Tramplite Custom Made Packs

2017 50L grey pack
Tramplite Gear is currently closed and WILL NOT reopen until trading with the EU becomes viable again.

My first major Make Your Own Gear (MYOG) item was a pack and I've never used a commercial one since. Tramplite packs have evolved beyond recognition since that early example but the core principle of being as light as possible, while still comfort, remains. My 2017 packs have had a major update with a new frame design, increased ventilation and some additional new features.

Original Tramplite pack

Tramplite packs feature an adjustable, internal, tensioned carbon fibre frame. This is comprised of 2 carbon rods held in an arc by a length of adjustable cord. Packs are custom sized to the user but the adjustable arc allows some variation in pack back length and pack shape. Tightening both frames shortens the back length but pushes the pack further away from the body, so ventilation is increased - nice if you have a light pack and are hiking in a hot environment. Lengthening the frame raises the straps and pulls the pack closer to the body - perfect for carrying heavy loads. Each side of the frame can be adjusted individually, if you have one shoulder/hipbone higher then the other then you will appreciate this! Adjustments can be made, on trail, without emptying the pack. In addition there are 4 horizontal carbon rods, on the back panel, that keep the pack shape, help vent the lower back, and transfer the load directly to the hipbelt. The curved back panel doesn't touch the lower back to allow for ventilation, the upper of the pack is in contact with the back but is covered in 3D mesh for comfort. The vertical frames can be easily removed for lightweight trips, or if you prefer a frameless pack, saving 31g. The horizontal rods are not removeable.

Carbon fibre is very tough and incredibly stiff for its weight but is not indestructible. If you over-stress it, chip it, kneel on it, trap it in a car door, sit on it, etc etc, then it can fracture. A fractured frame is easily replaced on your return and can be splinted on trail. Worst case the frame can be removed and the pack used as a conventional frameless pack. If you are heavy on gear then carbon fibre may not be for you and I can offer a slightly heavier but much tougher (and stiffer) fibreglass frame at no additional cost.


Packs are available in 40L or 50L capacity. Volume is calculated for the main compartment only and the side/front pockets will add a few extra litres (around 8L). The 50L pack is sized to easily take most bear canisters and is a very big pack, the 40L pack will take most smaller bear canisters. Pack capacity, of both packs, can be further increased using accessories. Packs have side and rear volume compression cords, 40L packs have a simple single cord side compression system while the 50L pack has a full side compression system from top of pack to side pocket.

Pack dimensions of the 50L pack are 32(w)*19(d)*75(h) cm. The 40L pack is 32(w)*16(d)*75(h) cm.

When deciding which pack to get it might be wise to measure one you already have as many producers would rate my 50L pack nearer 60L and the 40L nearer 50L.

*Actual height of the pack varies slightly with back length

Gear access

Tramplite packs have the option to access gear from the top or bottom. The bottom opening is closed using a combination of clip/cords and is further held tightly shut by the shoulder straps when carried. The top has a standard rollover opening (like a drybag) and is further secured using a “V Top” elasticated cord.

Packs are bladder compatible and have a hydration port that allows the drinking tube to pass over the left or right shoulder. It should work with most bladders as long as the hose and mouthpiece fit through the hole but it was designed around the Hydropak Reversible Reservoir (currently the best bladder available). The bladder is laid horizontally inside the pack.

Straps - The body contoured shoulder straps are extra wide and contain 10mm thick 50Nm foam (upper chamber) and 6mm thick 30Nm (lower chamber) and is user replaceable. This is a feature you will appreciate if you do really long hikes and, as far as I’m aware, exclusive to Tramplite packs (Gossamer Gear used to have open straps years ago). This medical grade Evazote foam is held in 2 clipped chambers and then covered in 3mm 3D mesh for ventilation and additional padding. You could vary the amount of padding in each chamber, or remove it completely (there really isn't much need for padding in the lower chamber), and replace it completely should it get thin on a long hike. Shoulder straps adjust using linelocs and nylon covered dyneema cord threaded so they never slip, even after 3000mi continuous hiking on the CDT I never had to re-adjust these straps. Should the cord ever wear out it's easily replaced without tools.

