Mountain Warehouse Summit 250 Sleeping Bag Review

What Are You Buying?

1. 3-4 Season Sleeping Bag

The Mountain Warehouse Summit 250 sleeping bag falls somewhere between 3 season and 4 season sleeping bags. It is heavier and warmer than a 3-season sleeping bag, but not bulky and warm as a full winter sleeping bag.

This gives the bag a nice warmth to size ratio. It can keep you warm in fairly cold temperatures, but still lightweight enough to easily carry around. It’s a great choice for people who love to camp in autumn and winter but don’t want to lug around a bulky sleeping bag. 

The Mountain Warehouse Summit 250 has three temperature ratings: 

• Comfort temperature of 5°C — this is the minimum temperature at which the sleeping bag is designed to keep most people comfortable. 

• Limit temperature of 0°C — between 0 and 5°C, the sleeping bag may still feel comfortably warm for naturally warm sleepers (limit temperature ratings usually apply to men since they sleep warmer). 

• Survival temperature of -17°C — this applies to emergency situations only. The sleeping bag should not be used frequently in such low temperatures. If you often go camping in extreme temps, get a 4-season sleeping bag instead. 

2. Hollow Fibre Insulation

The Mountain Warehouse Summit 250 sleeping bag consists of hollow fibre insulation and polyester fabric on both the outside and inside. Not exactly a luxury sleeping bag, but good enough for the price.

The synthetic insulation is warm and keeps you insulated even when wet. That’s good considering the Summit 250 is not waterproof.

3. Can Be Zipped to Another Bag to Create a Double

Want to double up with your camping partner? You can buy two of these sleeping bags and zip them together to create a double. Just make sure you get one with a right-handed zip and the other with a left-handed zip.

4. Regular & Long Length Options + Multiple Colours

The Summit 250 comes in two length options. The regular length sleeping bag is 200cm long and is suitable for people up to 180cm tall (5’9”). The long length sleeping bag is 215cm long and is suitable for people up to 195cm tall (6’4”).

If you are taller than 6’4”, look for a longer sleeping bag to ensure your entire body is well covered.

In addition to sizes, you can also choose from 10 sleeping bag colours, including fuschia, orange, khaki, and blue.

How Comfortable Is The Mountain Warehouse Summit 250 Sleeping Bag?

The Summit 250 is pretty comfortable for a basic entry-level sleeping bag. It should keep you nice and warm as long as temperatures don’t dip below 0-5°C.

It has a mummy-shaped design that contours to the human form, which helps keep you warmer. The 2-way zip is easy to operate, though several customers say it snags easily even though there’s a zip guard. The sleeping bag also comes with a hood that you can tighten around your face and head.

The inner fabric is not the softest, so consider getting a soft sleeping bag liner for use with the Summit 250. It can also help keep you warmer in colder temperatures.

As for portability, the Summit 250 sleeping bag is easy to roll up into a tight bundle that fits into the included compression bag. It’s small and light enough to hike around with, making this sleeping bag ideal for both car camping and backpacking.

What Accessories Are Included?

The Summit 250 sleeping bag comes with a compression bag to store and carry the sleeping bag in. But you might want to get a different compression bag.

A number of customers say the stuff sack is too flimsy and tears easily especially when you are trying to push the sleeping bag inside. If you are getting this for backpacking, get a better quality compression stuff sack. Trying to hike with an uncompressed sleeping bag is a pain.

As we mention, also consider buying a microfiber or cotton liner for the sleeping bag to make the inside softer and cosier.

Pros

• Affordable and good quality sleeping bag.
• Ideal for 3 seasons and mild winters.
• Easy to use.
• Can be doubled up with another sleeping bag.

Cons

• Not suitable for extreme winter temperatures.
• Zip snags easily.
• Not ideal for taller than average sleepers (above 6’4”).

Anything Else You Should Know?

Keep in mind that everyone is different when it comes to sleep temperature. Some people feel colder in bed, while others naturally sleep warm.

If you are a cold sleeper, the Summit 250 sleeping bag might still feel a bit chilly even at the rated comfort temperature of 5°C. You can still get the sleeping bag, but look for ways to make it warmer. Here are a few ideas:

• Sleep in more layers or invest in good quality thermal wear for camping.
• Get a warm liner for the sleeping bag.
• Place the sleeping bag on a pad or mattress instead of directly on the ground.

Conclusion

The Mountain Warehouse Summit 250 is a great choice if you are shopping for a pocket-friendly sleeping bag you can use in all seasons and is easy to travel with.
