Pactimo Summit Raptor bib shorts



Pretty much the best all round bibs I've tested, this level of comfort and performance usually costs a lot more

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

The Summit line is Pactimo's top end range and after living with these Raptor bibshorts for the past few weeks I can vouch they are very top end and while they're not cheap you would usually expect to pay a lot more for this level of quality and performance.

Colorado based Pactimo have their own factory in China and specialise in custom clothing - they made the original roadcc jerseys - but if you don't want club kit everything is also available in their standard retail range.

The tech spec on the Raptors is impressive, longer than some bike specifications I've seen. Kicking things off is the Raptor material by Swiss company Eschler that has a patterned, almost scaly effect to it which if nothing else certainly looks cool. It uses a nylon outer (66%) which offers great abrasion resistance with 14% Lycra added to create the elasticity giving a mild compression feeling to it.

It's treated with Coldblack, a finishing technology that makes dark fabrics reflect heat rather than absorbing it, keeping the rider cooler in the long run. Unfortunately it hasn't been hot enough to really test it here but the Louis Garneau Course jersey and shorts tested last year used the same stuff and it worked wonders in the sunshine.

The inner lining is polyester (20%) which Pactimo call Flash. Polyester is an inherently hydrophobic material so acts a barrier against moisture being absorbed from the air keeping you dry as you ride.

Loads of technology can't make up for a poor fit though and thankfully with the Raptors it doesn't have to. The cut of the Raptors is pre-shaped which coupled with the supportive characteristics of the material mean they are supremely comfortable and move with you as you stand to climb or crouch on the drops. In fact Pactimo offer a polite warning that bibshorts using their Silhouette Engineering (yep, engineered shorts) will feel odd when you first put them on as they won't feel comfortable until you are on the bike.

The legs stay where they are thanks to 3in wide bands and silicone grippers. Others like Castelli have been using this style of gripper for a while and it's so much more comfortable than elastic.

Cytech provide the Elastic Interface Endurance Anatomic Carbonium chamois, the same that is used in some of Rapha's models plus quite a few others and it's very comfortable even though the padding is quite thick. It's firm enough to stay in position though which is the key, keeping the central channel in place to relieve any perineal pressure.

Pactimo also get high marks for build quality thanks to tight neat stitching of the flatlocked seams and the all round solid feel to the bibshorts. Plenty of miles on various saddles has seen no wear to the Raptor material or the stitching on the inner leg or chamois area. I can't see them wearing out in a hurry.

Overall the Raptors are quite literally beautiful to wear, really comfortable and supportive no matter how long you are in the saddle. The £125 price tag is easily justifiable against some of the more expensive opposition in terms of fit, comfort and all round build quality. Just putting them on makes you feel up for going out for a ride.

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
