The consensus

What reviewers found

Synthesized across the trust-weighted source mix below.

Across the reviewers we read, the Unigear cover stands out for two specific design choices that recur across listings and a r/backpacks thread: an integrated stash pouch that clips to the pack and small bottom grommets designed to drain pooled water. That second feature directly addresses a complaint surfaced in a r/backpacking thread, where a high-trust commenter noted water pooling at the bottom of cinched covers is a major failure mode. Verified-purchase volume is moderate (4.6 stars across more than 1,100 reviews), and a r/backpacks recommendation thread specifically calls it out as a reasonable cover for a ULA Ultra Dragonfly pack.

What reviewers liked

  • Bottom grommets drain pooled water, addressing a documented failure mode in r/backpacking discussion
  • Integrated carry pouch clips to the pack for fast deployment
  • r/backpacks thread specifically recommends it for ULA pack owners
  • 4.6-star Amazon average across 1,100+ verified-purchase reviews

Where it falls short

  • 5,000mm waterproof rating is the lowest among the budget covers in this pool
  • r/Ultralight community is broadly skeptical of pack covers as a category
  • Sizing runs tight; reviewers recommend sizing up if between volumes
  • No reflective elements for commuter visibility

Across the reviews

Across the reviewers we read, the Unigear cover stands out for two specific design choices that recur across listings and a r/backpacks thread: an integrated stash pouch that clips to the pack and small bottom grommets designed to drain pooled water. That second feature directly addresses a complaint surfaced in a r/backpacking thread, where a high-trust commenter noted water pooling at the bottom of cinched covers is a major failure mode.

Verified-purchase volume is moderate (4.6 stars across more than 1,100 reviews), and a r/backpacks recommendation thread specifically calls it out as a reasonable cover for a ULA Ultra Dragonfly pack. The 5,000mm waterproof rating is lower than Joy Walker's claimed 12,000mm, but reviewers across the listings report it handles moderate-to-heavy rain in practice. Community debate, predictably, still includes the broader r/Ultralight question of whether a cover is the right tool at all versus a pack liner.

For buyers who care about the practical detail of where the water goes once the cover wets out, this is the most thoughtfully designed budget option in the pool.

Made of 70D and 210T Nylon, it causes the rain to bead up and run off the surface instead of soaking in backpack. Even if the water comes in the pack cover accidentally, the small metal hole on the bottom can help to flow quickly
Adjustable to Cover Your Backpack
Unigear rain cover features 2 vertical anti-slip buckle straps to adjust different backpack and pull the pack cover tight across the pack harness. Reinforce the elastic rim around your backpack to prevent sliding off. Comes in 5 sizes and colors to fit from 10L to 90L backpack
Packs into Its Own Mini Carry Pouch
Unigear backpack cover is ultraportable, tiny and saving space. Designed with double-sided zipper, it can be packed down into its own nylon pouch which attached to the pack cover. Don’t worry about losing the carry pouch again
