Its durable, waterproof construction ensures that your clothing or sleeping bag remains protected from moisture inside your pack, while the intuitive design allows for rapid inflation of compatible sleeping pads. The lightweight materials used in its production ensure that you do not add unnecessary bulk to your load, maintaining the efficiency required for long-distance trekking and mountaineering.

Suitable for

• Waterproof storage for clothing and sleeping gear
• Backpacking and thru-hiking
• Camping trips where weight reduction is a priority

When it may not be suitable

This pump sack is specifically designed for compatibility with Therm-a-Rest sleeping pads. It may not be suitable for use with sleeping pads from other manufacturers that utilize different valve systems or inflation mechanisms.

Key specifications

• Dual-purpose inflation and storage functionality
• Waterproof material construction
• Lightweight and packable design
• Compatible with standard Therm-a-Rest valves

How to use

To use the device as a pump, simply attach the nozzle of the sack to the valve of your sleeping pad. Open the top of the sack to capture air, roll the top down to force the air into the pad, and repeat the process until the desired firmness is achieved. When used as a storage bag, place your items inside, roll the top closure down at least three times, and secure the buckle to create a watertight seal.

What to consider before purchase

• Check your sleeping pad valve type for compatibility
• Consider the volume of gear you intend to store inside
• Evaluate the weight savings compared to traditional pump methods

Usage recommendations

Always ensure the valve connection is secure before beginning the inflation process to prevent air leakage. When using as a dry bag, ensure the roll-top closure is properly sealed to maintain waterproof integrity in wet conditions.
