Do you need a modular backpack? We tested the Baltoro Impetro, and weight the pros and cons

Modular backpacks are trendy, but are they for you?

The bills itself as a “complete ecosystem” for mountain sports. The modular backpack, which fits in three pieces, is part of a more significant trend stirring up the outdoors, sports, and travel realms. But do you need one?


The gear system has many options, from a single bundle (single backpack) to a complete bundle (four sacks). You have a base unit that can be customized depending on what you’re up to. It’s all about adaptability and limiting materials, pros for the multi-sport enthusiast and environmentalist alike.

All packs zip directly onto the base unit. The morphing luggage is intended to appeal to all outdoorsy types, like bikers, hikers, and skiers. Whatever your intention, the bag adjusts accordingly, at least in theory. On a recent road trip, we tested the Baltoro Impetro complete bundle and gave it some proper exercise on the trail. This version has four packs: a 10-liter hiking pack, a 15-liter biking pack, a 22-liter ski pack, and a 33-liter mountain pack. Designed in Austria, the system has garnered some serious buzz from adventurers.

Here are our takeaways.

On the surface, a modular system seems like a gimmick. Rest assured, however, as the packs are unique and tailored to specific sports. We quickly grew to appreciate the idea.


First off, it’s straightforward to swap out packs. The zippers are sturdy, and the materials are high quality. The base unit is comfortable, offering ample padding and support. One of the best features is the magnetic buckle, which holds fast and can be easily used, even in gloves. The hydration zone is well-placed and compatible with almost any vessel you have.

Let’s begin with the smallest pack, built for hiking. The exterior is water-resistant, and there are two water bottle holders. While there are few pouches, they are helpful. The petite pocket at the top is lined with soft material, making it great for valuables and just big enough for your phone. The volume is adequate for day hikes, with plenty of room for lunch, extra shoes, a rain jacket, and other gear. You understand how well the buckle and straps work on a hike or trail run on the base unit. The stability is impressive, something many backpacks have yet to master.

The biking pack is especially great for mountain bikers. From the sizable top pocket fit for goggles to the tool pocket and exterior helmet sling, it covers all the bases. There’s a side pocket ideal for snacks, and the pack itself wipes down quickly after a muddy ride. There’s a pump pocket and, arguably the most remarkable feature, a rain cover at the base that pulls out like a parachute when needed. Two main pouches make up the core of the pack, the larger of the two with internal velcro dividers, offering more than enough room for your biking supplies.

Handy tech advancements

The best of the bunch is the ski pack. It’s set up with Recco technology if you get stuck in an avalanche, and safety notes are added to the bag’s liner. The helmet holder is plenty big, and there’s a home for everything, including skis or snowboards, poles (with a bungee system), goggles (a soft-lined pocket), probes, and shovels. It’s a sleek overall size with all the volume needed for a sport requiring a bit more gear without weighing you down on the powder.

If there’s a weak link, it might be the mountain pack, but it still has many positives. The molle webbing allows many attachment permutations, while the hood pocket is excellent for handling camping gear or extra winter clothes. There’s an ice axe holder if winter adventuring is your thing, and even when jam-packed, the backpack feels great in tow.

Thankfully, there’s not much to like about the system. Here are some things you may (or may not) consider drawbacks.

One size may not fit all

We could see a more petite person struggling with the base unit. The one-size-fits-all approach makes a lot of sense, especially from a materials-saving standpoint, but the padding placement and strap system could be an issue for somebody with a more petite frame.

Compartments & pockets

The packs themselves could use a few more specialized pockets, given the volume at play, but the brand accommodates all of the general gear you’d want while biking, hiking, etc.

This pack is on the smaller side

Lastly, the mountaineering pack is a tad undersized. Most in the category come in at a larger volume. This one is expansive, but things could get tight (or bogged down with clip-on) depending on the length of your adventure. Upon first or second use, it’s easy to accidentally unzip the whole unit when you’re trying to access the pouch pockets, but that’s quickly remedied once you realize all of the pack pouches are highlighted with yellow-looped zippers (which we like, as the loops are prominent and accessible, again, even wearing gloves).

