Over the years daypacks have become increasingly complex. The Built To Send U1 daypack - the first from the brand - isn’t like this.

Over the years daypacks have become increasingly complex. Many have adjustable backs, internal frames, and padded hipbelts just like those found on large backpacking packs. Multiple pockets and external straps are common too. The Built To Send U1 daypack – the first from the brand – isn’t like this.

There are no external pockets, no frame, no padded hipbelt, no compression straps, no lid. Built To Send describes it as “ultra-minimal”. It’s not quite that as it does have a padded back and bungee cord and attachment loops on the front, but the design is simple compared to most daypacks.

Built to Send C1 Chalk Bag 

There isn’t very much to say about chalk bags. You put chalk in, tie them round your waist and go climbing. a chalk bag is a simple item of equipment. However I found myself really liking this one and have felt compelled to write a few words.


Built to Send are a small, UK based company currently making very light and durable packs, stuff sacks and chalk bags. In their own words they ‘make obsessively engineered rucksacks for alpinists, climbers and ultralight backpackers. Our equipment, which is custom engineered and hand-built in the UK, is the ultimate in bombproof simplicity. Our team combines the skills of experienced design engineers, climbers and exceptional craftsmen.’

Carryology: 10 UK Brands You Should Know

Britain certainly has its share of illustrious brands in the luxury carry scene. Think the likes of Globe-Trotter or Burberry.

So we’re set on changing that, flipping the switch on that spotlight and shining some carry love on 10 UK brands you should know…

For light weight missions where not much kit is required then the U1 is a definite winner. 

When Paul at BTS mentioned he’d be sending me a U1 pack as soon as it was in production, I’ll have to be honest and say that I wasn’t super excited. However, with the superb weather over the last month, the U1 has come into it’s own. It has proved itself a fantastic choice for hill days when smaller amounts of kit are required.

On arrival, I was impressed by the construction and design of the U1 but did wonder if it was a tad on the small side. ATCer, Louise Kennedy had ordered her U1 in black and from it’s arrival used it extensively in the Cuillin and raved about it’s Tardis like capacities.

Built To Send X2 Rucksack Review

As an instructor, and obsessive mountaineer/climber, a bug bear of mine is buying kit/equipment that does not last.  When it comes to rucksacks, I have been through 5 of them in the last 4-5 years.  Mainly because these are designed with less than sufficient materials, to withstand the abuse these are designed for.  I am not professing to have experience with all brands of rucksacks out there.

So, I recently came across a new brand of rucksacks on the market from Built To Send.  And I was very intrigued by their engineering-led design.  They state that their rucksacks are “the strongest on planet earth” and “bombproof”.  So, of course I had to put this to the test.  Here we have reviewed the Built To Send X2 rucksack.

Built To Send X-Series Pack Review

For roughly the last two months I have been been using and testing the Built To Send (BTS) X0 Alpine Pack. I have used it extensively during what has been a very busy summer of guiding on everything from Mont Blanc, the Matterhorn and the Eiger, to an ascent of the Badile North Ridge, a trip to the Dolomites and everything in-between. BTS are a relatively new brand on the market place and looking on their website they promise a lot. So when I heard about them, their products and their ethos I was keen to find out more. So what was the outcome? Read on to find out..

Expensive Niche Product Or Simply the best…A Review Of Built To Send’s X2 Pack

This review comes after only having the Built To Send X2 pack for 24 days however it’s been put through it’s paces fairly intensively in that short time. Guiding work here in the Cuillin on the Isle of Skye has never been busier and out of 24 days of ownership the X2 has been used for 17 days of guiding and 3 days of photography.


I’m not normally one for statistics but recent clients have been studiously monitoring their progress and during the guiding have covered 134 miles and 18,323 metres of ascent. We’ve enjoyed (or not) a wide range of weather from glorious sunshine and amazing temperature inversions to days of high winds and torrential rain. The Cuillin rock, especially the gabbro has a well deserved reputation for abrasiveness and trashes gear and finger tips alike.

Carryology: 5 Reasons Why BUILT TO SEND Should Be on Your Radar

Lasers, rocket engineering, 3D printers, F-16 fighter jets…..we are talking about bags here, right? You may not know British pack makers BUILT TO SEND yet, but you should. Everything Built To Send does is focused on achieving engineering perfection and they may well get there; with three PhD level engineers on their team and extensive experience in aerospace, automotive and rocket engineering – to say they are well suited to the task of building a bomber bag is starting to sound like an understatement.

Built To Send X0 pack initial impressions

Built To Send packs are made to be abused and keep kicking. Built To Send doesn’t cut any corners in their material choices or construction. Most big name climbing pack brands are made of a flimsy 100d or 200d coated ripstop nylon. These materials are fine for on-trail daypacks, but they have absolutely no durability when it comes to alpine climbing or heavy cragging. BTS uses VX42 x-pac on their entire bag with big seam allowances. They use a heavy duty sail and vinyl thread (v92) to double and triple stitch the structural seams of the pack. When I flipped the pack inside out, I was impressed at how big the seam allowances were and how many bar tacks they used. The pack seams are bound with a much thicker webbing than the typical grosgrain most packs are bound with. They paid an incredible amount of attention to detail, and it shows.
