Here is a pair of bib that is extremely well designed and comfortable. It offers good support and pull moisture away from the body effectively. Most importantly, it looks nice!
Thanks for the 5 stars! We appreciate your continuous support and we are delighted to keep hearing rave reviews on the bibshorts. Keep riding and keep those photos coming!
Really comfortable bibs. Thin and comfortable. I just did a 70km ride with it, no discomfort in my groin area.
Thanks for the great review! We're really glad you're enjoying our bibs!
For reference I'm a 169cm, 62kg rider wearing XS
Material : feels great, the seamless construction is nice and the fabric doesn't feel scratchy at any parts
Chamois : at first I was apprehensive at the thin layer of Chamois but to my surprise thinner is better for me. The material doesn't bunch up and move around. I used to use redwhites bibs and the Chamois would bunch up alot more. Whatever the pack is using here is great (for me)
Price: considered affordable already in the face of $200+ $300+ bibs from the poser brands
The first bib shorts that I don't have issues with for my 25 years of cycling! Very comfortable and top quality.
These pair of bib shorts are brilliant! Second order from the website after a few thousand kms in the first pair. They hold up really well. Well worth the money!
Very comfy and firm. Felt good power transfer through to saddle and the fit was great.
Shorts are comfortable for longer rides, and good quality materials. Shoulder straps are prone to bunching up or getting twisted.
Very happy with the performance and looks of the bibs. Extremely suitable for Singapore weather.
This is my 4th Purchase, The New Design of the Bib os very Comfortable yet very high End looking. What makes this Bib really nice is the Logo is Sutle and very neath.
Excellent bib at a very affordable price point. Great for longer rides.
Tho my package was delayed by a week, I would like to thank Jiazheng for his excellent customer service follow up,ensuring his customers are completely satisfied with the product. I ordered a M but found it tight at the groin area.He was kind enough to arrange a meetup for me to try a L.The fit was to the tee, fabric was soft but yet snug and the padding was dense tho it looked thin.Kudo to him and I enjoyed my ride this morning. He even brought jersey for me try the fit and fabric.Will definitely recommend it, for the product and his service delivery.

At first I thought the padding not good as it is just a thin layer. But it surprised me and hold up to the end of my ride.
These bib shorts are very comfy (material is very soft to touch) and the chamois is dense which I prefer. Good value in my opinion. Worth a try.
I have worn bibs from almost all the mainstream cycling apparel brands and this is surely one of the better quality and value ones. Comfortable shammy, hugs thighs nicely and looks good too. 100% recommended.
Good also to support local independent businesspersons!
Bibs are very comfy!
Got the Alpha bibs. First ride impression is super positive.
Very comfortable, no chafing & look great. Will but more!
Thanks for your positive feedback and kind words! Happy to see you enjoying your rides with the Alpha bibs! Look forward to your support in future and happy riding! :)
One of the most comfortable bib shorts I have had the pleasure of wearing
Thank you for your 5 stars and kind words! It just gives us so much pleasure to hear our riders enjoying the comfort of the bibshorts! Happy riding!
Second set from The Pack! Super value for money and super comfy. I can’t seem to find anything out there that is able to match such comfort without burning a hole in the pocket.
Hi Landy! Thank you for your positive review and kind words! We are very happy to know that we have helped to bring superb comfort for your rides and pocket! Happy cycling!
Very comfortable set. Material is gentle to skin and stretchable.
Thank you Andy! We hope that the Alpha bibs are making your rides more comfortable than before! Appreciate your review! :)
This is my third set from The Pack. The first 2 are the classic ones which I thought are already top notch. First ride 114km with the Alpha set last week. It was wet and cold but bibs and jersey held up really well. Never felt inhibited despite it been very tight fitting. While the chamois felt thinner it offers the same level of comfort as the classic hence you almost felt it’s not even there.
Thank you WM for your kind words and support of our products! We are indeed very happy to know that our Alpha bibs and jersey have played an important role in providing much-needed comfort on your long ride!
Been using the The Pack for months now and Now upgraded to their New Bib Version and is Improved. Comfortable, Solid Quality and affordable
Thank you for the kind words! We appreciate the review of our Alpha Bibs and we will continue to work hard to bring you more comfortable cycling apparel in the future!
My favourite pair of bib shorts (and I have tried bib shorts from Castelli, Ale, DHB, Van Rysel, Decathlon, Pedla and Endura)! Don’t be deceive by its seemingly not so thick chamois because it does an excellent work in keeping your butt comfortable during long and hard efforts be it on the flats and up the climbs. The bibs feels very gentle on the body and stretches well. The shorts material feels luxurious and wraps around your thighs very comfortably. The Olive colour is unique (not the usual black and blue bib shorts) and matches well with white or black coloured jersey too! M size is perfect for a 86cm waist.
Hi Ervin! Thanks for taking time to write this, and sorry for replying late! We appreciate your kind feedback on our bibs, and are very happy that you are enjoying everything good about it - the comfort, fabric, colour and the fit. Thank you!
