3F UL Gear Exhaustable Compression Sacks – Ultralight Dry Bags for Backpacking, Travel, Camping (12L/24L/36L)

Efficient, waterproof compression for outdoor gear

Meet the 3F UL Gear Exhaustable Compression Sacks, a lightweight, weather-ready solution designed for backpacking, camping, and travel. Built from tough waterproof materials, these sacks help keep clothing, sleeping bags, and electronics dry while staying easy to compress and pack into tight spaces.

The standout feature is a space saving design with a manual exhaust valve that lets you vent air and compress contents to one third or less of their original volume. This makes it easier to fit bulky gear into your pack on longer trips or when overhead compartments are tight on transit.

Durable materials and thoughtful construction

Choose between two material options that balance waterproofing and resilience. The 15D nylon variant includes a silicone coating for superior waterproofing and durability, while the 210T polyester taffeta version is thicker and offers strong abrasion resistance. Both are lightweight and designed for reliable use in varied outdoor conditions.

• Space-saving design with an exhaust valve for quick air removal
• Durable bottom venting valve, bottom hook, carabiner, and 500D TPU webbing for protection against wear
• Lightweight, wear-resistant construction suitable for backpacking, trekking, hiking, hunting, fishing, and skiing
• Weather-ready storage to keep warm clothes, towels, and electronics dry when rain or humidity hits

Practical use and important notes

In wet environments, the sacks help you seal and compress items quickly, making it easier to organize gear and reduce bulk. They are designed to protect contents from moisture and dust while remaining flexible enough to accommodate compressed sleeping bags and clothing.

Note: the compression effect is temporary and may last about half an hour depending on temperature and item stiffness. Available sizes include 12L, 24L, and 36L, with color options like blue, gray, orange, and green to help you color-code gear.

Why choose these sacks

If you want a reliable, lightweight solution for organizing gear on outdoor adventures, these sacks offer practical benefits without promising guaranteed results. They are designed to improve packing efficiency and protect items in a variety of scenarios.