Hipbelt - is body contoured and has 3 clipped chambers of replaceable 10mm thick 50Nm foam and 3mm 3D mesh. The centre chamber is lined with plastic to prevent deformation under load. The hipbelt uses “V style” webbing so top and bottom circumference can be adjusted individually, giving a more secure and comfortable fit. Hipbelts are available in 3 sizes and are sewn directly to the pack. A carbon rods then transfers the pack load directly to the plastic lined centre chamber of the hipbelt. Hipbelt straps are user replaceable without tools.

Back - the upper back panel is covered in 3mm 3D mesh for comfort and padding.

Packs have 2 large adjustable side pockets, slanted forward for access on the trail, and a mesh rear pocket. I don't use mesh for side pockets as they have a habit of snagging on foliage. Side pockets are ice axe compatible, slot your ice axe through the side compression cord and the shaft fits through a slit in the side pocket base. Having your axe here allows access without removing your pack. There are also 2 conventional ice axe loops on the rear if you prefer your axe there. The rear mesh pocket uses a tougher mesh than on many lightweight packs but it's the lightest that I've failed to tear on a long multi-month hike.

Packs are individually handmade in the UK, by Tramplite, using the finest materials from around the world. My background is in aeronautical engineering where doing every job correctly, and to a standard above the norm, is all I knew for 23 yrs. That's something I try and bring to my packs.

Packs are currently made from 210 denier Gridstop Fabric as it’s one of the best pack fabrics available and most suited to these packs. All seams are at least double sewn, many are triple sewn, and some parts are bonded. 

Packs are available in a single colour of jet black or grey, or a twin colour of jet black (straps, backpanel, hipbelt) and your choice of autumn orange, slate blue, moss green for everything else.

Standard features

Packs come with a built-in safety whistle on the top opening,  3 position adjustable chest strap (removable), daisy chain webbing on straps and hipbelt for pockets and other accessories.


The hipbelt has 2 clips for directly attaching Tramplite accessories. I use 2 accessories on my hikes, a 4L waterbag (for desert crossings), and if I need to increase pack capacity then my bear food hanging bag attaches directly, and can carry another 5-7 days food. Carrying heavy items, like 4ltr water, up front has a number of advantages in balance and space saving and whatever you carry up front, when attached directly to the hipbelt, will not be felt on your shoulders. Other items that could be carried here are a packraft or heavy camera system.

Pockets - new for 2018 I've redesigned the hipbelt to be useable with 2 hipbelt pockets as well as Tramplite accessories. Pockets will be supplied as a pair and are available in single or twin colour to match your pack.

Backrest - Packs can convert into a backrest for long comfy breaks on the trail. 2 mini pockets clip into the side compression system and hiking poles handles are inserted. The tips of the hiking poles slip into a cord brace which is attached to the bottom of the pack. This gives you a solid backrest that will stay put on any surface (on a particularly smooth surface, such as flat sun baked mud, I recommend fastening the hipbelt to stop the pack bottom sliding).

The backrest should only be used with a loaded pack, use around camp with an empty pack could over-stress the frame causing catastrophic failure.

Pack liner - I'm working on a new lightweight nylon pack liner to replace the cuben version I used to offer. Tramplite pack liners are full size and have a cord opening at both ends. The new nylon version will be more waterproof but a little heavier. 

Travel bag - Heavy duty 1.4oz cuben travel bag that converts into a pack liner when not traveling. Useful when flying with your pack, simply slip the loaded pack into the travel bag (pockets need to be empty) and when you get to the other end the bag becomes your pack liner. Baggage handlers will struggle to rip the heavy duty 1.4oz cuben but they may put an odd hole in it which will be easily fixed with the supplied repair tape. This is a copy of the Zpacks travel bag but sized to fit my packs and with a rollover opening at both ends to allow easy access to pack contents from top and bottom.
