Patizon D 290 - TRUE ULTRALIGHT

The D 290 is our ultralight sleeping bag with an outstanding balance of thermal comfort, weight, and packability — all while retaining every technical detail. It has exactly the size and weight that won’t get in your way, yet it provides the warmth you need for any summer adventure. More experienced and cold-resistant users can comfortably use it from May to September. And in winter, it’s a great choice for mountain huts and winter rooms. We’ve also equipped the D 290 with a straight front zipper, which not only improves the thermal performance of the sleeping bag, but also makes the zipper easier to handle and reduces the packed volume.

• We use high-quality European duck down with RDS certificate.

• Ergonomically shaped foot box providing the best comfort for your feet.


• Streight semi-automatic SHZ zipper with two sliders and unique way of operation. Ending at the height of ankles.


• The zipper is 3mm thin instead of widely used 6mm. This means better insulation and weight savings.


• Precisely shaped insulation baffle around shoulders/neck preventing the heat loss. Due to specific construction, there os no need for using buckles or velcroes.

• Compression bag compresses the sleeping bag 13 times the volume. It is delivered with every sleeping bag.

• Ergonomically shaped hood allows head movement.


• Insulated baffle around the hood is filled with CLO Vivo Endurance insulation. It works better with the moisture you breath out and it adds extra comfort around the drawcord.


• Sewn points for hanging the sleeping bag when in storage or when drying.


• Slightly wider mummy shape of the sleeping bag copies the shape of your body to prevent heat loss, but still allows you to reach your feet even when fully closed (to put dry socks on, for example).


• “Z” construction of the boxes for the ideal distribution of the down.


• The zipper on the left or right side


• The down distribution ratio is 50:50 (bottom : top)

Patizon D 290: technical details

Anatomically shaped hood

The hood is a crucial pat of a sleeping bag. We believe that even a light sleeping bag needs well shaped hood that prevents heat loss at all costs, because your head is a part of body that looses heat very quickly. The hood adjustment is made with a draw cord and can be tightened by one hand.

Anatomically shaped sleeping bag. Especially the foot box.

The shape of Patizon sleeping bags follows the shape of a human body. This is the way to preent cold spots that need heating. Furthermore, we have designed the shape in a way that allows for some more movement inside - in case you want to stay insede the sleeping bag and change your wet socks for the dry ones. In Patizon it is possible. The footbox is made with several chambers and is precisely insulated. Your feet can get cold easily adn we don't want that to happen.

Insulation baffles right where you need them.

The main zipper is backed with down-filled insulation baffle to prevent any heat loss through the zipper. Thanks to the construction with straight zipper the baffle works extremely well. Around the shouklders, there is another insulation baffle that can be tightened with a draw cord and si constructed to work perfectly without any velcros. 

The semi-automatic zipper. Smarter than you think.

Patizon sleeping bags utilise premium SHZ zippers. Moreover, we use semi-automatic pullers, that have two modes. When in mode STOP (picture 1), the puller stays in place no mater what and you can not open it by accident. In Go mode (picture 2) you can easily open the zipper just by tearing the sides apart from each other. It is as easy as it sounds. This functionality makes any velcroes or other buckles to lock the zipper obsolete. 

And of course, for pleasant closing of your sleeping bag we have included an ergonomical puller.

Smart details. And something more.

Inner zipper pocket to keep your valuables or electronic devices warm is included. No surprise here. There is a bunch of textile loops on the bottom of Pation sleeping bags to hang it when storing or drying. But there is more. With every sleeping bag, you get a storage bag that keeps your puffy friend packed but still lofty, to give it the best longevity as possible. And of course there is a compress sack included and it can make the sleeping bag ultra-small to save space in you backpack.
