Mil-Tec 3D Hollowfiber sleeping bag

This is a surprisingly high-quality three-season bag, complete with a compression sack. A word of warning: if you are big, you will have a hard time fitting inside!

The Thing with this bag is the construction and the materials: very simple & durable all around, with 3D Hollowfiber filling (two layers), polyamide outer fabric, and polycotton lining. The layered Hollowfiber stuffing simply means better insulation for a reduced thickness.

Other things include a drawcord tightening at the hood and inside on chest level to further increase the insulation. There's also a small pocket inside for all kinds of tiny stuff you might want to keep with you. Outside on the foot end are two loops for hanging the bag.

Measuremets 230 x 70 x 55 cm / (90.5" x 27.5" x 21.5"), compressed about 40 x 25 cm / 15.5" x 10". Weight about 2.05 kg / 4.5 lbs. The 70 cm / 27.5" shoulder width means that you have to be size Small to Medium if you're planning on closing the bag too! Even still this isn't the roomiest model available.

Unfortunately no data on min/max temperatures, but our tests showed this still works up to a few degrees below zero, further down if you know what you're doing.

Wash at 40 degrees Celsius (104 F), air dry only (hang dry). We suggest washing only when it's absolutely necessary, as every wash does harm to the insulation properties. Use a liner bag instead and wash it when it gets covered in sweat and other bodily fluids.

Staff comments

Considering the price, the quality of this sleeping bag seems amazing. We're talking simple, robust construction with a very efficient 3D Hollowfiber filling, a combination that produces a light and remarkably warm sleeping bag. During field testing, we concluded that in -10 ºC a grown man will get some sleep wearing only a pair of boxers, although things did get a bit chilly in the early morning hours. With some proper thermal wear I feel fairly confident in saying you'd be fine in -20 ºC. For comparison, the FDF sleeping bag, which is considered by many to be a brilliant winter bag, was found to be slightly less warm.

To sum it up: cheap, simple, effective and robust. I'd probably pay some 150 € quite happily for a bag like this in a sports store.
