I recently took the Osprey Kestrel LT on a long-distance hike around Santa Maria Island in the Azores. This was my first time using an Osprey pack, and I really enjoyed the experience. After reading reviews of the Kestrel and the Kestrel LT, I decided to go with the newer LT for the simple reason of wanting to keep my pack weight lower.

Throughout the trail, the pack did great. I particularly liked the AirScape suspension system, which kept the load close to my body and provided a bit of ventilation. As it comes in many sizes, from 28L to 65L, the pack has a version for every trail type.

Testing the Kestrel LT

The hike around Santa Maria was five days from hut to hut. Because of that, I took the Kestrel LT 45, as I didn’t need to carry any camping gear, but had a lot of rain layers, and I actually also had my laptop with me for some work in the evenings.

We were lucky with the weather for the most part, and only had one short afternoon storm on the third day. Otherwise, we had sun! Hindsight is definitely 20/20, and I know now I probably could have taken a smaller version of the bag instead, since my rain clothes sat unused and pushed to the bottom of the bag for the most part.

As we hiked, I found that the bag did a great job of weight distribution; the huge amounts of water I was carrying felt weightless. Often, when backpack brands create lightweight versions of their lines, the comfort factor can decrease because of how they shave down the materials. But this wasn’t the case with the Kestrel! The straps and hipbelt were still very well cushioned, they didn’t sacrifice anything with the AirScape, and there were still plenty of pockets and organization options.

About Osprey

Osprey was born in California in 1974, at the seat of a single sewing machine, with a head full of ideas and a desire to design and build innovative backpacks to the highest quality. Today, Osprey products continue that pioneering spirit, trusted on the highest mountains, the remotest islands, and everywhere in between. They believe adventure isn’t reserved for a few — it’s open to everyone, and it can be found wherever there is the willingness to look.

The company is also a member of the European Outdoor Conservation Association, where they sponsor projects in the Lesser Caucasus mountains in Georgia to give back to the environment and community.

About the Kestrel LT

The Kestrel LT is the lightweight version of the classic Kestrel line from Osprey. The bags don’t sacrifice features for weight, though! The difference in weight from the Kestrel 48 and the Kestrel LT 45 is about .2 kilos, so it isn’t a huge difference. Instead, it’s a difference in streamlined design. The LT’s top lid compartment is fastened and cannot be adjusted on the back panel, while the original design does allow for adjustment. This doesn’t make a large difference, unless you have the bag stuffed very full and need the lid to adjust to the load. Likewise, the water-bottle side pockets are stiffer. This helps keep your bottles from falling out when you bend down or are scrambling, but at the same time, it can be difficult to access them if the pack is super full.

The perks of the bag are that it remains comfortable and is lighter-weight. I think it’s a great bag for when you’re not needing to carry a very full load and are out for a few days. It’s also a great choice if your kit is mainly classic gear that isn’t ultralight. It will do a good job of distributing the weight and keeping your hike comfortable.

Conclusion

The Osprey Kestrel LT was a great pack for our 5-day hut-to-hut tour, and I will definitely continue using it for future long-distance treks. I was really pleased with the design and could feel the quality and longevity of the company’s commitment to creating great products.

If I had to choose between the Kestrel and the Kestrel LT (without having tried the original), I think I would stay with the Kestrel LT. It’s marginally lighter, but it’s the fact that the features are more streamlined that I like the most. I don’t need extra straps and buttons hanging off the bag, and prefer it when it is simpler like this. All in all, I recommend it!
