In addition to the standard f-stop 45-day satisfaction policy, there is a 6 month workmanship warranty for the Dyota Mask to cover any defects in material. For additional information on warranty terms and filing a claim, please see our Warranty page.
Our 45-day satisfaction policy is offered for the return of unworn/unused masks in the original packaging. Think of buying a mask like buying a bathing suit. You don’t want to try on a suit (or buy a mask) that someone has already used. Connect with our Support Team for any assistance.
The bluesign® technologies group collaborates with factories and brands to reduce the human and environmental impact of textile-based production. They facilitate education to improve manufacturing processes to better utilize resources, ensure occupational health and safety of workers by eliminating hazardous chemicals and build safer working environments. They hold approved factories to stringent standards for pollution control. You can read more about bluesign® here.
Ag+ (Silver) Ion technology, such as the DuPont SILVADUR™ used in the Dyota masks, acts as an antimicrobial agent to effectively control bacteria growth by delivering silver nanoparticles to organisms which land on the treated fabric. These ions safely kill microbes and retain antimicrobial properties even after multiple washes. You can read more about SILVADUR™ here.
Quaternary Ammonium Salts, otherwise known as Q.A.S., is a smart antimicrobial treatment used in textiles. The properties of this compound provides a durable antibacterial defense.
In addition to being a washable and reusable item, the Dyota Mask uses bluesign® certified fabrics, incorporates advanced antimicrobial technologies such as Q.A.S. and DuPont SILVADUR™, and utilizes ultrasonic welding to provide longevity and comfort.
The simplest solution is to hand wash with mild soap and hot water and let air dry. Avoid applying any harsh chemicals which can degrade the materials and effectiveness of the mask. There are currently no strict guidelines on the frequency of cleaning fabric masks; general recommendations are to wash daily if worn frequently.
The Q.A.S. outer layer helps block large particles and kill bacteria, while the dense polyester center layer reduces particles and liquid droplet penetration. The inner knit provides a comfortable and breathable layer treated with DuPont SILVADUR™ for extra antimicrobial protection.
Unfortunately, there isn’t an easy answer to the question. We follow the CDC guidelines and most governmental suggestions.
NO. Cloth masks help to protect other people, not the wearer. People with COVID-19 can spread the virus before symptoms appear, and some people can have COVID-19 and never show symptoms. In both cases people can unknowingly spread the virus. If you are an unknowingly sick person, wearing a mask can help to protect others and slow transmission in our communities.

When balancing long-term value and quality, f-stop is not much more expensive than entry-level products selling to the same kind of customers. This is especially true when factoring in our modular design that allows a customized carry solution based on your needs, and bundling discounts which simplify the purchasing process.

When you take all of this into consideration, f-stop camera backpacks represent an amazing value and deliver a much higher return on your investment than any other camera backpack in the world.
The f-stop modular system is comprised of two parts – the insert and the pack. Unlike standard camera bags which have a limited amount of storage configuration, the combination of insert and pack gives our customers the greatest level of flexibility to carry the exact camera kit needed for any type of photography project.
From nature, to landscape, to video, to urban or travel settings, to drone, and even adventure sports, the interchangeable camera bag inserts are also useful as standalone carry solutions on their own, with the ability to be used as carry-on pieces during air travel, or even storage organization compartments when at home.

Our backpacks are weather resistant, not waterproof, which indicates protection from submersion. They can be exposed to light rain or snow for a short amount of time, however using a Rain Cover will add more protection.
f-stop Camera Inserts are weather-resistant, not waterproof. The insert provides padded protection and organization while carrying inside the pack or in storage. It’s not intended to be carried long-term as a stand-alone solution.
f-stop Ultralight (UL) packs are more compact than Mountain Series packs and offer a solution when nimble will be important. These camera packs are designed for camera gear and kits that are not very heavy, up to 7kg/15 lb, because they do not have heavily padded shoulder harnesses are made of ripstop nylon covered with 120 DWR coating, while the Mountain series have a 420 DWR coating.
The UL series is designed for shorter day trips and weather conditions that are not very harsh, while the Mountain Series can be used for longer trips and can be exposed to light rain for a small amount of time. The UL packs are meant for camera gear that is not very heavy, up to 7kg/15 lb. The biggest ICU that is recommended for the UL packs is the medium-sized one, because of weight limitations.
Both series have a harness system that is designed to help you better distribute the weight on your shoulders and waist. The 3 biggest packs from the mountain Series have extra padded shoulder straps that ease the weight on your shoulders. They also have an internal multipurpose sleeve that can fit up to a 17’’ laptop, while the rest of the packs can fit a 15’’ laptop.
The maximum comfort carry weight varies between packs as follows:
The listed measured pack volume includes all exterior pockets and compartments.
We do not design packs specifically for taller people however all our packs from the Mountain Series and UL series can be adjusted to fit any body build, size, and physique.
MOLLE (modular lightweight load-carrying equipment) is a universal attachment system compatible with thousands of accessories, including the f-stop Mano bottle holder, Lens Barrels, or the Navin Pouch.
Shallow inserts have a uniform external depth of 5’’/12.7 cm throughout. The Slope insert bottom depth extends on the deeper side to 7’’/17.8cm making it suitable for gripped camera configurations.
The size of the rain cover depends on the backpack that you are using. Small Rain Cover fits the Guru UL. Large Rain Cover fits the Kashmir UL, Loka UL, Lotus, AJNA, Tilopa, Sukha, and SHINN.
The Navin can be used as a chest-carry rig by connecting two pairs of Gatekeeper straps (one pair attached to the top part of the pack, around the shoulder straps and the other pair should be attached to the bottom of the sides of the pack) Alternatively the Navin can be attached on the hip belt using the MOLLE system.
Our Ultra Light and Mountain Series packs can fit a hydration bladder into the main compartment’s drop-in multi-purpose sleeve, with the drinking hose routed through the H20 port.
The front vertical pockets on the Mountain Series and DuraDiamond®️ packs are sized to fit folding avalanche shovels, transceivers, and folding probes.

Yes, f-stop does in fact produce bags for drones. We currently offer the DuraDiamond® Drone Case in both large and small options.

For additional protection we also offer laptop carry cases available through our Accessories shop. (https://shop.fstopgear.com/other-products/accessories/)
The collapsed tripod size will determine whether it can be carried in or outside of the pack. Compact tripods can fit inside the main compartment laid across the insert or stored inside zipper pockets. Standard and larger size tripods are carried on the outside of the pack, attached to either side or center of the pack using Gatekeeper Straps. Enhanced tripod carry is available using our Tripod Bags purchased separately through our Accessories shop. (https://shop.fstopgear.com/other-products/accessories/)

“Nine Iron” is the color name for the Rain Cover. It is a deep steel grey tone.
The Tilopa 50L is certainly suitable for carry-on purposes with air travel. Many of our customers have successfully used the Tilopa as a carry-on while traveling. However, the results will vary depending on the airline, plane size, and how the bag is packed. As always, the loaded camera insert can be removed from the pack and hand carried if the airline requires the pack to be checked in. Other users have successfully carried their larger SHINN 80L backpacks on planes. With this in mind, the f-stop Tilopa 50L is relatively "carry-on" friendly.
