Marmot Micron 40 Downwards is a low-weight (1.37 lbs) sleeping bag that uses down with a fill power of 650 to keep the sleeper warm and comfy.

Another cracking thing about this sleeping bag is that it packs downwards to just 6" x 12", as well equally the fact that it comes accompanied by a staff sack. One thing worth mentioning here is that getting the model out of this sack can exist a bit tricky the first time.

Unfortunately, Marmot Micron forty Downwards is far from perfect. While it'south certainly not equally characteristic-packed or well-designed as sleeping bags made by companies such as Feathered Friends, I notwithstanding call back that this model should have a draft neckband. Besides that, its attachment can be somewhat fiddly, just that'south non really a serious issue.

8. Nemo Forte 20 F

Pros:

• Provides a decent amount of warmth
• A expert bargain – relatively affordable toll
• Thermo Gills for quick & easy excess rut shedding
• Versatile & comfortable

Cons:

• The weight – a heavy & beefy sleeping handbag

The last summer sleeping bag I'm going to analyze here is yet another model from Nemo. This bag, nevertheless, features synthetic insulation merely it's not exactly lightweight – it is, in fact, pretty heavy and bulky. The biggest reward of this is that Nemo Forte is one of the most spacious synthetic sleeping bags on the market.

Amongst all sleeping numberless in this category, this model features ane of the warmer temperature ratings. It is, therefore, platonic for iii-flavour trekking – in nearly temperate climates, its synthetic insulation provides enough warmth to proceed the sleeper cozy during autumn and spring overnights. One peculiarly great thing most Forte's synthetic insulation is that a large percentage of it is made out of recycled materials.

Also the suitable temperature rating, another great thing about Nemo Forte is that it genuinely excels in the comfort category. The luxuriously roomy dimensions of this synthetic sleeping bag mean that you lot'll take a lot of infinite for wiggling if you lot're an average woman or human. However, this spaciousness comes at a cost – this sleeping bag weighs over iii.5 lbs for a size "Long".

Some other field in which this synthetic purse excels is versatility. It uses synthetic Primaloft RISE insulation and provides its user with a good corporeality of warmth fifty-fifty when it's soaked. I specially liked the inclusion of Thermo Gills, equally these allow sleepers to shed excess heat when they start to feel as well warm inside the sleeping bag.

Another first-class characteristic is the so-called "blanket fold", which is basically a flap made out of insulating material that can exist used equally a neck bamboozle.

Best Summertime Sleeping Bags Buying Guide

Temperature Rating

A well-made sleeping bag of this type will always be rated according to EN13537 ("European Norm"). Most manufacturers of these products often quote figures chosen the "Lower Limit" and the "Comfort Rating".

As its proper name suggests, the lower limit specifies the lower end temperature where a warm sleeper or an average male would still experience cozy and comfortable. The comfort rating, on the other hand, indicates a temperature at which an average woman, or a warm sleeper, would still feel comfortable and warm.

While it'due south certainly a subjective thing, a temperature rating can however be a pretty good guide when you're comparing one bag with another. If you desire to avert feeling uncomfortable during chilly nights at all costs, stick to the comfort factor while shopping for a summer sleeping bag. Go on in listen that you can ever open the zipper if you lot showtime feeling too warm, alternatively, a cold weather sleeping bag, non a zero caste pocketbook, might be a better choice.

Insulation for Warm Weather

The insulation in sleeping bags of this type will be either synthetic or down.

Downward is much ameliorate in terms of pinch and weight. However, down also has a major drawback – it takes a lot of fourth dimension to dry when information technology gets wet. This is why it's very of import to brand certain it's hydrophobic if you decide to get for a bag with this blazon of insulation. Another important matter to keep an eye out for is the fill up power – the college the number, the greater the insulating efficiency.

Synthetic insulation, on the other paw, performs a lot amend in wet atmospheric condition. Of form, there'due south a catch – you demand more of it to make the sleeping pocketbook adequately warm. This contributes to the pocketbook'southward overall weight and has a negative result on its compressibility.

When you're hiking in July or August, a lightweight down model volition weigh next to zilch and won't accept up too much room in your pack. If you really need to cut down on weight, you won't make a mistake by going with a down bag that weighs around 1 lb or a bit more.

The Zippers

Sleeping bags come up with a zipper that is located either on their left or right side. Which ane of these is a better choice? The answer to this question is actually pretty uncomplicated – if you're correct-handed, get for a sleeping purse whose zipper is on the left, and vice-versa.

To cut downwardly on the weight of their sleeping bags, some companies will equip them with ¾ zippers. While they tin certainly brand going in and out of the bag somewhat bad-mannered, they are fine for the almost function. On the other hand, full-length two-fashion zippers provide sleepers with much easier access. They also make shedding excess oestrus a lot more convenient and quicker.

An important thing to go on in mind here is that zippers tin easily snag and damage the outer material. Therefore, try to obtain a bag with some kind of anti-snag feature. A draft tube is yet another convenient feature to proceed an eye out for – information technology runs along the zipper'due south length and keeps the cold at bay.

The Shape – Rectangular or Mummy?

To improve warmth and cut down on weight, a vast majority of manufacturers of these products tend to go with the mummy shape. While these can certainly brand you lot experience overheated and somewhat restricted, they are better in terms of thermal efficiency when compared to their rectangular counterparts. If the surface area you often hike in gets pretty chilly at night, you tin can safely go with a mummy-shaped model.

Rectangular bags are improve for active sleepers – they provide more than space, particularly in the feet area. Get with 1 of these if having the room for wiggling is much more important to yous than having that snug, toasty fit.

The Toll

If you're someone who never camps in dank temperatures, or if you lot're someone who goes on hiking trips but occasionally, you lot won't make a fault past going for an affordable summer sleeping bag.

Notwithstanding, if you lot're a bit more than serious about camping and desire something rugged that will keep you cozy even during your autumn and jump outings, your all-time bet is to go for a 3-season bag. Depending on the features, insulation, temperature rating, and the material, these tin toll anywhere betwixt $100 to $400 and more than.

Other Things to Consider

Most of the models I've listed to a higher place are quite lightweight, just if depression weight is really important to you, your best bet is to go with an ultralight handbag such as Kelty Cosmic twoscore Caste or Rab Neutrino 200. Ounces add pretty quickly when you're hiking – if you lot're an ultralight trekker, you'll want to buy a bag that is as calorie-free equally possible.

When information technology comes to durability, pay special attention to how well the hood and the zipper of a particular bag are constructed. Too, brand sure that the bag's length accommodates your tiptop and that information technology comes together with a pinch sack.
