Pajak CORE 350 Regular - Navy

The Core 350 is a sleeping bag made for the warmer months. Take it with you for a night in the forest, a hike in the Tatra Mountains or a bivouac under a tarpaulin by the river.

With a comfort temperature of around +5°C, it is perfect from spring to early autumn. The -1°C limit gives you a safety margin for those unexpectedly chilly nights, especially higher up in the mountains.

The Core 350 is filled with 300 grams of Polish duck down with a fill power of 700 CUIN. Pajak has been using this material for years and trusts it completely – it is light, durable and built to last.

Once you are out of the bag, the down quickly regains its airiness and forms a soft, warm layer around you.

Thanks to this, the sleeping bag keeps you pleasantly warm all night long – no matter how you sleep.

Pajak only uses RDS-certified down, which means it is ethically sourced and with full respect for animal welfare.

The filling is placed in Z-shaped baffles that stabilize the down and prevent cold spots from forming – no matter how many times you have packed or unpacked your sleeping bag.

Weighing just 650 grams and with a volume of up to 5 liters, the Core 350 always fits – whether you are going on a multi-day hike, a minimalist bike ride or a weekend in the forest.

It doesn't weigh you down, it doesn't take up half your backpack and it keeps you warm when the night gets colder than expected.

The outer shell is made of ultra-light Toray Airtastic SLF15 – thin yet exceptionally durable and hard-wearing.

The DWR coating protects against external moisture, while the fabric itself allows steam to escape from the inside of the bag. It's supported by Pajak's HMS (Humidity Management System), designed to keep the inside dry and comfortable.

Pajak has reinforced the fabric around the head and feet - the areas most exposed to condensation or contact with the tent's flysheet.

These details are most important in the warmer months, when warm days turn into cool, damp nights.

When you're camping, everything should work easily and intuitively - especially after a long day on the move.

That's why the Core 350 can be adjusted with one hand, even in the dark or with gloves on.

The 3D collar locks in heat where it escapes the fastest - around the shoulders. The YKK zipper runs smoothly and the draft tube prevents cold air from seeping in.

Inside there's a pocket for your headlamp, phone or documents - so you don't have to fumble around in your backpack in the dark. Outside we've added drying loops to hang your sleeping bag over a branch or the tent after the night.

The set includes two storage bags – a compression bag to pack in your backpack and a mesh bag to store between trips.

The second is just as important as the bag itself. Down needs space to rest and maintain its airiness. Thanks to this, it stays warm and effective – both on the first and the hundredth night out in the field.
