  1. Maksym

    I have not had an opportunity to test the sleeping bag yet but the thoughtfulness of the design and construction quality breeds confidence. I am extremely pleased with the shipping speed. It took only a week to deliver it to the UK from Ukraine.

    I have tested this sleeping bag trekking down the Jordan Trail in dessert conditions of Wadi Rum for two weeks. Provides very comfortable sleep up to 0 degrees. At -2 I slept OK but had to put a fleece over base layer and tighten the hood so that very little of my face was exposed. It dries quick and weighs very little.
