Senior Gear Analyst Ian Krammer fell in love with this bag over two dozen nights of automobile tenting and backpacking throughout the Colorado Rockies in summer season and fall. With a comfortable really feel, superior options and a flexible design, it earns an Editor’s Decide on our tenting sleeping luggage information.

The Enhance 650 has a middle zipper that expands the cosy mummy form to a roomy rectangular match – good for staying heat whereas backpacking, or spreading out when automobile tenting. It additionally has two armhole zippers. This design allow us to maintain our shoulders and heads heat whereas reaching our arms out to maneuver gear, modify our sleeping pad, and even learn a e-book. Mushy nylon material, draft collars, and a large stash pocket add to the consolation.

That stated, all these zippers can really feel like a bit a lot. This design is nice for adaptability, but it surely’s overkill should you favor a easy, no-fuss sleeping bag. It’s additionally not as heat because the consolation score suggests and the mum hood is a bit shallow, too, so we’d save this one for the 40-65°F vary. Lastly, the Enhance 650 is a bit spendy. That stated, it’s on the high of our checklist for a motive: this factor presents excellent versatility that few different fashions can provide. If you need top-tier customizability and packability over simplicity, that is the one for you.

Consolation

The Enhance 650 earns high marks for consolation from our testers due to its distinctive, comfortable options. Our favourite? The Enhance 650’s distinctive means to unzip down the center. This zipper permits it to develop from a cosy, restrictive mummy that retains warmth higher to a extra roomy, rectangular form for extra room total. Senior Gear Analyst Ian Krammer is a really energetic sleeper, and the additional inches felt like a revelation on hotter nights switching between his aspect, again, and abdomen. 

We’re additionally large followers of two zippered holes on high. They double as vents for dumping warmth in addition to armholes. We liked with the ability to stick our arms out whereas conserving our torso’s heat. Ian used these to learn a e-book, scroll his cellphone, and extra. The Enhance 650 additionally has inclusive sizing together with quick, common and lengthy, in addition to in huge sizes for every size. There’s a match for almost everybody.

That stated, all these zippers generally is a problem whenever you simply need to crawl into the bag to sleep. A number of instances, we’ve returned from a midnight lavatory break and unzipped the vent zipper or increasing zipper whereas looking for the principle zipper, which could be annoying. We discover the mum hood is nice for retaining heat, but it surely’s a bit cosy and shallow. And, although the growth characteristic creates extra space, it’s nonetheless not as roomy as bigger rectangular luggage constructed purely for consolation. If you need most stretch-out house, there are higher choices, however for a stability of consolation and packability, the Enhance 650 shines.

Heat

The Enhance 650 has one-of-a-kind air flow and warming options. A bag-length zipper on high permits it to develop from a smaller, heat-efficient mummy form – greatest for retaining warmth all the way down to 40°F – to a wider rectangle, greatest for hotter temps and extra airflow. It has two vents on high that may be opened from the within or outdoors, to not solely fine-tune air flow, but additionally function arm holes. Not like many mummy luggage, the full-length, 2-way aspect zipper extends all the best way to the footbox, providing you with additional management over airflow with out sacrificing insulation.

The draw back? Testing finds this bag’s temperature score is formidable. Ian slept on a frozen lake on this bag, mixed with two excessive R-Worth pads. The in a single day temperatures dropped to 27°F. To remain heat he nonetheless needed to placed on base layers, midlayers, and a puffy.

Nonetheless, these are small gripes. This bag is heat for many three-season tenting journeys.

Packed Dimension

Some sleeping luggage eat up valuable pack house, however not the Enhance 650. Regardless of its many zippers, it compresses to only 20 inches by 7.5 inches in its stuff sack, making it one of many smaller picks on our checklist. It’s additionally one of many lightest with regards to tenting sleeping luggage – solely 2 kilos, 11 ounces.

Therm-A-Relaxation consists of each a compression sack to squish the bag down tightly, in addition to a separate mesh storage sack to take care of loft when not in use.

It will probably’t be saved long-term in its compressed state, so that you’ll want to offer it house when not in use. Down additionally calls for particular washing steps in comparison with artificial insulation.

Options

The Enhance 650 one is filled with intelligent designs. Ian loves the twin vents that double as armholes, good for dumping warmth and reaching out of the bag shortly. A full-length zipper runs from the hood to the footbox, so we’re capable of stick our ft out on heat nights. An increasing zipper transforms the bag from a heat-trapping mummy form to a roomy rectangular format. Lengthy zipper pulls make changes straightforward, even with gloves on, and a snap closure on the high prevents the zipper from slipping open when transferring at evening.

We particularly love the outsized inside pocket – this factor is deep – that simply suits a cellphone, headlamp and different small necessities. All these design parts make it a great match for nearly any sleeping type or temperature desire.

However, all these zippers can really feel overwhelming, particularly at evening. When it’s darkish, determining which zipper is which generally is a little annoying should you favor a extra easy, no-fuss design. Moreover, Therm-A-Relaxation doesn’t embody any zipper plows, so zippers are vulnerable to snagging on the material. The inside pocket is spacious, but it surely lacks a closure, so smaller gadgets like chapstick and automobile keys can slip out in a single day if we toss and switch loads. That stated, if you would like an intensive characteristic set for the last word versatility, the Enhance 650 is among the greatest.
