Berghaus Transition 300C Sleeping Bag Review

I’ve owned the Berghaus Transition 300C sleeping bag for 7 months and have used it in late spring, summer and autumn 2023.

It’s a great bag but it’s not for everyone. At the lower end of the price range, something had to give and it certainly did.

This is my honest review.

  • Plenty of space, especially in the foot/leg area
  • Affordable
  • Toggles for tightening the hood and shoulder area
  • Can be fully opened and used as a cover
  • The outer is rip-resistant
  • Well built
  • Washable


  • Heavy at 1.93kg
  • Large and bulky (see photos below)
  • Inner material soaked up sweat/moisture and was slow to dry (polyester)
  • The stuff sack isn’t waterproof and on a rainy day, I had to put it in a plastic bag to keep it dry.

Size and Weight

This sleeping bag is 220cm long and 80cm wide – I found that this offered plenty of room around the foot and leg area. This is the opposite of a mummy sleeping bag and I appreciated the extra room as I hate my legs being restricted.

When packed away in the compression sack, this sleeping bag measures about 38cm long and 26cm wide – I found that this made it too big and bulky for backpacking, the sack took up way too much space in my rucksack.

It weighs 1.92kg which is heavy, considering that this is a summer sleeping bag. It weighs about 400g more than good quality 4-season sleeping bags that have more insulation.

In a nutshell: I found this sleeping bag great for wild camping where I didn’t have to walk too far and also on campsites but it’s too heavy and bulky for summer backpacking.

Here are the key features. I’ve used all of them during my testing:

1) It has two zips, one at the feet and one all the way down the left side.

2) It can be fully opened and used as a cover – I appreciated this feature on a really hot summer’s day in 2023.

3) There’s an internal pocket, which is great for securing important items if you’re in a shared hut etc.

4) It has two toggles for tightening the hood and the shoulder area of the bag separately. I found this handy as I could trap my body heat in the bag by tightening the toggles.

I’m 6ft2 and fit into this bag just fine. I could stretch my legs out with a couple of inches spare. 

I did find it a little tight around the chest area, but I was wearing a jumper and I’m overweight; I’m confident an average-sized user wouldn’t have any issues here.

There’s plenty of room in the leg area, so those who hate restrictive mummy sleeping bags will appreciate the roominess of the Transition 300C.


I’ve used this on the mountains in Snowdonia (UK) when the temperature went down to 3°c, and I had no issues with the cold. I would be comfortable in this bag down to 0°c but no lower than this.

Where This Sleeping Bag Could Be Improved

Given the very reasonable price of the Berghaus Transition 300C sleeping bag (I paid £50), I wasn’t expecting all the bells and whistles but here are a few things that more expensive bags have that this one doesn’t:

  • Lighter weight
  • Waterproof stuff sack would be better
  • Proper down fill rather than polyester would be better but costs much more

That’s it.

More Info

This sleeping bag has SBS zippers and they don’t catch and feel robust.

The main side zipper is on the left side.

The sleeping bag has a baffle around the neck area, which can be tightened via the toggle (a baffle is a puffy section of material, created for comfort and to stop air from getting into the bag).

The label states that it’s best to wash by hand but it can be machine washed. It can’t be dry cleaned:

Note the baffle near the neck area, there’s another next to the zips: These keep drafts out
