Dry Sack Pump Sea To Summit Air Stream Orange 48g

The Sea To Summit Air Stream Dry Sack Pump in orange is a multipurpose 20 litre inflatable pump and dry sack designed to speed up inflation of sleeping mats and protect gear from moisture. At 48 g and made from lightweight 15D Ultra-Sil®, this Air Stream model combines a compact pack liner with a pump that delivers large volume airflow. Its oval base and fully seam-sealed construction with a sealable valve plug permit use as either a dry sack or an ultralight pack liner while providing reliable water protection for clothing and sleeping systems.

Advantages

The Air Stream inflates most sleeping mats in only two or three compressions, reducing breath condensation inside mats and lessening user fatigue compared with manual mouth inflation. The oval base design improves stability during use and makes it easier to compress air efficiently. Fully seam-sealed construction with a sealable valve plug keeps contents dry when used as a dry sack. Weighing 48 g and constructed from 15D Ultra-Sil®, the pump balances durability and minimal weight for backpacking and travel.

Suitable for

• Inflating sleeping mats and air mattresses while camping or backpacking
• Use as a 20 L dry sack to protect clothing and electronics from moisture
• Ultralight pack lining to organize and waterproof gear inside a backpack
• Rapid inflation in cold or high-altitude conditions to reduce breath condensation

Key specifications

• Volume: 20 litres
• Weight: 48 g
• Material: 15D Ultra-Sil®
• Shape: oval base for stable compression

How to use

Open the sealable valve plug and use the Air Stream as an inflated air reservoir by compressing the sack two to three times against the sleeping mat valve until the mat reaches the desired firmness. Alternatively, fully inflate the Air Stream with a single breath before transferring air to very large-volume mats. When used as a dry sack or pack liner, place items inside, close the valve plug and roll or fold the top to seal. Check the valve plug is properly seated to maintain a waterproof seal.

Usage recommendations

For fastest inflation, align the Air Stream outlet with the sleeping mat valve and use firm, even compressions. Avoid over-inflating sleeping mats; stop when the mat feels comfortably supportive. When used as a dry sack, rinse and dry the sack after exposure to saltwater and store folded away from direct sunlight to prolong the 15D Ultra-Sil® fabric life.
