The highest performing fully featured zipper-less quilt we have made yet: The Strugi-Q

Comfort rated based on real life feedback and over 25 years of down making experience

Underside opening with parallel sides making draft control more or less built in. This is possible by sewing the quilt body into a mummy shape instead of attempting to wrap a two dimensional blanket type around the user

Two overall shape options: No inward taper until hip level or adapted mummy contours. See diagram on menu below

Horizontal baffles. With our ‘dense pack’* approach the down stays put for longer and a continuous baffle run allow underside down to be moved up and around. *eschewing theoretical values and calculated percentages we instead use feel and real life experience. The fill amount for a given chamber is high to point where the down doesn’t ‘fully’ loft – this buffer is what you want out there for sure

As always a permanently closed foot box with a round end piece for superior warmth; no zipper, drawcords or socks stuffed in leaky holes. 40″ is good up to size 12 for mostly side sleepers. Back sleepers need to size up to 44 around size 11 feet

Width is the most important spec to get right. The Strugi-Q makes this easier with six real life options: 50″ – 53” – 56” – 59” – 62” and the big guy: 68”. Most will be happy with the 56″ width. Skinny folks, expert users and weigh weenies can go narrower. The restless, the big, and the dog co-sleepers can size up

The 70″ length is fine up to 5’11”. Snugglers and ear warmers can go up a level if in doubt

Also with differential cut, ETC, neck draft collar, straps and 10d materials

Sastrugi zipper-less bag vs Strugi Quilt:

Comparing the two shows that weight savings are minimal. A person needing the 59″ wide Sastrugi bag would choose the 56″ or 53″ Strugi Quilt, but the added hardware of the quilt (ETC, straps, snaps and buckles) almost make up for the difference.

In environments with consistent night time temperatures, say western mountains at altitude with nearly guaranteed cool nights, the Sastrugi makes sense: draft free, easy to use, simple, affordable.

On the other hand anyone gearing up for a streak of major thru hikes should consider a quilt. Thousands of miles and hundreds of days along changing seasons and environments require the adaptability of a modern well designed quilt.
