A lightweight and compact 3-4 season synthetic sleeping bag, with Du Pont Thermolite™ fill.

OEX's Fathom EV is not only their first 3-4 season sleeping bag, but also their most compact, combining comfortable and durable fabrics with superb insulation.

The double layered 140gsm Thermolite insulation is ideal for temperatures which are just below freezing, but will still offer you a comfortable nights sleep when it drops as low as -23oC.

Designed to be tough and durable, without compromising on warmth or comfort, they have used a water-resistant ripstop outer fabric which will be certain to appeal to all those who prefer to wild camp under the stars.

An internal zip baffle and drawcord collar help to prevent any draughts, while the adjustable the 2-way zipper is great when
you overheat and feel the need to ventilate.

It compresses down nice and compact into its own stuff sack and, once inside the waterproof carry bag (also included), you'll find that it attaches easily to the OEX Vallo range of rucksacks for hasssle free carrying.

Good bag, 10 October 2016
By Kent (Belfast)
Compression bag is very sturdy and compresses the bag down to a very good size. The dry bag is well sized so I can get a blanket in as well. I used the bag inside a bivvy under a tarp in about 3 degrees Celsius and found it both warm and comfortable. I didn't need to use the hood and did need to unzip during the night to cool down a bit.
The zip is fantastic, the loop means it can be closed with one finger. The zipper moves smoothly without snagging. Very good value.

Warm, 04 July 2016
By Molemaster (Northamptonshire)
I bought this bag for my daughter, an avid kayaker, who regularly camps out in all weathers and all seasons in some pretty damp places.

With frost on the ground outside, she was very comfortable without having to layer up. Above about 10C, she finds it too warm.

I agree with Pete that this isn't the most generously-sized bag, but at this price, it represents excellent value.

April Warmth, 25 April 2016
By Pete (Worcester)
I bought the OEX Fathom EV and used it the same day on a tame April night. Knowing that it's rated 3-4 Seasons I had expectations of being warm, if not over heating, and this bag delivered. Waking in the night I realised I was too warm and changed tactic, removing clothes and opening the bag - simply to prevent sweating.

The pack size/weight in the compression sac is quite reasonable. Even found a nice surprise in there of a dry bag (yet, unconfirmed whether it keeps contents dry), big enough to contain the compression sac.

One thing to be aware of in terms of fit; I am 6'1'' (185cm), 15ish stone (~100kg). I can get to close the zip and velcro, but within the bag itself there is little room for manoeuvre. Any bigger than me and you will struggle.

I'm really pleased with this purchase, I'd be happy to recommend - especially for Scouting / D of E. Just be aware of the sizing!
