Weather and Wind:

  • Large stuff-it pocket on the front holds rain gear or other bulky items
  • Integrated, tuck-away rain cover stands ready to protect your load from sudden downpours


  • To take account of the narrower shoulder width of the female anatomy, and thus prevent slippage, the SL shoulder straps are both narrower and shorter in length.


  • Main compartment has plenty of room for an all-day hike; 2-way zipper on the front allows access to buried items
  • Lid pocket, valuables pocket inside and two kinds of side pocket (zipped and mesh) provide a variety of stowing solutions
  • No more rummaging around for your gear – the two-way zip on the front allows direct access to well-buried items, even when the lid is closed
  • Large Side Zippered Pocket


  • Mesh side pocket stores water bottle, headlamp, gloves or sunscreen; lid pocket holds a map, compass or GPS, spare batteries and other small items

  • Flexible Delrin Aircontact back system construction fits any back shape comfortably

  • Curving the SL waist belt wings. The frontal adjuster system feature of our larger volume rucksacks simplifies the waist belt fitting procedure.
  • Delrin frame provides stability with little weight. Follows the most varied movements with absolute ease. The frame combines with the body-hugging fit of the pack to create a comfortable, compact carry system with even load distribution and transfer
  • In order to give a perfect anatomic fit around the upper body, the SL shoulder straps are both narrower and shorter in length.
  • In general, the female waist and hip area is also shaped differently, so in order for the waist belt to deliver a perfect anatomic fit when fastened, it should ideally have a conical shape.
  • SL (Slimline) fit is specifically designed with narrow, short shoulder straps and short torso proportions for women


  • Aircontact pads in breathable hollow-chamber foam distribute load evenly. Aircontact pads perform a pump effect, whereby every movement prompts the exchange of air, resulting in optimum ventilation. 15% less perspiration than with other body-contour packs


  • Hydration-compatible design features reservoir pocket and drink tube exit port for on-the-go hydration (reservoir sold separately)


  • Elasticised toggle straps double up as compression straps
  • Soft edges to the straps, smaller buckles and narrow tapered strap ends prevent the SL shoulder straps from chafing under the arms and eliminate pressure points in the chest area.
  • Anatomically formed 3D AirMesh shoulder straps with load transfer straps
  • Stabiliser straps allow optimal positioning of the backpack.


  • On average, women's backs are not quite as long as men's. The SL carry system is thus slightly shorter than that of Deuter's standard rucksacks. Conse quently, the models in the SL series are the ideal choice, too, for male users with shorter backs.
  • This conical form is achieved by angling the belt diagonally upwards and by
  • Clever front design with large mesh pocket/helmet flap
  • SOS label
  • Wet laundry compartment
  • Anatomically formed hip fins for freedom of movement and body-hugging carrying.
  • Carrying Capacity = 20 lbs

Deuter Trail 20 SL Reviews:


Best Daypack w/o Trampoline Ventilation!

Recently, I've been trying to get my girlfriend, to include myself, properly geared up for hiking. We're starting to hike more often and the first thing that I wanted to do is replace her old trusty and outdated JanSport.

Based on my experiences in the Marine Corps, I know how important it is to carry a pack that not only properly fits my body, but also serves its intended purpose while still being versatile. I've also had many female Marines in my unit, so I'm well aware of the problems that they encountered with military-issued packs.

I have a bit of an obsession when it comes to having the best gear so I spent a few weeks researching for the perfect daypack for my girlfriend. Her criteria was simple, comfortable and ventilated. Based on the things we actually carry and pack in our day hikes, I wanted to get a small daypack in the 20s-liters range. It didn't take long for me to narrow my search down to three brands: Deuter, Gregory, and Osprey.

For Deuter, I chose the ACT Trail 20 SL and the Futura 24 SL. The SL means Slim Line, it's a one-size-fits-all for women and also meant for men with shorter backs. One thing to note about most Deuter packs is that they're not adjustable when it comes to torso length, except for some of the larger packs. Deuter has one size for every model, unlike Gregory or Osprey packs, which has different sizes (small, medium, or large) for most models.

For Gregory, I chose the Jade 28, size small to accommodate torso lengths between 16"-18". The small size is actually 26.5 liters in volume.

For Osprey, I chose the Sirrus 24, size small to accommodate torso lengths up to 18.5". The small size is actually 22 liters in volume.

Fortunately, REI sells these packs, which made them easy to compare side-by-side online. Regardless, when it came to the specific size and color, not all of them were available in my local REI stores. So, the best thing for me to do next was to purchase all of them online so my girlfriend can actually try them on in person.

Upon delivery, we immediately tried them all. Our first impressions were that the Deuter packs looked the coolest, thanks to their color schemes and tactical appearance. As for the Gregory and Osprey packs, we weren't too fond of the color schemes and the oddly shaped appearance of their designs.

