The Mystic UL 15 is part of the classic down series of Big Agnes sleeping bags that offer warmth, compressibility and the Big Agnes System which integrates the sleeping bag and sleeping mat. Now even lighter.
Ultralight down fill Big Agnes System bags designed to excel in all conditions
The Mystic UL 15 is one of our most technically designed Big Agnes System bags, using our Flex Pad Sleeve design, a very durable nylon ripstop shell fabric, and super cozy 850 fill power DownTek™ water repellent insulation. This bag combines ultralight versatility with a long line of packable creature comforts. Whether you’re a 3/4 length-pad-carrying, fast fly tent-gram-counter or just gearing up for a trip where weight and packed size is important, this is the go-to bag for you.
Big Agnes's 2019 Mystic UL 15 Down Sleeping Bag is light enough to take backpacking and yet it is more focused on comfort than just the weight. The stretch fabric designed to contain the sleeping mat improves the connection between bag and mat making for a great nights sleep.
The Downtec hydrophobic treated 850 fill power down repels water and speeds up drying time it if does get wet. The lightweight nylon ripstop fabrics are durable and soft to the touch. Vertical side walls help to trap heat closer to your body and the tapered vaulted foot box creates wiggle room for your feet. The bag is well proportioned and quite spacious internally. This would suite people who want that extra space or those who move around a lot as this has the added benefit of the Free Range hood.
To use the full pad sleeve a rectangular sleeping mat is needed and the dimensions of the bag need to match. The material does stretch enough to fit a pillow in too to maximise that comfort.

We aim to ship all orders placed before 3pm Monday to Friday, on the same day. Free shipping is offered for UK Orders over £15 order value. The form of shipping will be at our discretion and will be at the most cost effective service. For most parcels this will be Royal Mail Second Class Post, the timescale for delivery is not guaranteed but Royal Mail aim to deliver second class post in 3-4 working days. Some parcels may require a signature.
Faster shipping options can be purchased at the checkout - see the drop down menu, First Class post is available, as is Next Working Day Delivery. We can arrange Next Day Delivery for a Saturday (when the order is placed on Friday) - call us for charges on an individual basis (01740 661467).
We aim to ship all orders placed before 3pm the same day. The default shipping is 'Standard Delivery'. This is an airmail service which does not offer tracking but is very reliable. We have learned from experience that transit times for non-UK orders can be very unpredictable. To geographically close countries in Europe the times are generally up to 4-5 days but can sometimes take a lot longer - we don't know why.
So, for EU Orders over £15 in value we offer FREE delivery, but the service time is unpredictable. If you need your order by a specific date you can opt for a faster service at the checkout.
Faster tracked shipping options can be purchased at the checkout - see the drop down menu on the checkout page for options. Typically the service we can offer is 2,3 or 4 working days, if you require a faster delivery than is showing on the drop down menu please contact us at email@example.com as we may be able to help.

To geographically close countries in the times are generally up to 4-5 days but can take a lot longer - we don't know why. Countries farther afield generally take longer but the spread of transit times is amazing, we have been notified of parcels arriving in Australia after 3 days and others taking a month and (rarely) longer than this.
So, while the shipping options for ROW are quite cheap the service time is unpredictable.
