Ultralight down sleeping bag for spring, summer and early autumn - perfect for users up to 165 cm tall

The Pajak CORE 350 Short is the lightest and most packable sleeping bag in the CORE range – created for adventurers who want to keep weight down without compromising on warmth or comfort. It’s ideal for warmer months and equally perfect for mountain hikes, cycling adventures, forest nights or bivouacs under a tarp by the river.

With a comfort temperature of around +5°C and a limit of –1°C, it is safe even on unexpectedly chilly nights, especially in high altitude terrain. The short model is optimized for users up to 165 cm , which means you avoid unnecessary dead space and retain heat more effectively.

Premium down – light, warm and reliable

The CORE 350 Short is filled with 300g of RDS-certified Polish white duck down with a fill power of 700 CUIN . The down expands immediately after unpacking, creating a warm, airy layer of insulation that keeps you comfortably warm even when the temperature drops.

The down is located in Z-shaped baffles , which:

keeps the down in place

prevents cold zones

maintains performance after many seasons

provides even and stable heat around the entire body

Ultralight and durable – built for adventure

The outer fabric is made of Toray Airtastic SLF15 , an extremely lightweight yet robust material. Combined with GELANOTS Ultra Light Ripstop, you get a shell that:

resistant to wear and tear

feels soft and supple

breathes well

keeps moisture away thanks to DWR treatment

With Pajak's Humidity Management System (HMS), moisture is transported away from the inside, which prevents the sleeping bag from becoming clammy or damp during the night - a common problem during hot days and cool, damp nights.

Pajak has also reinforced the zones that are often exposed to moisture and condensation: the head end and the foot end .

Designed for simplicity and comfort

After a long day, you want your equipment to just work. That's why the CORE 350 is designed to be intuitive and easy to use, even in the dark:

One-hand adjustable hood

3D collar keeps you warm around your shoulders

Smooth-running YKK zipper

Internal draft tube that stops cold air from seeping in

Internal pocket for headlamp, phone or valuables

External drying loops for quick airing in the morning

Low weight & minimal packing volume

The CORE 350 Short is extremely packable:

Weight: approx. 660 g

Pack volume: down to 5 liters

This means you will always have room for your sleeping bag, whether you are traveling light, cycling long distances or backpacking for several days.

Two bags included

You get both:

✔ Compression bag – to minimize the pack size in the backpack

✔ Ventilated mesh bag – for long-term storage (down needs space to retain loft)
