Giving you better sleep outdoors since 2019

Blue Bolt Solo Quilt offers tested and proven improved cold and wet weather sleeping bag performance for better sleep outdoors. 

It is made with:

  • a weather-proof, seam-sealed, bivy-like outer shell,
  • a vapor barrier liner (vbl) and
  • the innovative Climashield®APEX insulation.

Using these materials, the insulation is protected from moisture and windchill, and your quilt maintains its thermal performance – keeping you warm and comfortable wherever you are, whatever the weather.

The quilt comes with:


  • For quilts (and also sleeping bags) to perform to their temperature rating, an appropriately-rated sleeping pad is necessary. The pad works to insulate you from the cold ground and preventing conductive heat loss.
  • Store your quilt uncompressed to preserve its loft. Hang the quilt up in a dry place where it can air out before returning it to its storage sack – clean and ready for your next adventure.

The Blue Bolt Solo Quilt is your reliable “sleeping partner” for those multi-day excursions in multi-range of temperatures and weather.

How do you get reliable warmth?

The quilt design and materials work together to prevent convective, radiative, and evaporative heat loss.

  • Insulation loft is protected from outer and inner moisture 🡆 dry insulation = loft = warmth.
  • Extra warmth without the added weight by using vapor barrier technology.
  • Integrated hood keeps your head warm and protected from heat loss.
  • Unique non sewn through design guarantees zero cold spots and bivy-like protection.

Comfort is the 2nd half of the equation for getting you that good night’s sleep essential for the next day activities.

With Blue Bolt quilts, you have the freedom to adjust your coverage as needed – ventilate on warmer nights or bundle up to stay warm when the temperature drops.

  • Draft stopper protects you from incoming cold drafts.
  • Pad attachment keeps you, your quilt and your sleeping pad together.
  • Improved hood design that works in any sleeping position.

Thermally efficient design without sacrificing comfort – restless sleepers rejoice!

  • Roomy girth space allows you to move and adjust your sleeping position freely.
  • Ample footbox space allows your tired feet to relax in a normal position.
  • Soft liner fabric is comfortable to snuggle into.

Why use Climashield® APEX synthetic insulation?

Because it is the lightest weight and most thermally efficient continuous filament insulation on the market today.

  • Maintains reliable warmth even in wet and humid conditions
  • Dries up quickly when it gets damp
  • Continuous filament and even distribution means no quilting required, no cold spots, no clumping, no shifting.
  • Resilient under harsh conditions, holding its original shape after multiple uses or washing

Why use vapor barrier technology in the quilt liner?

Because it keeps your insulation dry and able to perform at its highest thermal efficiency in most challenging weather conditions.

How does vapor barrier liner work?

Vapor barrier liner (vbl) blocks both insensible (sweat that evaporates before it is perceived as moisture on the skin) and sensible sweat from getting in the insulation where it can condense and dampen it.

Added benefits to using vapor barrier liner:

  • Adds 5 to 10℉ to the base temperature rating by minimizing heat loss that happens through evaporation and minimizing convection heat loss through the fabric weave.

  • Makes you more aware of your rate of perspiration thus helping you to thermoregulate better, avoiding unconscious overheating and profuse sweating which can cause dehydration the next day.

Additional customization options available:

  • Breathable liner (instead of vapor barrier liner)

  • Extra-wide quilts to fit 2 persons (pricing will vary from published Solo Quilt prices).
The new Blue Bolt Solo Quilt features a new color combo and several improvements – building on our comfort-rated UL custom solo quilts we have been making for thru-hikers, mountaineers and alpinists since 2019.

We worked with our fabric supplier to develop new 10D ripstop nylon bivy shell and vapor barrier liner fabrics with softer hand-feel for the most comfortable sleep.

Real Teal outer shell / Robin Egg Blue liner. We carefully chose this beautiful nature-inspired color combo for its soothing vibe.

Unlike buckles and regular toggles-based pad attachment system, our system minimizes bulky hardware between your back and the pad, for a non-obtrusive sleeping experience.

We made it better with stronger felled seams, a more compact size, easier to use no-strap compression system.

The Solo Quilt v4.0 features a DWR-coated outer shell with just one seam. It means that it is highly water-resistant already. With the seam sealing feature, your quilt now has the ultimate water resistance. Recommended for camping in snow or camping under a tarp.

Do note, however, that this quilt is not rated waterproof for direct exposure to heavy rains.
