Why did I buy this sleeping bag?

The adventurer in me decided that it would be a great idea to take myself further out of my comfort zone and book a trek in Morocco involving the climb of Jebel Toubkal and number of days spent in basic mountain refuges. Despite a reputation for being a hot country the Atlas Mountains of Morocco can get very cold at night and snow is not uncommon in September.

Therefore I needed a four season sleeping bag that can comfortably deal with temperatures below freezing. The travel company recommended I take a 3/4 season sleeping bag for the time of year. Therefore I thought it best to be covered in case of cooler nights. I wanted a winter sleeping bag therefore that I could potentially also use for camping.

Practicality of the Bionnassay -5 Four Season Sleeping Bag

As a four season synthetic bag sadly the Bionnassay is relatively heavy at 1.9 kg in it's large size. Therefore it's a little on the heavy and bulky side as a lightweight backpacking bag. However for use as a trekking bag where you have access to mules or very short walking distances. Therefore this bag is best suited for trekking and camping use.

So what's it like to sleep in?

So far I've tested this bag in temperatures down to 0 degrees celsius and have found that I remain toasty warm. In fact I was almost too warm! The lining feels soft and luxurious

At temperatures above 10 degrees celsius I found that the bag was far too warm and I became damp and clammy.

I would therefore recommend you use this bag for camping around the 0 degrees celsius and below mark.

Would I buy it again if I had the choice?

Definitely!

If you want a value for money warm sleeping bag from a highly repuatable company I would recommend this bag. As Quechua products have a two year warranty there is peace of mind that this is a good quality product

My next planned trip is hopefully going to be to the Himalaya's and therefore I will definitely be taking this sleeping bag with me.
