What's #1 cause of a wet sleeping bag? Condensation.

Waking up in a damp sleeping bag is a terrible feeling I am personally familiar with. It has a terrible impact on your entire camping experience, and in some cases might get you cold or sick.

I designed these 2-person and solo ultralight quilts with built in vapor barrier to solve the sleeping bag condensation problem in bad weather without feeling clammy. This ultralight, no-fuss sleeping solution keeps me and my partner dry, warm and comfortable in the Himalayas.

Field tested 3000kms / 120 passes in the High Himalayas

I completed a 4 month exploration / alpine style / minimalist / ultra hike across 120 passes in Uttarakhand, Himachal, Ladakh (Indian Himalayas) and had a very positive experience in using the Bluebolt solo quilt.

It's is super light and comfortable even while sleeping at near zero temperatures. I did not carry a tent and was mostly sleeping in the open with just the quilt and basic Decathlon Quecha sleeping mat. I only used a lightweight bivy in case of rains and cold winds in which the quilt again was providing comfort and warmth from 1000 to 5000 meters altitude.

The quilt never had any condensation and easily dries when wet. When sleeping in the open it nicely cuts the cold wind. One of the best items in my minimalist gear set this year!

Design and materials both matter.

No loft = No warmth

Do you know that the sleeping bag compressed under you gives zero insulation, and, thus, zero warmth? 

We cut off this useless back side of the bag to make it lighter and take less space in your pack.

Sleep whichever way you want

You don't have to sleep like a MUMMY.

For you to experience full freedom of movement without restrictions and cold drafts, we designed a quilt with wide girth and draft-stopper.

High Performance

Innovative features other quilts don't have.

With extra length to keep your head warm, anatomical shape that cocoons your body and 3D sewn foot box for maximum warmth.

What's better than down?

Condensation is the death of down sleeping gear.

USA Military choose Climashield for superior insulating and quick drying performance in wet condition compared to goose down. So did we.

Bivy-level protection built in

10D ripstop shell that is durable, windproof and incredibly water-resistant.

You'll now be sleeping in the open under clear skies or under a shelter during a storm without getting your bag wet or feeling the windchill.

Vapor barrier technology

VB inner with breathable draft stopper to prevent clammy feeling.

Hike safely in the wet, humid and cold conditions found in places such as Alaska, PNW, Scandinavia, and the Himalayas.

Anatomy of the QUILTS

High performance features

✔ Draft stoppers - a simple and effective system to stop cold drafts without pad attachment.

Tried and tested in South Pole, Alaska, Greenland and Aconcagua by Ray Jardine, pioneer of lightweight backpacking. 

✔ Climashield® Apex  - Best-in-class synthetic insulation that outperforms down in wet conditions.

Choice of USA military and world's best brands for their high performance outdoor gear.

✔ Anatomical shaped-cut - Designed to cocoon the full body in a way that maximizes warmth and reduces drafts.

Our quilts cover and insulate the head, the most critical part of the body.

✔ Vapor-barrier inner -  This solves the wet sleeping bag problem by preventing condensation inside the quilt. Minimizes conductive, convective and evaporation heat loss.

There is no clammy feeling as the moisture vents out through the breathable draft stoppers. 

✔ Windproof DWR shell - Bivy-level protection built in a quilt.

Now sleep in the open or under a tarp without wind chill.

✔ Rectangular foot-box - A sewn 3D foot-box that offers maximum warmth and comfort.

Use the foot-box to keep your water bottle or camera warm in the night.
