Looking for a new sleeping bag for a bit of bikepacking/touring, needs to be small pack size as needs to go on the bars and not silly expensive !
ideas please

Depends on how cold/warm you sleep and what temperatures you expect to encounter.

Define expensive as well as what scotroutes asks.

It will be in the next few months and price wise I’d say no more than £75

And use the code 10BLACKS at checkout

Are you bigger than 6ft or bigger chest than 46″. If so you may need a long bag and some makes may be too narrow.

Assuming average size – for light and compact you need down.

What about 330g good for +8C. Probably colder if you wear a bit of clothing inside. £211
