Part of Marmot's ultralight range of sleeping bags, the Helium offers a superb balance of quality, low weight, packability, and performance versus cost. It's comparable to many more expensive products, as it is lighter and more compressible than almost all of its competitors.

The Marmot Helium uses 800+ fill power down protected with Marmot's Down Defender to help the down to stay dry longer, loft better when damp and dry more quickly than untreated down. The Pertex Microlight fabric offers a combination of lightweight and good durability plus it's DWR coating will offer some water resistance. The fabric feels really soft which allows the down to loft freely and the slightly brushed feel of the Microlight lining fabric is extremely comfortable against your skin.

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

Faster tracked shipping options can be purchased at the checkout - see the drop down menu on the checkout page for options. If you require a faster delivery than we are offering please contact us at info@worldbackpacker.co.uk as we may be able to help.
