Great winter bag>
Reviewed By ADRIAN, 03 Dec 2012

Just tried this bag out in the lakes in -5 and it kept me pretty damn warm! Not toasty toasty warm but enough for the temperatures not to be a problem! I did pair it up with a mountain equipment 3.8 helium mat. And it was as light as a (down) feather to carry. All in all this is an excellent bag, that ticks all the boxes.



Fantastic Down bag for 6 footers
Reviewed By Andrew, 06 May 2012

Spent a lot of time researching down bags with Pertex / DWR outers to protect the down from damp.
Decided on the RAB in the end as I could try before I buy in my local very helpful stores (Chichester & Hedge End).

The bag length is 220cm, and I am 196cm tall. The RAB point of Sale indicates bag is suitable for a person max length of 188cm, so I was worried bag would be too short.

However I can fit below the shoulder baffle quite comfortably, so this bag works for me.

Lovely warm soft deluxe feel inside the bag, as if I am home in bed, not outside in the cold damp on some distant hill in the middle of no where (Lake District April 2012)

Also fairly light and packs doen into a very compact size. Worked very well with the Mountain Equipment Helium 3.8 self inflating mat I bought too, on special offer.
