Description

TheMajolica Blue Helium 400 is a sleeping bag from the brand Mountain Equipment.

With its 700 CUIN natural down filling and a comfortable temperature of -5 °C, this sleeping bag will keep you nice and warm on your treks, hikes and campervan trips from March to October. The outer material Helium 20D is insulating, lightweight and Ultra-compressible, ensuring you get a high-performance down jacket that meets your expectations. The snug yet comfortable technical Alpine 2.0 Fit fit will ensure you sleep soundly whilst optimizing heat retention.

The construction of the filling is optimized to ensure an even distribution of down, providing consistent warmth. The hood and the footbox are designed to provide you with warmth and comfort. Inside the bag, a 100% recycled Supersoft 20D fabric with a PFC-free DWR water-repellent treatment will keep you warm and protect you from the outer elements. The magnetic fastening Lode Lock™ and the drawstrings at the collar, which are easy to use in the dark, allow you to adjust the warmth to suit your needs. This sleeping bag comes with a waterproof storage bag and a compression sack.

This lightweight, high-performance and comfortable sleeping bag will ensure you get a good night’s sleep on your treks from spring to autumn!
