Rainfly for Outdoor Backpack, 45L

Peak Design Rainfly for Outdoor Backpack — Gear Protection You Won’t Think Twice About

The gist: A purpose-built rain cover that ensures your laptop, hard drives, and work essentials stay dry whether you’re caught in a downpour on the way to a co-working space or commuting across a rainy city.

• 2,000mm waterproof rating: Terra Shell™ 50D recycled ripstop nylon with fully-taped seams provides serious protection for electronics and documents in sustained rain
• Drainage by design: Laser-cut drainage holes at the base prevent water pooling on the cover itself, so it comes off clean without soaking your bag
• No-fuss storage: Packs into an integrated zippered mesh pouch that lives in your bag — ready in seconds when weather turns, invisible the rest of the time
• Responsible materials: Bluesign-approved, PFAS-free, and Fair Trade Certified — aligns with the values remote professionals increasingly look for in everyday carry gear

Pack Hacker’s 7.7/10 review of the Outdoor Backpack 25L recommended the rainfly as a practical addition, noting the bag’s magnetic rolltop closure alone raised concerns about water infiltration — making this cover a sensible upgrade for anyone carrying mission-critical work gear.

Best for: Remote workers and daily commuters carrying laptops, external drives, or client materials who need reliable wet-weather protection at a low add-on cost. Skip it if: Your daily route is covered and you never find yourself in the rain, or you carry a different backpack brand where this cover won’t fit.