Modular ski backpack.


This is a great system that has very few flaws, if any. The price is reasonable, and the versatility of the packs is impressive. Lightweight, functional, and designed specifically for the sport at hand, these packs are highly recommended for outdoors people, especially the mountain-lover who loves to bomb down a hill on a bike or carve in the snow. Much thought went into creating the Impetro, and the dream was pulled off thanks to quality craftsmanship and dependable materials. We get the sense this system is built to last. If you’re a weekend warrior with a knack for various sports, we highly recommend the Baltoro Impetro modular backpack system.

Best 4th of July grill deals: Save on Traeger, Blackstone and more
An opened Classic Joe III with food cooking, from Kamado Joe.

Are you ready for the full intensity of the summer ahead? We can already predict that this summer will be hotter than usual, but that also means that it will likely feel longer. As a result, there are going to be more evenings and, later, great autumn days to be outside and spend time with our families. At least, that's what we hope. Taking advantage of 4th of July grill deals, then, will be an excellent way to celebrate. Whether you're looking for traditional grills and smokers, charcoal grills, or even gas grills, there are great deals to take advantage of right now. The following are our favorite for this season.
Coleman 4-in-1 Portable Propane Camping Stove — $70, was $125

This one is a bit tinier than the rest, with only a 100 square inch cooking surface, but its got a price and versatility level to match. With a tripod base and a small 14.4 x 10.5 x 13.9 inch body, you can easily take this will you and set it up on any bench. It has versatile cooking modes that include a grill, grill, wok, and even stove. It's recommend for groups up to four, but with a bit of raw veg and good drinks, we're sure you have the ingenuity to stretch the meal to five or six. This is not an advanced grill, but it doesn't have to be if you're looking to be on the go.

Home Depot 4th of July Sale 2024: Best home and garden deals
The Magic Chef 27-lbs Countertop Ice Maker next to iced drinks.

The 4th of July marks America's Independence. For adults, who haven't been firmly out of school for several weeks by the approach of the holiday, it also marks a sort of in-your-face realization that summer is truly and actually here. And for manufacturers and retailers, it marks one of the best times to attract customers to buy things for the outdoors. That could mean the best Blackstone cooker, a different 4th of July grill deal, or even an outdoor Jackery solar power generator. Yet it could also be the time to finally get one of the best cordless drills and start your wireless, battery-powered power tool collection off to a good start. Whatever your plans this summer, you should know that Home Depot is having a pretty massive sale to celebrate. Here are the home and garden deals that you should be on the lookout for to get your summer moving.
Magic Chef 27 lbs. Portable Countertop Ice Maker — $99, was $159

It's summer, and if you haven't used your refrigerator's ice maker in awhile, you may notice that it's pretty yucky smelling at the start of the season, slow, and extremely non-portable. This stainless steel ice maker goes with you and starts making ice fast, very much unlike sticking a try in the freezer. Just put some water into it and within the next seven minutes you'll have your first nine cubes. Not 27-pounds itself (that refers to the weight of ice it could, theoretically, make in a day with constant use) this little ice maker is a mere 12.1 x 9.5 x 14.1 inches (HWD), making it perfect for small spaces.

Anker Solix F3800: What you need to know
Anker Solix portable power station

I have a confession to make: I care about the way my portable power station looks. Sure, a power station is not something you would generally care about when it comes to looks. It is, after all, most likely sitting in your garage alongside other clutter and items you might keep there. But I consider my garage another room of the house, and I made sure it looks that way, intentionally. Design and functionality are important to me, so that’s why I fell in love with the Anker Solix F3800 when I first saw it. From a distance, with the handle extended – and if you squint just so slightly – you’d think you were looking at a Rimowa carry-on luggage.

Portable power stations are all the rave these days. They come in all sorts of shapes, sizes, features and storage capacities. And even at the smallest sizes, they can be incredibly heavy. So you can imagine what a power station meant to back up your home would weigh (hint: the Anker Solix F3800 is over 100 lbs).
