Pajak CORE 350 Regular - Navy
See our entire range from Pajak here!
The Pajak CORE 350 Regular is the perfect sleeping bag for those who want to travel light, sleep warm and trust their equipment to deliver – night after night. Whether you're hiking in the mountains, cycling through forest landscapes or sleeping under a tarp by the water, the CORE 350 is a comfortable, reliable and extremely packable companion.
With a comfort temperature of around +5 °C and a limit of –1 °C , the sleeping bag is adapted for warm months, but at the same time offers a safe margin for chilly spring and autumn nights.
The CORE 350 is filled with 300–350 g of Polish RDS‑certified duck down , with a fill power of 700 CUIN . The down is:
very warm in relation to weight
sustainable and long-lasting
quickly expanding after unpacking
The down is distributed in Z-shaped baffles , which prevents the filling from shifting and creating cold spots. You get even warmth all over your body – even after many seasons of packing and unpacking.
The outer fabric is made of Toray Airtastic SLF15 , an extremely lightweight yet durable ripstop material. Combined with Pajak's moisture management system HMS, you get a sleeping bag that:
resists moisture and condensation
ventilates moisture from the inside
feels dry and comfortable even during humid nights
The fabric is also DWR-treated for increased protection against external moisture.
Areas around the head and feet are reinforced because this is where condensation and friction occur the most.
CORE 350 Regular weighs only about 685 grams and can be compressed to a pack volume of around 5 liters .
This means:
lighter packing
more space in the backpack
faster and smoother trips
Perfect for ultralight adventurers, backpackers and multi-sporters.
Pajak has optimized the design to work smoothly even in the dark and with cold hands:
One-hand adjustable hood
3D collar keeps you warm around your shoulders
YKK zipper that runs smoothly and doesn't get stuck
Internal heating pipe that prevents cold air from seeping in
Internal pocket for headlamp, phone or valuables
Drying loops to hang up the sleeping bag in the morning
You also get two bags:
✔ a compression sack for the trip
✔ a mesh bag for proper long-term storage of the down
