Performance

I often find myself in situations where I need to bring ice and cold drinks somewhere but I don’t always have a free hand to carry a cooler or smooth surfaces to wheel a cooler to where it’s needed.  I often go camping or set up a club tent to spectate at triathlon races, and both of these situations don’t lend themself to a traditional cooler.

RTIC sent me both the 24 can and the 48 can Ultra-Tough Backpack Cooler for testing.  My main testing of these coolers was during a 3 day long triathlon training camp, where we camped at the venue and trained during the day.  The coolers were left outside for over 48 hours straight. Each cooler had 16 lbs of ice placed inside during the duration of the camp.

Out of the box, these coolers are incredibly well made.  The exterior and interior are made from a smooth, heavy-duty waterproof material.  The zippers are substantial.  They are waterproof, which makes them a little challenging to open and close without a little muscle (I would expect that this gets easier over time).

The RTIC Cold Lock Press Lid is well designed.  The lid has the same depth of insulation as the walls, and you press the lid down into the top of the cooler to obtain a seal that’s good enough to keep things plenty cold for when you are in and out of the cooler frequently and don’t want to fuss with the zipper.

Carrying the RTIC Ultra-Tough Backpack Cooler is very easy.  Both cooler options have the same padded, adjustable backpack straps.  Once you’re at your venue, each cooler has a smaller strap, located near the top of the backpack straps.  This strap is big enough to grab and lift the cooler, say from the ground to bring it up to a table.

Also impressive is the insulation for the RTIC Ultra-Tough Backpack Cooler.  I over-estimated how much ice we would need for training camp (5 x 16 lbs of ice for 3 coolers).  Each RTIC Ultra-Tough Backpack Cooler (24 can and 48 can) got 16 lbs of ice placed inside it Friday evening.  This ice would be used for drinking and filling water bottles (versus keeping drinks cold).  This wasn’t a complete apples-to-apples comparison, as the 24 can cooler was FULL of ice and the 48 can cooler was about 2/3 of ice (there was air taking up 1/3 of the larger cooler).  When we packed up Sunday at noon, the 24 can cooler still had most of the 16 lbs of ice intact after staying outside for nearly 40 hours, which is really impressive.  The 48 can cooler had about 1/3 of the original ice remaining by Sunday, but I feel strongly that if we had fully loaded it with ice, the results would have been similar to the 24 can cooler.

The RTIC Ultra-Tough Backpack Coolers remained leak free during the testing.  Any dust on the outside easily wiped down.  Once home and drained of liquids, both coolers cleaned up easily via evaporation and a quick wipe down.

The main consideration in choosing the RTIC Ultra-Tough Backpack Cooler is which size to get.  The 48 can cooler is obviously larger, which means there’s more room for ice + drinks, but it is also substantially bigger, and as a result heavier.  Wearability is also a consideration, as the larger cooler is longer.  The 48 can cooler takes this into account by including a weight-loading waist belt, but shorter users may still find the cooler a bit overwhelming.

For sizing and wearability comparison, I’ve taken photos of each backpack on both myself and my husband, Will.  I’m 5’4″ and he’s 5’11” as a point of reference.  I find that I can handle both coolers, but I’m also used to wearing ridiculously large backpacks.

Closing Thoughts

The RTIC Ultra-Tough Backpack Cooler is a fantastic option for when you need a hands-free way to bring ice and cold things to your summer activities.  This cooler is great for camping, gatherings away from a parking lot, or time at the beach.

Erin is an adult-onset athlete who started as a Masters Swimmer and then developed into a triathlete.  She has completed 5 Ironman races and nearly 20 x 70.3 distance Ironman races, including the World Championship in Lahti, Finland, in 2023.  In 2025, she raced for Team USA in Pontevedra, Spain for the World Triathlon Cross Tri World Championship. She placed 9th in her age group and was the 1st American woman in her age group.
Somewhere along her triathlon journey, she picked up deep love of cycling. Cycling encouraged her to see landscapes in a new way, learn new skills and to develop self reliance; now she often goes and does Type 2 rides just to see if she can do it.  She’s got all the bikes: gravel, mountain, fat bike, time trial and road.
She is even known to combine her love of camping and cycling and go off on solo 24 hour overnight bikepacking trips in the mountains of Colorado. In addition to bikes, she teaches yoga, lifts weights, skis, SUPs and has recently purchased a campervan.

Erin is a former Montana park ranger with a degree in environmental engineering.  She loves getting into technical details while putting her gear (and herself) through the paces. She shares her home in Colorado with her husband, Will, and her 3 cats (Zipper, Brewtus, and Simcoe).
Fall and winter 2025 will bring Erin to the “Adventure Side”, with many camping, vanlife, bikepacking, and mountain bike rides. Once the snow flies, she can be find resort skiing, fat biking, and triathlon training (inside and outside).
In 2026 Erin took the National Championship in her Age Group for the USA Triathlon Cross Tri. She’s also racing the a National Championship Road Sprint and Olympic Distance race in Milwaukee and a few other off road triathlons and bike races.  In 2027, she will represent Team USA at the World Championship Cross Triathlon in Edmonton, Canada. She’ll also save lots of room for adventure time with her friends and husband.
When not adventuring, she can be found on a sunny patio somewhere, drinking beers with her husband.
