Everything you need to know about your CapiSpexi sleeping bag






I used this for a weekend hiking trip in the mountains. It weighed next to nothing in my backpack and compressed down incredibly small! The inner material was so soft and pleasant to sleep in.

My partner and I bought a left zipper and right zipper bag and spliced them together. It works perfectly! No cold drafts in the middle and plenty of room to stretch. Absolutely brilliant purchase.

Very durable nylon outer shell. We camped in high moisture conditions and I woke up dry and comfortable. Washing it in the machine was very easy too, with no clumping. 5 stars!
