Compression Sacks in 5- to 35-Liter Sizes

Bring your sleeping bag, a weekend’s worth of clothes, and other stuffable gear down to size with Ultralight Compression Sacks from Outdoor Research. Made of durable, water-resistant siliconized fabric, it’s designed to slide into your pack with ease and hold up for many trips to come. At just 2 ounces for the 5-liter bag, it won’t weigh you down, and the internal pocket can be used to keep track of small items and doubles as a stuff sack.

Note: This drop’s base price is for the 5L Ultralight Compression Sack in your choice of color: Alloy, Agate, or Lemongrass. At checkout, you can opt for the 8L (+ $1), 10L (+ $2), 15L (+ $4), 20L (+ $5), or 35L (+ $7) models in any of those three colors. You have the option to add a set of three Ultralight Ditty Sacks (+ $22).

Optional Ditty Sacks

Keep the contents of your pack neatly organized with these ditty sacks. The set includes three sacks in different colors and capacities (3, 4, and 6 liters), coming in between 0.6 and 0.8 ounces apiece. Each sack is made of 30d siliconized ripstop nylon, which offers water-resistance while keeping weight to a minimum, and features a drawcord cinch closure. Use them to store and carry everything you need for your next camping or backpacking trip—from granola bars and cooking utensils to sunscreen, sleep gear, and more.
