in the Himalayas

Field tested over 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 Blue Bolt 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!

The thinking behind the Blue Bolt quilts

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

😴 Back sleepers, stomach sleepers and side sleepers — rejoice! You don't have to sleep like a MUMMY anymore.

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

Cold Weather Performance

💡 Innovative features that conventional 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.

Wait, there's more... design and materials both matter

What's better than down?

👍 Superior synthetic insulation that's cruelty-free.

☑️ Climashield® insulation innovation offer superior insulating and quick drying performance in wet condition compared to goose or duck down. No animals harmed to keep you warm.

Bivy-level protection built in

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

☑️ Fancy sleeping in the open under the clear skies? You can without worrying about getting your bag wet or feeling the windchill. (For stormy weather, you should still sleep under a shelter 🏕️😉 though.)

Vapor barrier technology

😴 10D VB inner with breathable draft stopper to prevent that clammy feeling.

☑️ Hike in the wet, humid and freezing cold conditions found in places such as Alaska, the PNW, Scandinavia, and the Himalayas, and be confident that you'll get a good night sleep.

★★★★★ An ultralight alternative that rocks!

The quilt is a perfect companion for my solo treks. I used it for 10 days during my trek in Laddakh and camped at altitudes ranging from 4000 meters to 4750 meters. The quilt is ultralight (weighs 650 grams), extremely comfortable as compared to sleeping bags and can withstand temperatures of -5 degrees easily. It kept me comfortable even while camping at 4750 meters with a basic mat below my back.
