TACT Bivvy vs SOL Bivvy: Head to Head Comparison


I took the bivvies out of their pouches and began working my method by testing them out.

The very first thing I did was to put them out facet by facet on the bottom. You might discover that they appear nearly similar. In reality, by all appearances, they’re.

They are each orange on the surface with the seams sealed in black “tape.” It could also be troublesome to inform within the image however for what it’s value, the SOL Bivvy is a barely darker orange over the TACT.

In phrases of dimension, these two bivvies are similar. Both measure in at 84” x 36.” It doesn’t matter which one you select as each will provide ample inside house for nearly anybody.

Verdict: Both are the identical dimension. Both provide ample house. No clear winner.

The Elements

The TACT and the SOL are each marketed as being windproof in addition to waterproof. While each bivvies had been laid out on the bottom I poured roughly one half of a gallon of water onto the surface of every of them.

I allowed the water to pool up and sit for about ten minutes, periodically spreading the water round with my hands. 

After ten minutes, I rigorously guided the water to the facet taking care to not get any close to the opening. I then reached in and felt all through the inside of each merchandise. Both had been bone draw on the within. 

Verdict: Both maintain dry. No clear winner.


To take a look at out how effectively these maintain an individual heat I made a decision to attend till dusk when the surface temperature was highly anticipated to drop to simply above fifty levels.

While this isn’t bitterly chilly, it’s chilly sufficient for publicity to be an issue. To take a look at these out I opted to put on inappropriate clothes. I wore shorts, a t-shirt with a zip-up hoodie, socks, and tennis footwear. (I wish to be aware that I performed this take a look at in a protected and managed surroundings)

I first crawled into the TACT and wouldn’t you realize it, it began to rain. I pulled the bivvy over my head like a hood and tightened the surplus thing beneath my chin. I sat within the rain like this for about thirty minutes. Every couple of minutes a slight breeze kicked up and the one place I felt the chilly air was on my uncovered face.

At just a few points throughout the take a look at, I did reach across the inside with my hand and will really feel the fabric turning into barely damp. Since these luggage are purported to be waterproof that additionally means moisture received’t depart the bag. This can result in condensation increase inside, because the packaging signifies. 

While I used to be not sizzling within the sleeping bag I used to be comfy. More importantly, I used to be not chilled or shivering.   

I received out of the TACT Bivvy and allowed myself to chill off. This didn’t take lengthy as I used to be not in preferrred clothes.

After cooling off I then crawled into the SOL Emergency Bivvy for a similar period of time. The outcomes had been the identical as they had been for the TACT Bivvy.

Verdict: Both stored me dry. No clear winner.


My greatest downside with older emergency blankets is that after the fabric was punctured, it was infamous for ripping as if it had been constituted of tissue paper. 

While I perceive that these emergency blankets or bivvies are supposed to be extraordinarily light-weight and compact they do must be considerably sturdy. The actuality of the scenario is that when somebody goes to be utilizing one among these they are going to be sporting out of doors clothes, footwear or boots, sitting on the bottom, shifting round, and many others. So whereas I don’t count on them to be ultra-tough, I do count on them to not shred to items when there’s a gap or tear within the thing. 

I ran two very fast checks to see how the fabric would maintain up. Actually, three checks for those who embody after I was testing them out within the rain. 

The very first thing I did was to see how the fabric would react to me urgent a finger by it. On each of the bivvies, the fabric did stretch out much as a heavy-duty trash bag would. Eventually, my finger did undergo the fabric.

I then used my pocketknife and lower a small tear close to the sting of the bivvies. Again, I used my finger to press by the outlet. Surprisingly, the SOL held up barely higher. As I pushed my finger by the outlet it continued to get greater, however the thing stretched greater than ripped. The TACT began to tear greater than stretch. 

I believe that each bivvies did effectively within the sturdiness take a look at, however the SOL didn’t appear to tear as much. One take away from that is that since each of those merchandise do stretch when they’re punctured, they need to maintain up decently to being repaired. What does this imply? Be certain to all the time carry duct tape in your survival kits.

Verdict: SOL assist up higher to my sturdiness checks.

Pouches Water Test

I do like to check out all the items of substances and on this case, meaning the pouches. The very last thing I used to be interested in was if the pouches would maintain water for any period of time. In a survival scenario every thing must be used to its fullest capability and figuring out if the pouches might be used as a water container might show helpful. 

I hung each of the baggage from a tree and crammed every one with water. Sadly neither of the pouches held the water because it ran proper out of the underside though the SOL pouch did drain slower.

It might be a superb factor that the pouches don’t retain water. This method a moist bivvy would have a greater probability of drying out. This take a look at has no bearing on the product itself, it was executed merely out of my curiosity.

In phrases of affordability, each merchandise price about the identical with the TACT Bivvy being the costlier one, so value actually isn’t a problem.

The TACT Bivvy does include an honest emergency whistle and the hearth tinder wire drawstring which is sweet. 

But when simply the bivvy, each are windproof, waterproof, warmed up in the identical timeframe, and supplied the identical quantity of house.

The solely distinction I skilled was within the sturdiness take a look at. It was right here that I believed the SOL carried out a little bit higher as a result of its thing had extra stretch to it earlier than breaking and it didn’t “rip” as much.
