Marmot Limestone

What capacity tent do you need?  

• How many are in your group? Tents vary in size from 2- to 8-person. 
• Assume a close fit for the number of people your tent is designed to accommodate. If you need more space for dogs and gear, size up. 

Choose the seasonality 

• 3-season tents are great shelters for most of the year. They have ample mesh for good airflow and can withstand basic downpours. 
• 3+- season tents are a little sturdier, and with less mesh, and are warmer than their 3-season cousins. 
• 4-season tents are engineered to handle high winds and other severe weather. This can make them stuffy in warm weather. 

Decide on key features 

• Peak height: Look for a taller peak height if you want to stand up in the tent.  
• Floor length: Can you fully lie down if you’re tall? Will it fit your cot or air mattress? 
• Doors: If multiple people are sleeping in the tent, you might want more than one door for more convenient access. 

Liner uses

• Backpacking: A mummy-shaped liner can add 5° to 15°F of warmth to your bag. It also helps your bag last longer by protecting it from dirt and body oils.

• Traveling: A rectangular liner separates you from unclean bedding. 

Liner materials

• Silk: Very light, compact and insulates in cold weather. Absorbent and breathable in warm weather. Price: moderate to expensive. 
• Cotton: Strong, durable, absorbent. Not the lightest or most compact. Price: economical. 
• Fleece and microfleece: Warmer, heavier, soft, moisture-wicking, quick-drying. Mid- and heavyweight varieties are bulky. Price: moderate. 
• Synthetics: Moisture-wicking, breathable, stretchy. Price: moderate. 
• Insulated: Adds enough warmth to greatly extend the temp range of a lightweight bag. Price: moderate to expensive. 

Understand temperature ratings
Opt for a sleeping bag with a temperature rating below the lowest nighttime temperature you expect when camping.

Choose a sleeping bag shape
There are four main shapes: rectangular, semirectangular, mummy and double. For camping, you want one that gives you room to stretch.

Decide between synthetic or down insulation

• Synthetic is more affordable, dries faster and provides warmth when damp.
• Down is lightweight, durable and compresses small.

Other features to consider
A waterproof shell, snug-fitting hood, extra zippers and even a stash pocket can add durability, warmth and function.
