Doubling as a stuff sack, the Sea to Summit Jet Stream Pump Sack employs a “concertina action” to make the inflation of a Sea to Summit sleeping pad (sold separately) highly efficient and keep potentially damaging moist air from reaching the interior of the mat.
On each up stroke, multiple one-way intake ports pull air into the interior of the pump and on the down stroke air is directed through a valve plug and into the sleeping pad at a volume that mirrors a lung’s worth of inflation.
The 30D Ultra-Sil construction is surprisingly durable and allows the pump sack to weigh in at a mere 1.5 ounces. A roll-top closure enables the pump to serve as a stuff sack for clothes, gear, or even the sleeping pad. NOTE: It will not accommodate any sleeping pad with a packed size that exceeds the 8.7” x 3.9” x 1” dimensions of the Jet Stream Pump Sack.
- Lightweight TPU base has finger loops to hold pump on to mattress
