- Cooking System: Use a lightweight stove and pot. Consider no-cook meals.
- Water Filter/Purifier: Choose a lightweight option.
- First-Aid Kit: Customize your kit to your specific needs and remove unnecessary items.
- Headlamp: A lightweight LED headlamp is essential.
- Toiletries: Minimize toiletries and repackage them in smaller containers.
The Leave No Trace principles also apply to weight reduction – minimizing your impact on the environment includes carrying out everything you carry in, and avoiding unnecessary packaging.
Final Thoughts on Base Weight and Backpacking Apparel
Understanding what is base weight and actively working to reduce it is a game-changer for backpacking. Choosing the best clothes for backpacking – lightweight, versatile, and appropriate for the conditions – is a key component of that effort. Remember to prioritize comfort and safety, but don’t be afraid to experiment with different gear and techniques to find what works best for you.
