Product Description:

When going out for the day or a quick trip, we found that our current backpacks were unnecessarily big for this job. We needed something smaller and more compact, while still being able to take all the gear we need. The CTUG-25 aims to solve this. The main 20 liter compartment is more than enough to carry gear for a day hike up the mountain or deep into the woods, or even an over-nighter.  The exterior of the bag features 3 lycra stretch side pockets: 2 for water bottles and one large front pocket for storing quick access items like a water filter or jacket. The pack also features a zippered pocket to help organize loose items. The pack has our standard daisy chain shoulder straps and lets you easily add any of our shoulder strap accessories.  

The pack is also designed with a removable hip belt. This is easily taken on and off by sliding the webbing of the hip belt through tri-glides on the backpack. This allows for better weight distribution to the hips for longer hikes or during a heavy carry.

NOTE: Backpack shown first photo (navy and grey) is an older model. The yellow/grey pack is current.

Tech Specs:

Capacity: 25 liters total, 20 liters internal and ≈5+ liters external  

Weight: Currently 1 lb 5oz with sit pad and assembled hip belt

Dimensions: Main compartment is 10.5" x 6" a the base and 20" tall, with the roll top above that.

Materials and Water Resistance: We use X-Pac VX21 as we believe it has the perfect balance between lightweight and durability. It is a waterproof material however we do not seal the seams. This means that during heavier rain, water can and will seep in through the seams. We advise that you use a compactor or contractor bag as a bag liner to avoid your items getting damp. We will include 1 compactor bag with each purchase if you request it.


Roll Top Closure: Roll top creates a water resistant closure, while giving you the option to overpack the bag a bit if needed. Roll top clips into buckles on the side of the pack for a compact design

Side and Front Lycra Pockets: Lycra stretch pockets with elastic tops provide good compression on water bottles and other gear to help keep things in place as you hike.

Front Panel Water Resistant Zipper Pocket: There is a water resistant zipper pocket on the front of the pack large enough for a wallet/keys/phone.

Sit Pad: Removable sit pad acts as cushioning for your back while hiking, but is easily taken out when its time for a break. 

Shock Cord Sides: Shock cord on the sides will provide side compression if needed, as well as a place to attach small items, or secure tall items placed in the lycra side pockets such as your trekking poles.

Daisy Chain Straps: Shoulder straps are the standard daisy chain style as our full size backpacks. This means that any of our shoulder strap accessories can be easily added on. 

Strap Shape:

S straps: S straps allow more space for the shoulder/chest region and are preferable to women and men with large shoulders/chests. 

J straps: J straps are rather standard and will conform to most men and some women.
