Nano Bag Custom Page - Multi week leadtime

Next Order Window: August 2026

Formerly Z-Strugi

This is the stupid light version of the zipperless/hoodless Sastrugi sleeping bag - which already is a niche product.

Still just a plain bag, generous sizing, quality materials. But now with down fill to match a 45°F comfort rating.

Sewn with box baffles like the big Strugi, but here they are not tall! The average fill volume of 7 ounces produce a loft of almost one inch on a good day.

12-13 ounces total for the regular size in 7d

Works well with the hooded Alfabatik Overbag

Left: 10d Forest Green / Black combo in 74"L - 59" - 40" circumference weighing 388g

Right: 7d Moroccan Blue / Olive combo in the same 74"L - 59" - 40" circumference weighing 362g

Dual color selection
