Big Agnes's Pluton UL is a great ultralight bag, the amount of down in it is high compared to the total weight of the bag and with a 4C recommended temperature range it compares very well with other bags in this category. It also has full length zip, shaped footbox and hood.

Description  Features
You've got ultralight adventuring down to a science, right? Your pack and 90% of its contents is totally dialed in for fast and light on-trail travel in warm temps, but one thing is weighing you down. Even in those warm summer months, as soon as you get up high or down low near water, that chilly quilt or bulky old bag you've been using since high school is not cutting it. The Pluton UL is a highly compressible sleeping bag with a cozy lining of incredibly lightweight and packable 850-fill DownTek™ insulation. It will keep you warm and keep your pack light, whether that's a backpack, bikepack or packraft. 
  • Crazylight minimalist mummy bag for your fast and light adventures
  • Highly compressible with water resistant 850 fill DownTek™
  • DownTek™ water-repellent down repels water while maintaining insulating value
  • Minimalist hood with drawcord
  • Low-profile cordlock lets you un-cinch the hood with one hand
  • Full-length zipper can be opened up for quilt use and provides easy temperature regulation
  • Anti-snag zipper for a smooth, quick zip
  • 70" / 178cm YKK #3 locking zipper
  • Ergonomic footbox construction provides more loft and warmth
  • Two-way zipper
  • Zipper Garage
  • Interior fabric loops for sleeping bag liners
  • Streamlined exterior loops for hang drying or storage#
  • Mesh storage sack & nylon rip-stop stuff sack

Big Agnes' Pluton UL 40 Down Sleeping Bag is a very light sleeping bag with a Big Agnes temperature rating of 4C, this is not an EN Tested rating but by comparing the amount of down and the quality of down in the bag we can verify that its a realistic figure roughly equivalent to the EN Comfort Limit.

At less than 500grams this bag is at the high performing end, perhaps not our lightest at this insulation level but its up there with the best, and the price point compares well.

It has everything you would want for this category of bag, virtually a full length zip with 2 way sliders, a shaped footbox and down filled hood. The hood lacks sophistication but that is probably what you would expect for this category of bag.

UK Orders

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 Tracked Services

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).

EU Orders

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 Services

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 info@worldbackpacker.co.uk as we may be able to help.

Rest of World Orders

We aim to ship all orders placed before 3pm the same day. The default shipping charge 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 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.

Faster Tracked Services