All of the packs had a trampoline-style ventilation except for the Deuter Act Trail 20 SL. We took that one aside to compare later on once we narrowed down which of the trampoline-style packs we like best. We tested all of the packs by filling them up with 10 pounds of gear and a small pillow as a filler. We then walked up and down the stairs, and back and forth around the apartment. We tested for comfort and were not too concerned about the weight as they all felt relatively light to us.

Out of all the trampoline-style packs, we liked the Osprey pack the least because it lacked overall padding. The padding on the shoulders and waist/hips were thin and not as comfortable as the Deuter and Gregory packs, not to mention that it had no back padding at all on the trampoline. We also found that the Osprey Sirrus 24 fell short on features compared to the other packs. So the Osprey was out.

Between the Deuter Futura 24 SL and the Gregory Jade 28, the Gregory felt the most comfortable, mainly because of the lumbar support (the padding on the lower back). We quickly grew fond of this feature because it straightened our backs upright and helped us walk and ascend (up and down the stairs) with better posture. To simply put, it felt great and we welcomed it. The Gregory pack also appeared to have better craftsmanship, which is by no means a question in quality against the Deuter packs as they too appeared well made.

We didn't like the design on the Gregory pack at all, it just felt too odd as if it tried too hard to reinvent the wheel. We hated the center compression strap because it never fully compresses the pack, which left the upper portion of the pack really baggy. Overall, we didn't like the way the features were designed on the Gregory pack, everything was just odd, not useless, but odd. The color schemes were not very favorable to us either. Needless to say, the Gregory pack was the most comfortable, barely, because of that lumbar support.

On the other hand, we felt that the Deuter packs, both the ACT Trail 20 SL and the Futura 24 SL had the better features. We loved the sleeping bag compartment on the Futura 24 SL and the top/panel loading and front access of the ACT Trail 20 SL. Both Deuter packs compresses very well and compact, not baggy like the Gregory pack. As I mentioned before, we felt that the Deuter packs had a much better color scheme, but that's all subjective.

When it came to the trampoline-style ventliated packs, we preferred the Gregory Jade 28, unfortunately. My girlfriend and I really wanted to choose the Deuter Futura 24 SL over the Gregory pack, but we felt that comfort ruled over features, looks, and everything else. The Gregory Jade 28 was more comfortable merely because of its lumbar support, which really made the difference. Also, the Deuter packs, especially the Futura 24 SL, restricted head movement when it came to looking up because of the pack's internal frame which gets in the way of tilting your head back. I believe that's a common issue for top-loading packs.

Between the Deuter ACT 20 SL and the Gregory Jade 28, unfortunately again, we chose the Gregory pack. At this point, we felt that they were two very different packs. The ACT 20 SL didn't restrict movement in the head as much as the Futura 24 SL did, and out of all the packs we tried, we felt that this pack had the best features for its size, and the best color options (black or apple-moss). We loved the slim design and overall compactness of the ACT Trail 20 SL, even though we ended up hesitantly choosing the Gregory Jade 28 for its lumbar support and trampoline-style ventilation.

If you prefer a smaller daypack and are not big into the trampoline-style ventilation, then by all means, look no further and get the Deuter ACT Trail 20 SL. Also keep in mind, in our opinion, the only thing the Gregory Jade 28 has going for itself over the Deuter Futura 24 SL is the lumbar support and the whole looking up issue, which is a very small trade-off. If you're big into features over comfort, which is only a slight trade-off, then by all means, go for the Deuter.

I hope this helps!

This pack was AMAZING. I took it on a 4 days hiking trip to kauai and it was perfect for 4 days straight of hiking. I felt like there was barely any weight on me and i had tons of gear. It may look small when you see it but believe me you can fit pretty much everything you will need! i would never chose any other pack. Great for day hikes and long trips..just hook a sleeping bag on and a one person tent and your good to go. I hiked miles in the hot sun with this and it was no problem. the waste belt helps a TON,,,if your shoulders start feeling tired and begin to hurt losen the straps and let the hip belt do the rest. seriously cant say enough good things about this will for sure be my new adventure pack. rain cover at the bottom is great thing to have too.

Perfect for a man, too

This backpack is marketed for women but it works great for men, too.

I understand that it's calibrated to fit women's bodies better, but being a man of 6ft, 180 lbs, it fits me very well. The straps are comfortable, the ventilation system keeps me very cool and it's the best looking pack around. Needless to say, nothing feels "feminine" or "masculine" design wise.

The compartment feels narrow but access to the bottom is easy with the two way zip. So, I'd say it's perfect for half day hikes or commutes. Anything more, you might be wishing there's more space.

Highly recommended for both men and women!

Great daypack

I was looking for a daypack to use for afternoon hikes instead of my 60L pack. I was worried that 20L was going to be too small but it is just right. I can put the hammock and the dog's gear in with lots of extra room. The great part about this pack is that it has all the features of a large pack but in a daypack size. If you have compact gear you could even use this pack on an overnighter without a problem. The only thing I wish it had was a pocket on the hip belt but all the other features makeup for the missing pocket.
