Nano Bag – Multi week lead time – Next Order window late December 2026
$335.00
Zipperless bag. Simple, light, no nonsense
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 45°F or 35°°F comfort ratings.
Sewn with box baffles like the big Strugi, but here they are not tall! The average fill volume of 7 ounces (45°F) produces a loft of almost one inch on a good day.

Received this nano bag over the winter and spent this late spring-early fall testing it out in Montana. Obviously craftsmanship is top-notch. I had no problems over heating. I got this bag with intentions to extend the temp rating by wearing extra clothes. I tested it in just base layers and was completely comfortable at 40F. This fall it has taken me just below freezing on a handful of occasions with snow, in just alpha layers and a buff. Id imagine I could go lower with a puffy and better hat no problem. The 7d has held up fine with my St. Bernard in the tent. Ordered my wife the nano quilt this summer. Highly recommend! Very happy with it!
