Sea to Summit eVac compression dry bag, HIghRise Grey, 5 Liter — waterproof, valve-free compression for backpacking

This compact dry bag combines a roll‑top closure and an air‑permeable base to let air out but keep water out, giving you a lower‑profile, more organized pack. Built from bluesign‑approved lightweight PU‑coated 70D nylon and a 40D air‑permeable/waterproof base, it’s designed for backpackers, paddlers, and campers who need tough, compressible waterproof storage without extra bulk.

How does the eVac design shrink bulky gear for easier carrying?

The eVac uses a valve‑free, air‑permeable base so you can squeeze air out through the bottom after sealing the roll‑top. Compression straps then lock the bag down into a tighter, oval shape that resists rolling inside a pack or boat.

• Roll the closure three times to seal and start compression
• Push down on the bag to force air out through the specialized base
• Four compression straps with ladderlock and side‑release buckles tighten evenly

Will this dry bag really keep my gear dry on wet trips?

The fabric has a 10,000 mm waterhead rating and fully taped seams, so it provides a high level of water resistance in rain, splashes, and wet pack conditions. The roll‑top closure and sealed seams together create a waterproof barrier; the base’s material permits airflow while remaining water‑resistant under normal use.

• 10,000 mm waterhead fabric for strong waterproof performance
• Double‑stitched seams sealed with waterproof tape
• Roll‑top closure prevents water entry at the opening

How durable and repairable is the eVac for long trips?

Sea to Summit built the eVac from rugged nylon with reinforced seams and a patent‑pending field repair buckle you can swap in seconds. The low‑profile shape and oval base reduce abrasion points, and interior reflective lining helps you locate items without dumping the bag out in the dark.

• PU‑coated 70D nylon body for durable, lightweight protection
• Reinforced seams with tape sealing for long‑term reliability
• Replaceable field repair buckle for quick on‑trail fixes

What size and weight should I expect from the 5‑liter model?

The compact 5‑liter eVac fits small kits and compresses down to a slim profile so it won’t dominate pack space or weight allowances. It’s sized for small clothing items, electronics in dry pouches, or food for one person, weighing just a few ounces for minimal carry impact.

• Closed dimensions: approximately 6.5 x 5.8 x 12.3 inches
• Volume: 5 liters when rolled three times closed
• Weight: about 0.22 pounds (light, packable)

Who is this for? If you need weather‑resistant, space‑saving storage for backpacking, canoeing, bikepacking, or travel, the Sea to Summit eVac 5L offers a balance of waterproof protection, compression performance, and lightweight materials. It suits outdoor enthusiasts who prioritize pack organization, quick field repairs, and dependable water resistance without bulky hardware.
