Key features
Small & light enough to carry on longer trips
Hydrophobic fill keeps you warm even if damp
Warm, comfortable and very lightweight, the OEX Helios EV Hydrodown 300 Sleeping Bag is ideal for temperatures around 3°C, but will keep you comfortable down to -3°C.
The 300gsm / 600 Fill power duck down insulation has a hydrophobic coating that makes it practical for British camping - it retains its loft in damp conditions, so it still keeps you warm.
The compression stuff sack lets you pack it down to a very compact and manageable size for packing and carrying (it also comes with a larger mesh bag for long-term storage).
Ultra comfort lining - Inner pocket
- Internal wind baffles
- Anti-snag zipper band

Good bag
I've got 2 of these had them on multiple trips over the years. With my son .
Never been cold yet. Yes these are a summer bag and yes they do lose feathers .but at around 750g very light and compact.

Going down fast
Down everywhere, but not in the bag. In a few weeks there will be none left in the bag..do Go Outdoors do refills..Very expensive for the lack of quality..

Best 3 season down bag
This is a great 3 season bag, especially when compared to similar models from Rab and Nordisk which are 3 times the price. it's comfort is closer to 6 degrees so get a Leviathan if you feel the cold.

Poor quality
Dont bother. Used twice and stitching has come apart substantionally resulting in the filling coming out. Also the quality of the down is cheap with little loft.

barely adequate filling. If...
barely adequate filling. If held to the light you can see very little down, I will use this as a summer sleeping bag but it certainly is nowhere near the advertised 3 season. Disappointing.
Zips and other features are well made and look durable.

Feathers everywhere!
I found this loosing feathers everytime I slept in it. It's nowhere near as warm as I expected and likely to get less so as the filling escapes! Avoid.

NOt very warm
Used a couple of times in late spring and I constantly woke through the night very cold.
In the morning my tent was full of feathers, not down, like I’d been wrestling a goose.
Not recommended

WORSE SLEEPING BAG EVER!!
I agree with previous poster here. There were numerous negative reviews previously, before GO updated website.
This sleeping bag is in no way what so ever a 3 season bag.
It is a terrible bag. AVOID

Not very warm. Add min 5C to quoted ratings.
Bought 18 months ago when there were lots of good reviews. Recent reviews were bad so now they’ve removed them all! Used by several people and it’s nowhere near the ratings. 2 season use only.

Very lightweight and compact BUT this is not a 3 season bag and shouldn't be sold as one!
