GORUCK has a very distinct design which people have come to know and associate with their brand. This design translates across their line of packs which truly does a great job building their brand recognition. One of the issues that comes along with this occurs if you choose to purchase a pack on the secondary market. It can be tough to tell exactly what pack (or sized pack) you’re looking at if you don’t know what you’re looking for.
GR1 (21L vs 25L) & Rucker (25L vs 20L)
In 2015 GORUCK discontinued the GR0 and merged it into the GR1 line giving the GR1 two sizes: 21 liters and 26 liters. Around this time the Rucker was released and came in two sizes as well: 20 liters and 25 liters. The only issue with this was that the initial tags on the two sizes were identical. This led to confusion for the buyer as there was no easy way to determine which pack they were looking at. If you had the pack in your hands then it was a little easier to figure out but if you were buying one second hand you had to hope that the seller was telling the truth or you knew what to look for.
If you have got a picture of the part of the pack that touches your back then you are in luck. Count the number of “panels” on there and you will have your answer. If there are nine panels then it’s a 26L GR1 or 25L Rucker and if there are seven panels then it’s a 21L GR1 or 20L Rucker.
The major difference between the 21/26 liter GR1 and 20/25 liter Ruckers is the height. Both of the larger packs are two inches taller than their smaller sibling. Using this knowledge and a ruler you can easily determine which pack you have in your hands. If you’re unsure which size you’re buying on the secondary market then asking for a picture with a ruler can reassure you.
To figure out which size GORUCK pack you have all you need to do is measure from the top of the slant pocket zipper to the first line of webbing. The 26 liter GR1 and 25 liter Rucker should measure to about 8 inches. The 21 liter GR1 and 20 liter Rucker should measure to about 6 inches. Above you can see the 25 liter Rucker measuring at about 8 inches.
Above you can see the 20 liter Rucker coming in at about 6 inches.
Here we have the 26 liter GR1 at 8 inches.
And finally here is the 21 liter GR1 measuring in at 6 inches.
GORUCK Bullet 10 vs Bullet 15
Due to the similar size of the Bullet 10 and Bullet 15 it seems some people have trouble differentiating them. If you aren’t sure what you’re looking at then count the number of rows of webbing there are on the outside of the pack. If there are three rows of webbing it’s a Bullet 10 and if there are four it’s a Bullet 15. In the above picture the Bullet 15 is on the left and the Bullet 10 is on the right.
Hopefully this helps you either figure out what size pack you have or what size pack you’re about to purchase. Curious what we think of these two packs? Check out our comprehensive reviews for the GORUCK GR1 and the GORUCK Rucker.
