Cloud 800 F Wmns 20 Deg Reg

Product Overview

This women’s-specific version of the Cloud 800F is built for three-season backpacking, offering higher performance insulation in a design focused on comfort and freedom of movement. It uses 800-fill (FP) DriDown® insulation, a zipperless “comforter” style wrap design, and thoughtful features to make sleeping outdoors more like sleeping at home.

Key Features & Benefits

• Zipperless comforter-style design: Instead of a full side zip, the bag uses an oversized integrated comforter flap that wraps around you, allowing more freedom of movement. Surface2Air Sports+2TGO Magazine+2

• 800-fill DriDown® insulation: High loft, responsibly sourced down treated for moisture resistance helps maintain insulation even if conditions are damp. TGO Magazine+1

• Material & construction: Shell and liner use 15d nylon ripstop fabric. gearx.com+1

• Sleeping pad sleeve: Keeps your sleeping pad in place beneath you, replacing the need for heavy bottom insulation and helping maintain comfort and warmth from beneath. The Outbound+1

• Self-sealing foot vent: You can pop your feet out (or vent the bag) when you get too warm. Great for side sleepers or for flexible temperature control. Surface2Air Sports+1

• Insulated shoulder “pocket”: Helps the comforter wrap better around you and reduce drafts at the shoulders. Surface2Air Sports

Best Use & Ideal For

• Backpackers and campers (especially women) looking for a premium 3-season down bag that doesn’t feel like a traditional mummy bag, and gives more space and freedom of movement.

• Side-sleepers or people who toss and turn — the wider comforter style and pad sleeve design help maintain comfort.

• Trips where pack weight matters but so does comfort: the bag strikes a balance between performance and livability.

• Conditions where nighttime temps drop into the teens or low single digits Fahrenheit (or a few degrees below zero Celsius) — given the ratings, it handles colder nights with good gear underneath.

Considerations & Trade-Offs

• The comforter-style, zipperless design may feel different if you’re used to a snug mummy bag — some reviewers note movement can cause gaps or drafts. TGO Magazine+1

• Because the bottom insulation is minimized (thanks to the pad sleeve design), the quality and warmth of your sleeping pad matters a lot — a sub-par pad may reduce overall comfort/warmth. The Outbound

• While the weight is quite good for the performance, if you’re ultra-light backpacking you might find lighter/less roomy bags.

• As with all down bags, keeping it dry and well-aired is important for insulation performance and longevity.

Summary

If you’re looking for a sleeping bag that delivers high-quality down insulation, comfort-oriented design, and a women’s-specific fit, the Sierra Designs Cloud 800F Wmns 20 Deg Reg is a standout. It gives you flexibility (zipperless design), practical features (pad sleeve, venting footbox), and strong materials (800FP DriDown, 15d nylon) for three-season use. Just make sure your sleep system (pad + layers + tent) matches the conditions you’ll face.
